Conventions We have translated amounts from Renminbi into U.S. dollars solely for the convenience of the reader at the noon buying rate in New York for cable transfers payable in foreign currencies as certified for customs purposes by the Federal Reserve Bank of New York on December 30, 2005 of US$1.00=Rmb 8.0702. We have also translated amounts in Hong Kong dollars solely for the convenience of the reader at the rate of HK$7.80 to US$1.00, the linked exchange rate between such currencies under policies of the Hong Kong government in effect on December 31, 2005. We make no representation that the Renminbi amounts or Hong Kong dollar amounts could have been, or could be, converted into U.S. dollars at those rates on December 31, 2005, or at all. For further information on exchange rates, see Item 3 "Key Information--Selected Financial Data." Totals presented in this annual report may not total correctly due to rounding of numbers. Our "average net realized price" for oil and gas in each period is derived from a numerator divided by a denominator, where: o the numerator is equal to the sum of (i) revenues from our oil and gas sales offshore China for the applicable period; (ii) the 30% ownership share of revenues from gas sales for the applicable period from our associated company, Shanghai Petroleum and Natural Gas Company Limited; and (iii) the revenues from oil and gas sales for the applicable period from our overseas interests; while: o the denominator is equal to the sum of (i) the volume of oil and gas sales offshore China for the applicable period; (ii) 30% of the volume of gas sales for the applicable period from our associated company, Shanghai Petroleum and Natural Gas Company Limited; and (iii) the volume of oil and gas sales for the applicable period from our overseas interests. 1 Our "net proved reserves" consist of our percentage interest in reserves, including our 100% interest in the independent oil and gas properties and our participating interest in the properties covered under the production sharing contracts in the PRC, less: (a) an adjustment for our share of royalties payable by us to the PRC government and our participating interest in share oil payable to the PRC government under the production sharing contracts, and (b) an adjustment for production allocable to foreign partners under the PRC production sharing contracts as reimbursement for exploration expenses attributable to our participating interest; and plus (i) our 5.3% participating interest in North West Shelf Project in Australia, and (ii) our participating interest in the properties covered under the production sharing contracts in Indonesia less an adjustment for share oil attributable to the Indonesian government and the domestic market obligation. In this annual report, we use "share oil" to refer to the portion of production that must be allocated to the relevant government entity or company under our production sharing contracts. Net proved reserves do not include any deduction for production taxes payable by us, which are included in our operating expenses. Net production is calculated in the same way as net proved reserves. Unless otherwise noted, all information in this annual report relating to oil and natural gas reserves is based upon estimates prepared by us. In calculating barrels-of-oil equivalent, or BOE, amounts, we have assumed that 6,000 cubic feet of natural gas equals one BOE, with the exception of natural gas from certain fields which is converted using the actual heating value of the natural gas. Glossary of Technical Terms Unless otherwise indicated in the context, references to: o "API gravity" means the American Petroleum Institute's scale for specific gravity for liquid hydrocarbons, measured in degrees. The lower the API gravity, the heavier the liquid and, generally, the lower its commercial value. For example, asphalt has an API gravity of eight degrees, West Texas Intermediate, a benchmark crude oil, has an API of 40 degrees, and gasoline has an API gravity of 50 degrees. o "appraisal well" means an exploration well drilled after a successful wildcat well to gain more information on a newly discovered oil or gas reserve. o "condensate" means light hydrocarbon liquids separated from natural gas in the field through condensation when natural gas is exposed to surface temperature and pressure. This group generally includes slightly heavier hydrocarbons than natural gas liquids, such as pentane. It is combined with crude oil production and reserve figures. o "crude oil" means crude oil and liquids, including condensate, natural gas liquids and liquefied petroleum gas. o "development cost" means, for a given period, costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering and storing the oil and gas. o "dry hole" means an exploration well that is not commercial (i.e., economically feasible to develop). Dry hole costs include the full costs for such drilling and are charged as an expense. o "exploration well" means a wildcat or appraisal well. o "lifting cost" means, for a given period, costs incurred to operate and maintain wells and related equipment and facilities, including applicable operating costs of support equipment and facilities and other costs of operating and maintaining those wells and related equipment and facilities, plus production taxes. Also known as production cost. The U.S. dollar amount of the lifting cost in this annual report may be different from what we disclosed in Hong Kong annual report due to the usage of different conversion rates. 2 o "natural gas liquids" means light hydrocarbons that can be extracted in liquid form from natural gas through special separation plants. This group includes typically lighter liquid hydrocarbons than condensate, such as butane, propane and ethane. It is combined with crude oil production but not with crude oil reserve figures. o "net wells" means a party's working interest in wells. o "proved developed reserves" means proved reserves of oil and natural gas that can be expected to be recovered through existing wells with existing equipment and operating methods. o "proved reserves" means estimated quantities of crude oil and natural gas that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made. o "proved undeveloped reserves" means proved reserves that are expected to be recovered from new wells in undrilled areas, or from existing wells where significant expenditure is required for completion. For further definitions relating to reserves: o "reserve replacement ratio" means, for a given year, total additions to proved reserves divided by production during the year. o "reserve-to-production ratio" means the ratio of proved reserves to annual production of crude oil or, with respect to natural gas, to wellhead production excluding flared gas. o "seismic data" means data recorded in either two-dimensional (2D) or three-dimensional (3D) form from sound wave reflections off of subsurface geology. This is used to understand and map geological structures for exploratory purposes to predict the location of undiscovered reserves. o "success" means a discovery of oil or gas by an exploration well. Such an exploration well is a successful well and is also known as a discovery. A successful well is commercial, which means there are enough hydrocarbon deposits discovered for economical recovery. o "success rate" means the total number of successful exploration wells divided by the total number of exploration wells drilled in a given period. Success rate can be applied to wildcat wells or appraisal wells in general. o "wildcat well" means an exploration well drilled in an area or rock formation that has no known reserves or previous discoveries. References to: o bbls means barrels, which is equivalent to approximately 0.134 tons of oil (33 degrees API); o mmbbls means million barrels; o BOE means barrels-of-oil equivalent; o BOE per day means barrels-of-oil equivalent per day; o million BOE means million barrels-of-oil equivalent; o mcf means thousand cubic feet; 3 o mmcf means million cubic feet; o bcf means billion cubic feet, which is equivalent to approximately 283.2 million cubic meters; o BTU means British Thermal Unit, a universal measurement of energy; and o km means kilometers, which is equivalent to approximately 0.62 miles. 4 FORWARD-LOOKING STATEMENTS This annual report includes "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this annual report that address activities, events or developments which we expect or anticipate will or may occur in the future are forward-looking statements. The words "believe," "intend," "expect," "anticipate," "project," "estimate," "predict" and similar expressions are also intended to identify such forward-looking statements. These forward-looking statements address, among others, such issues as: o the amount and nature of future exploration, development and other capital expenditures, o wells to be drilled or reworked, o oil and gas prices and demand, o future earnings and cash flow, o development projects, o exploration prospects, o estimates of proved oil and gas reserves, o potential reserves, o development and drilling potential, o drilling prospects, o expansion and other development trends of the oil and gas industry, o business strategy, o production of oil and gas, o development of undeveloped reserves, o expansion and growth of our business and operations, and o our estimated financial information. These statements are based on assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions and expected future developments, as well as other factors we believe are appropriate under the circumstances. However, whether actual results and developments will meet our expectations and predictions depend on a number of risks and uncertainties which could cause our actual results, performance and financial condition to differ materially from our expectation. For a description of such risks and uncertainties, see "Item 3-Key Information-Risk Factors." Consequently, all of the forward-looking statements made in this annual report are qualified by these cautionary statements. We cannot assure that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected effect on us or our business or operations. 5 PART I ITEM 1.

OFFER STATISTICS AND EXPECTED TIMETABLE Not applicable. ITEM 3. KEY INFORMATION A. SELECTED FINANCIAL DATA You should read our selected historical consolidated financial data set forth below in conjunction with our consolidated financial statements and their notes under "Item 18--Financial Statements" and "Item 5--Operating and Financial Review and Prospects" in this annual report. On June 6, 2002, Ernst & Young replaced Arthur Andersen & Co as our independent public accountants. For a discussion on such change of accountants, see "Item 3--Key Information--Risk Factors--Risks relating to our business--You may not be able to assert claims against Arthur Andersen, our independent public accountants for periods prior to 2002, nor may you be able to assert claims against our current independent public accountants for financial statements previously audited by Arthur Andersen" and "Item 5--Operating and Financial Review and Prospects--Change of Accountants." The Hong Kong Institute of Certified Public Accountants issued a number of new standards and interpretations, effective January 1, 2005, which are applicable to our financial statements for the fiscal year ended on December 31, 2005. Certain prior year amounts have been restated upon adoption of such new policies, details of which are included in note 2.4 to our consolidated financial statements under "Item 18--Financial Statements" in this annual report. We have prepared and presented our consolidated financial statements in accordance with Hong Kong generally accepted accounting principles ("Hong Kong GAAP"). For an explanation of the reconciliation of our net income and shareholders' equity to U.S. generally accepted accounting principles ("US GAAP"), see note 37 to our consolidated financial statements under "Item 18--Financial Statements" in this annual report. 6 Year ended December 31, -------------------------------------------------------------------------------- 2001(g) 2002 2003 2004 2005 2005 -------- -------- -------- -------- -------- ------- Rmb Rmb Rmb Rmb Rmb US$ -------- -------- -------- -------- -------- ------- (in millions, except per share and per ADS data) Income Statement Data: Hong Kong GAAP (Restated) (Restated) (Restated) Operating revenues: Oil and gas sales............................ 17,561 23,779 28,117 36,886 53,418 6,619 Marketing revenues........................... 2,537 2,377 12,399 18,191 15,901 1,970 Other income................................. 722 217 434 145 137 17 -------- -------- -------- -------- -------- ------- Total operating revenues..................... 20,820 26,374 40,950 55,222 69,456 8,606 -------- -------- -------- -------- -------- ------- Expenses: Operating expenses...........................

The stock split was effected by dividing each of our issued and unissued shares of HK$0.10 each into five shares of HK$0.02 each, and to increase the board lot size for trading on the Hong Kong Stock Exchange from 500 shares of HK$0.10 each to 1,000 subdivided shares of HK$0.02 each. The ratio of our ADSs listed on the New York Stock Exchange also changed such that each ADS now represents 100 subdivided shares of HK$0.02 each, as opposed to 20 shares of HK$0.10 each prior to the stock split. As such, per share amounts of our shares have been adjusted retroactively for the stock split. (b) Net income per share (basic) and net income per ADS (basic) for 2001 have been computed, without considering the dilutive effect of the shares underlying our share option scheme, by dividing net income by the weighted average number of shares and the weighted average number of ADSs of 39,706,916,525 and 397,069,165 respectively (based on a ratio of 100 shares to one ADS) for the period. Net income per share (basic) and net income per ADS (basic) for 2002 have been computed, without considering the dilutive effect of the shares underlying our share option scheme, by dividing net income by the weighted average number of shares and the weighted average number of ADSs of 41,070,828,275 and 410,708,283 respectively (based on a ratio of 100 shares to one ADS) for the period. Net income per share (basic) and net income per ADS (basic) for 2003 have been computed, without considering the dilutive effect of the shares underlying our share option scheme, by dividing net income by the weighted average number of shares and the weighted average number of ADSs of 41,070,828,275 and 410,708,283 respectively (based on a ratio of 100 shares to one ADS) for the period. Net income per share (basic) and net income per ADS (basic) for 2004 have been computed, without considering the dilutive effect of the shares underlying our share option scheme and convertible bonds, by dividing net income by the weighted average number of shares and the weighted average number of ADSs of 41,060,240,659 and 410,602,407 respectively (based on a ratio of 100 shares to one ADS) for the period. Net income per share (basic) and net income per ADS (basic) for 2005 have been computed, without considering the dilutive effect of the shares underlying our share option scheme and convertible bonds, by dividing net income by the weighted average number of shares and the weighted average number of ADSs of 41,054,499,982 and 410,545,000 respectively (based on a ratio of 100 shares to one ADS) for the period. (c) Net income per share (diluted) and net income per ADS (diluted) for 2001 have been computed, after considering the dilutive effect of the shares underlying our share option scheme, using 39,711,444,015 and 397,114,440 respectively. Net income per share (diluted) and net income per ADS (diluted) for 2002 have been computed, after considering the dilutive effect of the shares underlying our share option scheme, using 41,096,426,920 and 410,964,269 respectively. Net income per share (diluted) and net income per ADS (diluted) for 2003 have been computed, after considering the dilutive effect of the shares underlying our share option scheme, by using 41,110,339,095 and 411,103,391 respectively. Net income per share (diluted) and net income per ADS (diluted) for 2004 have been computed, after considering the dilutive effect of the shares underlying our share option scheme and convertible bonds, by using 41,179,513,436 and 411,795,134 respectively. Net income per share (diluted) and net income per ADS (diluted) for 2005 have been computed, after considering the dilutive effect of the shares underlying our share option scheme and convertible bonds, by using 42,386,055,766 and 423,860,558 respectively. (d) The proposed final dividend and special final dividend for 2003 were cancelled and replaced by the special interim dividend of HK0.06 per share declared and paid in 2004. (e) In periods prior to 2005, no recognition and measurement of share-based transactions in which employees (including directors) were granted share options in our company were required until such options were exercised by the employees, at which time the share capital and share premium were credited with the proceeds received. In 2005, we have adopted the provisions of Hong Kong Financial Reporting Standard ("HKFRS") retrospectively to all stock options granted from the date of our incorporation. Under HKFRS 2, when employees (including directors) render services as consideration for equity transactions ("equity-settled transaction"), the cost of equity-settled transaction is measured by reference to the fair value on the date on which the instrument is granted. 8 (f) Certain prior year amounts have been restated upon adoption of new Hong Kong accounting policies, details of which are included in note 2.2 to our financial statements (under HK GAAP). In prior periods, we classified the on-shore processing plants as land and buildings and depreciated over 30-50 years on a straight-line basis. Upon the adoption of HKAS 16, we have retrospectively reclassified our property, plant and equipment into two categories: oil and gas properties, and vehicles and office equipment. We have reclassified the onshore terminals previously classified as land and buildings to oil and gas properties as they will be used in similar operations and are expected to have similar economic useful lives. We have also changed our accounting policy retrospectively for 2002, 2003 and 2004 to state the onshore terminals at cost instead of valuation and to amortize those terminals by the unit-of-production method on a property-by-property basis. (g) The 2001 selected consolidated income statement data and consolidated balance sheet data were audited by Arthur Anderson & Co., which voluntarily relinquished its license to practice public accounting in 2002. Our current auditors, Ernst & Young, have not reaudited the financial statements of 2001. As such, no restatement was made for 2001 as the impacts on the consolidated financial statements are considered not material.

We publish our financial statements in Renminbi. Unless otherwise indicated, all translations from Renminbi to U.S. dollars have been made at a rate of Rmb 8.0702 to US$1.00, the noon buying rate as certified for customs purposes by the Federal Reserve Bank of New York on December 30, 2005. We do not represent that Renminbi or U.S. dollar amounts could be converted into U.S. dollars or Renminbi, as the case may be, at any particular rate, the rate below or at all.

The Hong Kong dollar is freely convertible into the U.S. dollar. Since 1983, the Hong Kong dollar has been linked to the U.S. dollar. The Hong Kong government has also stated that it has no intention of imposing exchange controls in Hong Kong and that the Hong Kong dollar will remain freely convertible into other currencies, including the U.S. dollar. However, we cannot assure that the Hong Kong government will maintain the link at HK$7.80 to US$1.00 or at all.

CAPITALIZATION AND INDEBTEDNESS Not applicable. C. REASONS FOR THE OFFER AND USE OF PROCEEDS Not applicable. D. RISK FACTORS Risks relating to our business Our business, revenues and profits fluctuate with changes in oil and gas prices Even relatively modest declines in crude oil prices may adversely affect our business, revenues and profits. Our profitability is determined in large part by the difference between the prices received for the crude oil we produce and the costs of exploring for, developing, producing and selling these products. 10 Prices for crude oil fluctuate widely in response to relatively minor changes in the supply and demand for oil, market uncertainty and various other factors that are beyond our control, including: o political developments in petroleum producing regions; o the ability of the Organization of Petroleum Exporting Countries and other petroleum producing nations to set and maintain production levels and prices; o the price and availability of other energy sources, such as coal; o domestic and foreign government regulations; o weather conditions; and o overall economic conditions. Our revenues and net income have increased significantly in the past five years, mainly due to increasing oil prices. However, we can not assure that oil price will remain high in the future. In 2005, oil prices for West Texas Intermediate, the international benchmark for crude oil, rose 44.9% from US$42.13 per barrel on January 3, 2005 to US$61.04 per barrel on December 30, 2005. The conflict and turmoil in the Middle East in the past three years raised concerns about the security and availability of ample supplies to meet growing global demand. West Texas Intermediate reached a high in 2005 of US$69.82 per barrel on August 30, 2005 and was US$72.50 per barrel on June 6, 2006. For a description of oil prices in recent years, see "Item 4--Information on the Company--Business Overview--Sales and Marketing--Sales of Offshore Crude Oil--Pricing" in this annual report. Any future declines in oil and gas prices would adversely affect our revenues and net income. The prices for the natural gas we sell are determined by negotiations between us and the prospective buyers. Our typical contracts with gas buyers include provisions for periodic resets and adjustment formulas that depend on a basket of crude oil prices and inflation as well as various other factors. These resets and adjustment formulas can result in natural gas price fluctuations which may adversely affect our business, results of operations and financial condition. Lower oil and gas prices may result in the write-off of higher cost reserves and other assets and may lower our earnings or cause losses. Lower oil and natural gas prices may also reduce the amount of oil and natural gas we can produce economically and render existing contracts that we have entered into uneconomical. For further details regarding the effects of oil and gas price fluctuations on our financial condition and results of operations, see "Item 5--Operating and Financial Review and Prospects." The oil and gas reserve estimates in this annual report may require substantial revision as a result of future drilling, testing and production The reliability of reserves estimates depends on a number of factors, including: o the quality and quantity of technical and economic data; o the prevailing oil and gas prices for our production; o the production performance of reservoirs; o extensive engineering judgments; and o royalty and share oil policies in the PRC and foreign countries and regions where we have operations or assets. Many of the factors, assumptions and variables involved in estimating reserves are beyond our control and may prove to be incorrect over time. Consequently, the results of drilling, testing and 11 production may require substantial upward or downward revisions in our initial reserves data. For more information on our oil and gas reserves data, see "Item 4--Information on the Company--Business Overview--Oil and Natural Gas Reserves." Any failure to develop our proved undeveloped reserves and gain access to additional reserves could impair our ability to achieve certain growth objectives Our ability to achieve certain growth objectives depends upon our success in finding and acquiring or gaining access to additional reserves. Future drilling, exploration and acquisition activities may not be successful. If our exploration and development activities or acquisition of properties containing proved reserves are unsuccessful, our total proved reserves will decline. Approximately 50.9% of our proved reserves were undeveloped as of December 31, 2005. Our future success will depend on our ability to develop these reserves in a timely and cost-effective manner. There are various risks in developing reserves, including construction, operational, geophysical, geological and regulatory risks. Our future prospects largely depend on our capital expenditure plans, which are subject to various risks The oil and gas exploration and production business is capital intensive. We currently plan to spend US$2,233.2 million to develop our oil and gas properties and US$457.8 million for exploration in 2006. In addition to these amounts, we may make additional capital expenditures and investments to implement our business strategy. The ability to maintain and increase our revenues, net income and cash flows depends upon continued capital spending. We adjust our capital expenditure and investment budget each year. Our capital expenditure plans are subject to a number of contingencies, some of which are beyond our control. These variables include: o our ability to generate sufficient cash flows from operations to finance our capital expenditures, investments and other requirements; o the availability and terms of external financing; o changes in crude oil and natural gas prices, which may affect cash flows from operations and capital expenditure and investment plans; o the mix of exploration and development activities conducted on an independent basis and under production sharing contracts; o new investment opportunities that may be presented to us, including international investment opportunities and liquefied and other natural gas projects; o approvals required from foreign governments for certain capital expenditures and investments outside the PRC; o our ability to obtain sufficient foreign currency to finance our capital expenditures; and o economic, political and other conditions in the PRC and in foreign countries and regions where we have operations. Therefore, our actual capital expenditures and investments in the future may differ significantly from our current planned amounts. There can be no assurance that we will be able to execute our capital expenditure program on schedule or as planned. 12 Any failure to implement our natural gas business strategy may adversely affect our business and financial position As part of our business strategy and to meet increasing market demand in China, we continue to expand our natural gas business. This strategy involves a number of risks and uncertainties including the following: o we have limited experience in investing in liquefied natural gas facilities, gas transmission and distribution systems, and overseas upstream natural gas properties; o any additional capital expenditures that are necessary to implement our natural gas strategy could divert resources from our core oil and gas exploration and production business and require us to seek additional financing; o our new natural gas operations may face additional competition from a number of international and PRC companies. In particular, PetroChina Company Limited, or PetroChina, has constructed natural gas pipelines to link its natural gas fields located in the western part of China to the eastern coastal regions; o our new natural gas activities may subject us to additional government regulation in China and foreign countries and regions; o our overseas natural gas businesses are subject to economic and political risks in the relevant countries and regions. See "--We are exposed to operating risks in some foreign countries and regions as a result of our acquisition of oil and gas interests located in these regions;" o we do not have the same preferential rights or access to natural gas businesses or overseas natural gas investments that we enjoy with respect to our upstream natural gas business offshore China; and o we are evaluating the options to invest in CNOOC's liquefied natural gas projects in China. However, we have not decided whether to exercise these options. The options are subject to various conditions, including the receipt of certain governmental approvals. Due to the above factors or other reasons, we may fail to implement our natural gas strategy successfully. The infrastructure and demand for natural gas in the PRC may proceed at a slower pace than our planned increase in production Our proposed expansion of natural gas production in China is currently constrained by a lack of natural gas transmission and supply infrastructure and an underdeveloped natural gas market. Construction of transmission and supply pipelines and other infrastructure depends on many factors, many of which are beyond our control, such as funding, costs of land acquisition, national and local government approvals, and timely completion of construction. Development of the natural gas market depends on the establishment of long-term natural gas supply contracts with natural gas utilities or large end-users, such as power and chemical plants. The demand of these buyers for natural gas could be affected by a number of regulatory and market factors, such as regulation of coal prices, government power and utility policies, chemical commodity cycles, electricity pricing and demand, and environmental policies. CNOOC largely controls us and we regularly enter into related party transactions with CNOOC and its affiliates CNOOC indirectly owned 66.41% of our shares as of June 6, 2006. As a result, CNOOC is able to control the composition of our board of directors, determine the timing and amount of our dividend payments and otherwise control us. Although CNOOC is required to comply with provisions in the Hong 13 Kong Stock Exchange Listing Rules relating to protection for minority shareholders, there can be no assurance that CNOOC will act in a manner that benefits all of our shareholders. If CNOOC takes actions that favor its interests over ours, our results of operations and financial position may be adversely affected. We regularly enter into transactions with CNOOC and its affiliates, including China Oilfield Services Limited and Offshore Oil Engineering Company Limited. For the year ended December 31, 2005, sales to CNOOC and its affiliates accounted for 38.3% of our total revenues. For further details, see "Item 7--Major Shareholders and Related Party Transactions." Our transactions with CNOOC and its affiliates constitute connected transactions under the Hong Kong Stock Exchange Listing Rules. However, We must obtain the prior approval of the Hong Kong Stock Exchange to engage in some of these transactions and may also be required to obtain the prior approval of our independent directors and our independent shareholders. If we do not obtain these approvals, we may not be allowed to execute these transactions and our business operations and financial condition could be adversely affected. Under current PRC law, CNOOC has the exclusive right to enter into production sharing contracts with foreign oil and gas companies for petroleum exploration and production offshore China. CNOOC has undertaken to us that it will transfer all of its rights and obligations under any new production sharing contracts to us, except those relating to its administrative functions. PRC law restricts us from contracting directly with foreign enterprises for these purposes without CNOOC. The interests of CNOOC in entering into production sharing contracts with international oil and gas companies may differ from our interests, especially with respect to the criteria for determining whether, and on what terms, to enter into production sharing contracts. Our future business development may be adversely affected if CNOOC does not enter into new production sharing contracts on terms that are acceptable to us. Our business performance relies heavily on our sales to several major customers and a substantial drop in sales to any of these customers could have a material adverse effect on our results of operations We sell a significant proportion of our production to CNOOC and its affiliates and China Petroleum & Chemical Corporation, or Sinopec. For the years ended December 31, 2003, 2004 and 2005, sales to CNOOC and its affiliates accounted for 20.3%, 25.3% and 38.3%, respectively, of our total operating revenues, while sales to Sinopec accounted for 17.0%, 19.3% and 22.5%, respectively, of our total operating revenues. CNOOC has a controlling interest in us. However, our transactions with CNOOC and its affiliates are on commercial terms and CNOOC does not guarantee our sales volume or profit margin. Sinopec has its own oil and gas fields and has the right to import crude oil directly from the international market. We do not have any long-term sales contracts with CNOOC and its affiliates or Sinopec. Our business, results of operations and financial condition would be adversely affected if either CNOOC and its affiliates or Sinopec significantly reduces their crude oil purchases from us and we cannot find another ready buyer in the international market to purchase our crude oil at comparable prices. The PRC petroleum and natural gas industries are highly competitive and our success depends on several factors We compete in the PRC and international markets for customers, capital financing and business opportunities, including desirable oil and gas prospects. The performance of our competitors may also affect the international market price for comparable crude oil, which in turn would likely affect the price of our crude oil. Our principal competitors in the PRC market are PetroChina and Sinopec. For further details, see "Item 4--Information on the Company--Business Overview--Competition." We are the dominant player in the oil and gas industry offshore China. Currently, we are the only company permitted to engage in oil and gas exploration offshore China in cooperation with foreign oil and gas companies. Any change to PRC law that allows new entrants to conduct oil and gas exploration activities offshore China in cooperation with international oil and gas companies could increase the competition for new oil and gas properties offshore China. CNOOC has undertaken to us that so long as it retains a controlling interest in us and our securities are listed on the Hong Kong Stock Exchange, the New York Stock Exchange or other securities 14 trading systems in other parts of the world, we will have the exclusive right to exercise CNOOC's rights to engage in offshore oil and gas exploration, development, production and sales in the PRC and that it will not compete with us in such business. However, CNOOC's controlling interest in us may not continue in the future and CNOOC's undertaking may be subject to interpretative challenges. See "Item 4--Information on the Company--History and Development--Corporate Structure" and "Item 7--Major Shareholders and Related Party Transactions." Exploration, development and production risks and natural disasters affect our operations and could result in losses that are not covered by insurance Our petroleum exploration, development and production operations are subject to various risks, including pipeline ruptures and spills, fires, explosions, encountering formations with abnormal pressures, blowouts, cratering and natural disasters. Any of these risks could result in loss of hydrocarbons, environmental pollution and other damage to our properties and the properties of operators under production sharing contracts. In addition, we face the risk that we may not discover any economically productive natural gas or oil reservoirs. The costs of drilling, completing and operating wells also are uncertain and are subject to numerous factors beyond our control, including: o weather conditions; o natural disasters; o availability of equipment and services; o equipment shortages and delays; and o lack of adequate transportation facilities. We maintain insurance coverage against some, but not all, potential losses. We do not maintain business interruption insurance for all of our oil and gas fields. We may suffer material losses resulting from uninsurable or uninsured risks or insufficient insurance coverage. For further information on insurance coverage, see "Item 4--Information on the Company--Business Overview--Operating Hazards and Uninsured Risks." Some foreign countries and regions in which we have operations or may have operations in the future may not have diplomatic or trade relations with other countries and may be subject to trade or economic sanctions imposed by such other countries We currently have operations and assets in various foreign countries and regions, including Indonesia, Australia, Canada, Morocco, Nigeria and Myanmar. We may expand our operations into other countries to further enhance our reserve base and diversify our geographic risk profile. While these countries in which we have operations or may have operations in the future may maintain an amicable relationship with China, some of them may not have diplomatic or trade relations with other countries and may be subject to trade or economic sanctions imposed from time to time by such other countries. We will endeavor to limit our investment and scale of operations in these foreign jurisdictions to minimize our exposure, but we cannot assure that the operations and assets that we currently have or in the future may have in foreign countries and regions will not be affected by trade or economic sanctions that may be imposed by other countries due to their deteriorated relations with each other. Our business and results of operations may be adversely affected if such sanctions are imposed and result in interruption of our overseas operations or non-accessibility of our overseas assets for a significant period of time. We are exposed to operating risks in some foreign countries and regions as a result of our acquisition of oil and gas interests located in these regions We have acquired interests in oil and gas properties located in various foreign countries and regions, including Indonesia, Australia, Canada, Morocco, Nigeria and Myanmar. See "Item 4-- 15 Information on the Company--Business Overview--Principal Oil and Gas Regions--Overseas Activity," "--Natural Gas Business--Overseas Activity" and "Item 5--Operating and Financial Review and Prospects--Operating Results--Acquisitions and Overseas Activities." These interests are subject to operating risks in their respective regions, including economic and political risks. Our non-PRC interests are subject to the laws and regulations of these non-PRC jurisdictions respectively, including those relating to the development, production, marketing, pricing, transportation and storage of crude oil and natural gas, taxation and environmental and safety matters. In addition, our overseas operations generally are subject to production sharing arrangements with production sharing partners. As we expand to different countries, we may become exposed to various operating risks in each of these jurisdictions. Our non-PRC interests may be adversely affected by changes in governmental policies or social instability or other political, economic or diplomatic developments in or affecting these foreign nations which are not within our control including, among other things, a change in crude oil or natural gas pricing policy, the risks of war and terrorism, expropriation, nationalization, renegotiation or nullification of existing concessions and contracts, taxation policies, foreign exchange and repatriation restrictions, changing political conditions, foreign exchange rate fluctuations and currency controls. We may not be able to obtain external financing that is acceptable to us for business development purposes From time to time, we may need to procure external debt and equity financing to implement our development plans and fund our other business requirements. Our ability to obtain external financing is subject to various uncertainties, including: o our results of operations, financial condition and cash flows; o the amount of capital that other PRC and Hong Kong entities may seek to raise in the international capital markets; o economic, political and other conditions in the PRC and Hong Kong; o the PRC government's policies relating to foreign currency borrowings; and o conditions in the PRC, Hong Kong and international capital markets. If we are unable to obtain sufficient funding for our operations or development plans, our business, revenues, net income and cash flows could be adversely affected. For additional information on our capital expenditure plans and financing requirements, see "Item 5--Operating and Financial Review and Prospects--Liquidity and Capital Resources." Once we issue debt securities or otherwise incur indebtedness, we become subject to risks that impact the underlying principal of such indebtedness. While all our current debt securities are rated investment grade by rating agencies, we cannot assure that such ratings will not change due to internal or external factors. These factors may be beyond our control. Even if there is no default or event of default on our part, a market perception of an increased likelihood of a default may have a material adverse effect on our outstanding indebtedness as well as on our business operations. You may not be able to assert claims against Arthur Andersen, our independent public accountants for periods prior to 2002, nor may you be able to assert claims against our current independent public accountants for financial statements previously audited by Arthur Andersen On June 6, 2002, we terminated the engagement of Arthur Andersen & Co as our independent public accountants. Prior to that date, Arthur Andersen had audited our financial statements. Our selected historical financial data for the year ended, and as of, December 31, 2001 set forth in "Item 3--Key Information--Selected Financial Data" were based on our financial statements audited by Arthur Andersen. On June 15, 2002, Arthur Andersen was convicted of federal obstruction of justice charges in 16 connection with the U.S. government's investigation of Enron Corporation. On August 31, 2002, Arthur Andersen voluntarily relinquished its licenses to practice public accountancy in all states of the United States, thereby effectively ceasing to exist as a global accounting firm. Accordingly, it may be difficult or impossible for you to assert any claims against, or recover any damages from, Arthur Andersen, in respect of this annual report, including in respect of the financial statements previously audited by Arthur Andersen. Moreover, our current independent public accountants, Ernst & Young, have not reaudited the financial statements previously audited by Arthur Andersen. Therefore, it is highly unlikely that you will be able to assert claims against, or recover any damages from, Ernst & Young, in respect of the financial statements that were previously audited by Arthur Andersen. Risks relating to the PRC petroleum industry A change in PRC petroleum industry regulations could have an adverse effect on our operations The PRC government exercises control over the PRC petroleum industry, including with respect to licensing, exploration, production, distribution, pricing, taxation, imports and exports and allocation of various resources. In the past, we have benefited from various favorable PRC government policies, laws and regulations that have been enacted to encourage the development of the offshore petroleum industry. See "Item 4--Information on the Company--Regulatory Framework--Special Policies Applicable to the Offshore Petroleum Industry in China." We cannot assure that the legal regime affecting our businesses will remain substantially unchanged or that we will continue to benefit from favorable PRC government policies. In addition, existing PRC regulations require us to apply for and obtain various PRC government licenses and other approvals, including in some cases approvals for amendments and extensions of existing licenses and approvals, to conduct exploration and development activities offshore China. If we are unable to obtain any necessary approvals, our reserves and production would be adversely affected. See "Item 4--Information on the Company--Regulatory Framework." Increasing competition from foreign companies as a result of China's entry into the World Trade Organization may adversely affect our business Effective December 11, 2001, the PRC became a member of the World Trade Organization, or WTO. China's WTO commitments require it, within five years from the date of China's accession to the WTO, to lift restrictions that prohibit foreign companies from directly selling crude and processed oil in China. The sale of natural and liquefied petroleum gas is not specifically dealt with under China's market-access commitments relating to distribution services (as is the case with crude and processed oil). On April 6, 2004, the PRC Ministry of Commerce promulgated the Measures for the Administration on Foreign Investment in Commercial Fields, which generally allow foreign companies, through foreign-invested enterprises, to engage in retail and wholesale businesses other than those subject to special administration by the PRC government such as direct sale of crude and processed oil in China. The lifting of the restrictions on distribution of natural liquefied petroleum gas and the subsequent lifting of the restrictions on distribution of crude and processed oil in accordance with China's WTO commitments may increase competition and may adversely affect our business. We may be penalized if we fail to comply with existing or future environmental laws and regulations Our business is subject to environmental protection laws and regulations in the PRC, as well as other jurisdictions, which, among other things: o impose fees for the discharge of waste substances; o require the payment of fines and damages for serious environmental pollution; and 17 o provide that the government may, at its discretion, close or suspend any facility which fails to comply with orders requiring it to cease or cure operations causing environmental damage. We believe that all of our facilities and operations are in material compliance with the requirements of the relevant environmental protection laws and regulations. However, amendment of existing laws or regulations may impose additional or more stringent requirements. In addition, our compliance with such laws or regulations may require us to incur significant capital expenditures or other obligations or liabilities, which could create a substantial financial burden on us. For a further discussion of the environmental regulations, particularly those in the PRC, see "Item 4--Information on the Company--Business Overview--Environmental Regulation." Risks relating to the PRC PRC economic and political conditions may adversely affect our operations Most of our businesses, assets and operations are located in the PRC. The economic system of the PRC differs from the economies of most developed countries in many respects, including: o government investment; o level of development; o control of capital investment; o control of foreign exchange; and o allocation of resources. The economy of the PRC has been undergoing a transformation from a planned economy to a market-oriented economy. In recent years the PRC government has implemented economic reform measures emphasizing decentralization, utilization of market forces in the development of the PRC economy and a higher level of management autonomy. These economic reform measures have and will continue to subject our businesses to some uncertainty. In the future, our operating results could be adversely affected by changes to the laws and regulations that govern our industry and changes in the PRC political and economic systems. The PRC economy has experienced significant growth since 1978, but the growth has been uneven both geographically and among various sectors of the economy. The PRC government has implemented various policies from time to time to restrain the rate of such economic growth, control inflation and otherwise regulate economic expansion. In addition, the PRC government has attempted to control inflation by controlling the prices of basic commodities. Severe measures or other actions by the PRC government, such as placing additional controls on prices of petroleum and petroleum products, could restrict our business operations and adversely affect our financial position. Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition A portion of our Renminbi revenue may need to be converted into other currencies by our wholly owned principal operating subsidiary in the PRC to meet our foreign currency obligations. We have substantial requirements for foreign currency, including: o debt service on foreign currency denominated debt; o overseas acquisitions of oil and gas properties; o purchases of imported equipment; and 18 o payment of dividends declared in respect of shares held by international investors. Our wholly owned subsidiary in the PRC may undertake current account foreign exchange transactions without prior approval from the State Administration for Foreign Exchange. It has access to current account foreign exchange so long as it can produce commercial documents evidencing such transactions and provided that they are processed through certain banks in China. Foreign exchange transactions under the capital account, including principal payments with respect to foreign currency denominated obligations, will be subject to the registration requirements of the State Administration for Foreign Exchange. The value of the Renminbi against Hong Kong dollar, U.S. dollar and other currencies fluctuates and is affected by, among other things, changes in China's political and economic conditions. Since 1994, the conversion of Renminbi into foreign currencies, including Hong Kong and U.S. dollars, has been based on rates set by the People's Bank of China. The official exchange rate for the conversion of Renminbi into U.S. dollar has generally been stable during the past 10 years. On July 21, 2005, China reformed its foreign exchange regime by moving into a managed floating exchange rate system based on market supply and demand with reference to a basket of currencies. Renminbi would no longer be pegged to the U.S. dollar. From that day to December 31, 2005, Renminbi appreciated about 2.5% against the U.S. dollar. Changes in the PRC government's currency policies may lead to further fluctuations in the exchange rates for the conversion of Renminbi into foreign currencies which could have an uncertain effect on our business and operating results. For further information on foreign exchange risks, foreign exchange rates and hedging activities, see "Item 3--Key Information--Selected Financial Data" and "Item 11--Qualitative and Quantitative Disclosure about Market Risk." However, we may be unable to hedge our exposure to foreign currencies fully and future Renminbi exchange rate movements could adversely affect our results of operations and financial condition. Since we receive substantially all of our revenues and express our profits in Renminbi, any devaluation of the Renminbi may also materially and adversely affect the value of, and any dividends payable on our shares and American depositary shares in foreign currency terms. Certain legal restrictions on dividend distribution may have a material adverse effect on our cash flows We are a holding company. Our exploration, development, production and sales businesses are owned and conducted through various wholly owned subsidiaries, including CNOOC China Limited, our wholly foreign-owned enterprise in the PRC. Accordingly, our future cash flows will consist principally of dividends from our subsidiaries. The subsidiaries' ability to pay dividends to us is subject to PRC regulations, including restriction that companies may pay dividends only out of net income determined in accordance with PRC accounting standards and regulations. In addition, under PRC laws, CNOOC China Limited is required to allocate at least 10% of its net profit to a reserve fund until the balance of the fund has reached 50% of its registered capital. Such reserve is not distributable as cash dividends. Therefore, there is a risk that we could not maintain sufficient cash flows due to these restrictions on dividend distribution. The interpretation and enforcement of PRC laws and regulations is subject to some uncertainty The PRC legal system is based on statutory law. Under this system, prior court decisions may be referred to but are not binding. Since 1979, the PRC government has been developing a comprehensive system of commercial laws and considerable progress has been made in the promulgation of laws and regulations dealing with economic matters, such as corporate organization and governance, foreign investments, commerce, taxation and trade. Because these laws, regulations and legal requirements are relatively new, and because of the limited volume of published cases and judicial interpretations and the non-binding nature of prior court decisions, the interpretation and enforcement of these laws, regulations and legal requirements involve some uncertainty. The PRC government underwent substantial reforms after the National People's Congress meeting in March 2003. The PRC government has reiterated its policy of furthering reforms in the 19 socialist market economy. No assurance can be given that these changes will not have an adverse effect on business conditions in China generally or on our business in particular. Risks relating to our ADSs and shares Additional shares or ADSs eligible for public sale could adversely affect the price of our shares or ADSs Sales, or the real or perceived possibility of sales, of a significant number of additional shares in the public market could adversely affect prevailing market prices for our shares and ADSs. As of June 6, 2006, CNOOC, through its wholly owned subsidiaries, CNOOC (BVI) Limited and Overseas Oil & Gas Corporation Ltd., held approximately 66.41% of our shares and the rest of our shares were held by public investors, including institutional and corporate investors. We cannot predict the effect, if any, that sales of our shares, including sales of large positions held by institutional and corporate investors, or the availability of our shares for future sale, will have on the market price of our shares or ADSs. ITEM 4. INFORMATION ON THE COMPANY A. HISTORY AND DEVELOPMENT Our legal and commercial name is CNOOC Limited. We were incorporated with limited liability on August 20, 1999 in Hong Kong under the Companies Ordinance of Hong Kong. Our business registration number in Hong Kong is 685974. Under the third section of our Memorandum of Association, we may do anything which we are permitted to do by any enactment or rule of law. Our head office is located at 65th Floor, Bank of China Tower, One Garden Road, Central, Hong Kong, and our telephone number is 852-2213-2500. We have appointed CT Corporation System, 111 Eighth Avenue, New York, New York 10011, as our agent for service of process. The PRC government established CNOOC, our controlling shareholder, as the state-owned offshore petroleum company of China in 1982 under the Regulation of the People's Republic of China on Exploitation of Offshore Petroleum Resources in Cooperation with Foreign Enterprises, whereby CNOOC assumed overall responsibility for the administration and development of PRC offshore petroleum operations with foreign oil and gas companies. Prior to March 2003, CNOOC was regulated and supervised by the State Economic and Trade Commission. Since March 2003, the PRC government has undergone substantial reform. The National Development and Reform Commission has succeeded the State Economic and Trade Commission as the primary coordinator for the petroleum industry. Prior to CNOOC's internal business reorganization in 1999, CNOOC and its various affiliates performed both commercial and administrative functions relating to petroleum exploration and development offshore China, including: o exercising the exclusive right to cooperate with foreign partners in offshore petroleum exploration, development, production and sales activities, and taking participating interests in production sharing contracts; o organizing international bidding for offshore petroleum exploitation; o conducting independent exploration, development, production and sales activities in independently operated oil and gas fields offshore China; o awarding projects to and signing bilateral contracts with foreign partners for offshore petroleum exploitation; o reviewing and confirming appraisal reports and overall development plans required under production sharing contracts; and 20 o obtaining from the PRC government all approvals, permits, licenses, consents and special policies necessary under production sharing contracts. Reorganization Pursuant to CNOOC's internal business reorganization in 1999, CNOOC transferred all of its then and current operational and commercial interests in its offshore petroleum business to us. As a result, we and our subsidiaries are the only vehicle through which CNOOC engages in petroleum exploration, development, production and sales activities both within and outside China. The assets and liabilities primarily relating to the offshore petroleum business that were transferred to us in the reorganization included: o 37 production sharing contracts and one geophysical survey agreement; o 8 independent development and production projects; o a 30% interest in Shanghai Petroleum and Natural Gas Company Limited; o the land use rights to terminal facilities in Nanhai, Weizhou and the western part of the Bohai Bay; and o loans from, and swap agreements with, various PRC and foreign banks. In addition, CNOOC transferred 917 employees to us to facilitate the transfer of the oil and natural gas businesses previously operated by CNOOC. CNOOC retained its commercial interests in operations and projects not related to oil and gas exploration and production, including: o a petrochemical project in Huizhou, Guangdong Province; o a fertilizer plant in Hainan Province; and o a liquefied natural gas project in Guangdong Province. CNOOC also retained all of its administrative functions, which it performed prior to the reorganization, including: o organizing international bidding for offshore petroleum exploitation; o awarding projects to and signing bilateral contracts with foreign partners for offshore petroleum exploitation; o approving any extension of the period for the completion of the appraisal work on petroleum discovery under the production sharing contracts; and o submitting the overall development plans, reports of the oil and gas fields and the environmental impact statements related to the production sharing contracts to the PRC governmental authorities. Undertakings CNOOC has undertaken to us that: 21 o we will enjoy the exclusive right to exercise all of CNOOC's commercial and operational rights under the PRC laws and regulations relating to the exploration, development, production and sales of oil and natural gas offshore China; o it will transfer to us all of CNOOC's rights and obligations under any new production sharing contracts and geophysical exploration operations, except those relating to CNOOC's administrative functions; o it will not engage or be interested, directly or indirectly, in oil and natural gas exploration, development, production and sales in or outside the PRC; o we will be able to participate jointly with CNOOC in negotiating new production sharing contracts and to set out our views to CNOOC on the proposed terms of new production sharing contracts; o we will have unlimited and unrestricted access to all data, records, samples and other original data owned by CNOOC relating to oil and natural gas resources; o we will have an option to make investment in liquefied natural gas projects that CNOOC invested or proposed to invest, and CNOOC will at its own expense help us to procure all necessary government approvals needed for our participation in these projects; and o we will have an option to participate in other businesses related to natural gas in which CNOOC invested or proposed to invest, and CNOOC will procure all necessary government approvals needed for our participation in such business. The undertakings from CNOOC will cease to have any effect: o if we become a wholly owned subsidiary of CNOOC; o if our securities cease to be listed on any stock exchange or automated trading system; or o 12 months after CNOOC or any other PRC government-controlled entity ceases to be our controlling shareholder. Organizational Structure CNOOC indirectly owned or controlled an aggregate of approximately 66.41% of our shares as of June 6, 2006. There have been no changes to our corporate structure since such date. Accordingly, CNOOC continues to be able to exercise all the rights of a controlling shareholder, including electing our directors and voting to amend our articles of association. Although CNOOC has retained a controlling interest in us, the management of our business will be our directors' responsibility. The following chart sets forth our controlling entities and our principal subsidiaries as of June 6, 2006. 22 -------------------------- China National Offshore Oil Corporation (PRC) -------------------------- | | 100% | -------------------------- Overseas Oil & Gas Corporation, Ltd(1) (Bermuda) -------------------------- | | 100% | -------------------------- CNOOC (BVI) Limited (British Virgin Islands) -------------------------- -------------------------- | Public Shareholders and | Corporate Investors \ | 66.41% \ 33.59% | -------------------------- \ | \ -------------------------- \ CNOOC Limited \ (Hong Kong) -------------------------- | | | ---------------------------------------------------------------------------------------------- | | | | | 100% | 100% | 100% | 100% | | | | -------------------------- -------------------------- -------------------------- -------------------------- CNOOC China Offshore Oil Finance International CNOOC China (Singapore) Subsidiaries(5) Limited(2) Limited(3) International Pte.

These finance companies are our wholly owned subsidiaries with our company as their sole corporate director. Capital Expenditures Our capital expenditures in 2003, 2004 and 2005 amounted to Rmb 12,372.5 million, Rmb 18,622.0 million and Rmb 17,469.5 million (US$2,164.7 million) , respectively. For 2006, we have budgeted approximately US$3.08 billion for capital expenditures, approximately US$316.3 million of which is budgeted for general exploration activities offshore China and approximately US$1,860.1 million is budgeted for development activities offshore China. We expect to fund our capital expenditures with our cash flows from operations and our borrowings. For further details about our capital expenditures, see "Item 5--Operating and Financial Review and Prospects--Liquidity and Capital Resources--Capital Expenditures and Investments." B. BUSINESS OVERVIEW Overview We are an oil and gas company engaged in the exploration, development and production of crude oil and natural gas primarily offshore China. We are the dominant producer of crude oil and natural gas offshore China and the only company permitted to conduct exploration and production activities with foreign oil and gas companies offshore China. As of December 31, 2005, we had estimated net proved reserves of 2,362.6 million BOE, comprised of 1,457.4 million barrels of crude oil and condensate and 5,430.9 billion cubic feet of natural gas. For 2005, our net production averaged 356,868 barrels per day of 23 crude oil, condensate and natural gas liquids and 389.6 million cubic feet per day of natural gas, which together totaled 424,108 BOE per day. Our net proved reserves increased from 1,787.1 million BOE as of December 31, 2001 to 2,362.6 million BOE as of December 31, 2005 which represents a compound annual growth rate of 7.2%. Based on net proved reserves, we are one of the largest independent oil and gas exploration and production companies in the world. In the petroleum industry, an "independent" company owns oil and gas reserves independently of other downstream assets, such as refining and marketing assets, whereas an integrated company owns downstream assets in addition to oil and gas reserves. As of December 31, 2005, approximately 50.9% of our net proved reserves were classified as net proved undeveloped. We plan to spend US$1,860.1 million developing our reserves primarily offshore China and US$316.3 million for exploration primarily offshore China in 2006. We conduct exploration, development, production and sale activities through both independent operations and production sharing contracts with foreign partners. We have added to our reserves in recent years primarily through our independent operations. As of December 31, 2005, independent properties accounted for 61.9% of our total net proved reserves and independent net proved undeveloped reserves accounted for 67.2% of our total net proved undeveloped reserves. We are the operator of all of our independent producing properties. For the year ended December 31, 2005, production from our independent properties accounted for 45.5% of our total net production. Our controlling shareholder, CNOOC, has the exclusive right to enter into contracts with international oil and gas companies to conduct exploration and production activities offshore China. Under these production sharing contracts, we have the sole right to acquire, at no cost, participating interests in any successful discovery offshore China made by our foreign partners. Our foreign partners can recover their exploration costs under the production sharing contracts only if a commercially viable discovery is made. As of December 31, 2005, we had approximately 28 foreign partners under our existing production sharing contracts offshore China, all of which are international oil and gas companies, including Agip, BP, Burlington Resources, Chevron, ConocoPhillips, Devon Energy, Husky, Kerr-McGee, Newfield Exploration and Royal Dutch Shell. As of December 31, 2005, we were a party to 34 production sharing contracts offshore China. We are currently the operator or joint operator of most of the properties developed under our production sharing contracts. Natural gas is becoming an increasingly important part of our business strategy because of rapidly growing domestic demand. In view of increasing demand for natural gas, we have continued to develop our natural gas reserves and invested in liquefied natural gas related upstream projects outside the PRC. We continue to explore for natural gas and develop natural gas properties. We have acquired interests in gas reserves located in Tangguh, Indonesia and the North West Shelf of Australia. In addition, CNOOC, our controlling shareholder, has granted us an option to invest in liquefied natural gas projects or other natural gas related business in which CNOOC invested or proposed to invest. The terms of this option require us, if we exercise the option, to reimburse CNOOC for any contribution CNOOC has made with respect to the facility together with interest calculated at the prevailing market rate. Competitive Strengths We believe that our historical success and future prospects are directly related to a combination of our strengths, including the following: o large proved reserve base with significant exploitation opportunities; o sizable operating areas with demonstrated exploration potential; o successful independent exploration and development record; o competitive cost structure; o reduced risks and access to capital and technology through production sharing contracts; 24 o strategic position in China's growing natural gas markets; and o experienced management team. Large proved reserve base with significant exploitation opportunities Based on net proved reserves as of December 31, 2005 and average net daily production for the year ended December 31, 2005, we had a reserve-to-production ratio of 15.3 years. As of December 31, 2005, approximately 50.9% of our net proved reserves were classified as net proved undeveloped. We expect our production to grow significantly as these undeveloped properties begin production. Sizable operating area with demonstrated exploration potential The offshore China exploration area is approximately 1.3 million square kilometers in size, about twice as large as the U.S. Gulf of Mexico exploration area. Only limited exploration has been conducted in Western South China Sea and East China Sea. Since CNOOC's inception in 1982 to the end of 2005, a total of 820 exploration wells have been drilled offshore China, including 526 wildcat wells with a success rate of approximately 35%. During the past five years ended December 31, 2005, we made 31 discoveries and foreign partners announced 17 discoveries offshore China. Successful independent exploration and development record. From the inception of CNOOC in 1982 to December 31, 2005, we achieved a success rate of approximately 44% on our 237 offshore China independent wildcat wells, while our foreign partners achieved a success rate of approximately 28% on their 289 offshore China wildcat wells. As of December 31, 2005, independent properties accounted for 61.9% of our total net proved reserves and independent net proved undeveloped reserves accounted for 67.2% of our total net proved undeveloped reserves. In 2005, we completed four of our major independent development projects on time and under budget. Competitive cost structure For the year ended December 31, 2005, our total offshore China lifting costs were US$6.34 per BOE. Total lifting costs for independent operations offshore China were US$5.86 per BOE during the same period. Lifting costs consist of operating expenses and production taxes. We have kept our offshore China lifting costs low through various measures including more efficient use of existing offshore facilities, the linking of employee bonuses to cost reduction and the adoption of new technology in our operations. We believe that such cost structure allows us to compete effectively even in a low crude oil price environment. Reduced risks and access to capital and technology through production sharing contracts Production sharing contracts help us minimize our offshore China finding costs, exploration risks and capital requirements because our foreign partners are responsible for all costs associated with exploration. Our foreign partners recover their exploration costs only if a commercially viable discovery is made. Strategic position in China's growing natural gas markets The proximity of our natural gas reserves to the major demand areas in the coastal regions of China provides us with a competitive advantage over other natural gas suppliers in China, whose natural gas reserves are located primarily in northwest and southwest China. We have natural gas fields near many of China's rapidly growing coastal areas, including Hong Kong, Shanghai and Guangzhou. We have also acquired interests in gas reserves located in Tangguh, Indonesia and the North West Shelf of Australia. In addition, CNOOC has granted us an option to invest in liquefied natural gas projects or other natural gas related businesses in the PRC in which CNOOC invested or proposed to invest. For further information, see "--Natural Gas Business." 25 Experienced management team Our senior management team has extensive experience in the oil and gas industry, and most of our executives have been with the CNOOC group since its inception in 1982. We evolved from a company heavily reliant on production sharing contracts with foreign partners to a company with a balance of both independent and production sharing contract operations. Our management team and staff have had the opportunity to work closely with foreign partners both within and outside China. We have implemented international management practices including incentive compensation schemes for our employees. In addition, we have adopted share option schemes for our employees. See "Item 6--Directors, Senior Management and Employees--Share Ownership." Business Strategy We intend to continue expanding our oil and gas exploration and production activities and, where appropriate, to continue making strategic investments in natural gas businesses. While our expansion strategy will continue to focus primarily on offshore China, we may also consider overseas acquisition opportunities that may be presented to us. The principal components of our strategy are as follows: o increase production primarily through the development of our net proved undeveloped reserves; o add to our reserves through independent exploration and production sharing contracts; o capitalize on the growing demand for natural gas in China; o selectively pursue acquisitions to ensure long-term production growth, geographical reserves risk diversification, and to further our natural gas strategy; o maintain operational efficiency and low production costs; and o maintain financial flexibility through prudent financial practices. Increase production primarily through the development of our net proved undeveloped reserves As of December 31, 2005, approximately 50.9 % of our proved reserves were classified as net proved undeveloped, which gives us the opportunity to achieve substantial production growth even without additional reserve discoveries, assuming that we will be able to develop these reserves more quickly than we deplete our currently producing reserves. We are currently undertaking a number of large development projects located primarily in the Bohai Bay and the Western South China Sea, which we expect to substantially increase production. We plan to spend approximately US$1,860.1 million in 2006 to develop our net proved undeveloped reserves offshore China. We also plan to spend approximately US$373.1 million to develop our overseas reserves in 2006. Add to our reserves through independent exploration and production sharing contracts We plan to concentrate our independent exploration efforts in existing operating areas. We plan to spend approximately US$457.8 million in 2006 on exploration activities. We plan to increase independent exploration efforts while continuing to enter into production sharing contracts with foreign partners to lower capital requirements and exploration risks. In 2006, we plan to drill approximately 67 exploration wells, and acquire independently approximately 25,300 kilometers and 4,050 square kilometers of 2D seismic data and 3D seismic data, respectively. Our foreign partners under existing production sharing contracts plan to drill approximately 22 exploration wells, and acquire approximately 13,200 kilometers and 5,320 square kilometers of 2D seismic data and 3D seismic data, respectively, in 2006. Capitalize on the growing demand for natural gas in China 26 We plan to capitalize on the growth potential of the PRC natural gas market through the following initiatives: o continue to develop natural gas fields and focus independent exploration efforts on natural gas; o evaluate whether to exercise the options to invest in CNOOC's liquefied natural gas projects in China; and o evaluate investment opportunities in related natural gas businesses that will help develop markets for our natural gas production. To the extent we invest in businesses and geographic areas where we have limited experience and expertise, we plan to structure our investments as alliances or partnerships with parties possessing the relevant experience and expertise. Selectively pursue acquisitions to ensure long-term production growth, geographical reserves risk diversification, and to further our natural gas strategy We plan to make selective acquisitions that will meet one or more of our strategic objectives of enhancing our production profile, diversifying our reserve base and geographic risk profile and furthering our natural gas strategy. In addition, we evaluate acquisition opportunities based on our expected economic return criteria. In 2004 and 2005, we, Golden Aaron Pte. Ltd. and China Global Construction Limited. formed a joint venture and entered into six production sharing contracts with Myanmar Oil and Gas Enterprise. We act as the operator under these production sharing contracts. In early 2005, through our wholly owned subsidiary CNOOC Canada Limited, we acquired a 16.69% interest in MEG Energy Corp. at a consideration of 150 million Canadian dollars. In April 2006, we completed the acquisition of a 45% working interest in an offshore oil-mining license "OML 130" in Nigeria for a cash consideration of US$2.268 billion. On April 28, 2006, through our wholly-owned subsidiary CNOOC Africa Limited, we signed production sharing contracts for six blocks with a total area of 115,343 square kilometers in Kenya. We are continuously implementing our natural gas strategy. In April, 2006, we signed Farm-in Agreements with BHP Billiton Limited and Kerr-McGee Australia Exploration and Production Pty Ltd through our subsidiary, CNOOC Australia E&P Pty Ltd, and obtained a 25% interest in four Exploration Permits in the Outer Browse Basin of Australia. We believe these upstream participation will enhance our natural gas strategy as well as provide us with access to other gas-rich basins for further growth opportunities. Maintain operational efficiency and low production costs We will continue to maintain our low cost structure and operational efficiency through the following initiatives: o Apply up-to-date drilling, production and offshore engineering technology to our operations through our oilfield service providers. This technology includes long-range extension wells, multilateral wells, advanced formation testing, multi-phase transmission, monolayer pipeline and subsea technology, minimal structure techniques and suction foundation technology; o Proactively manage service contracts and cooperate with our oilfield service providers to improve exploration efficiency and reduce exploration costs. This measure includes using operational techniques such as cluster drilling, which reduces drilling time by one-third and lowers the related costs by up to 40%; and o Maintain high production volume levels on an individual well basis and increase the productivity of producing wells. 27 Maintain financial flexibility through prudent financial practices Currently, we have a strong financial profile with a low leverage ratio. We intend to maintain our financial strength by managing key measures such as capital expenditures, cash flows and fixed charge coverage. We intend to actively manage our accounts receivable and inventory positions to enhance liquidity and improve profitability. We will continue to monitor our foreign currency denominated debt and to minimize our exposure to foreign exchange rate fluctuations. Selected Operating and Reserves Data The following table sets forth our operating data and our net proved reserves as of the time and for the periods indicated.

Our finding and development costs per BOE reported in prior years was calculated by dividing the net reserve change for each reporting period (excluding production and sales) into the costs incurred for the period, as reported in the "Costs Incurred" disclosure required by Statement of Financial accounting Standards No. 69, "Disclosures about Oil and Gas Producing Activities." Due to the timing of the related costs incurred to find and develop such proved reserves, this often includes quantities of proved reserves for which a majority of the costs of development have not yet been incurred. Conversely, it also often includes costs to develop proved reserves that had been added in earlier years. Because it may not necessarily represent total finding and development costs for projects under way or may not be indicative of expected future finding and development costs, we discontinued reporting such information. At our request, Ryder Scott Company, an independent petroleum engineering consulting company, carried out an independent evaluation of the reserves of selected properties as of December 31, 2003, 2004 and 2005. For further information regarding our reserves, see "Item 3--Key Information--Risk Factors--Risks relating to our business--The oil and gas reserve estimates in this annual report may require substantial revision as a result of future drilling, testing and production" and "--Oil and Natural Gas Reserves." 28 The following table sets forth summary information with respect to our estimated net proved reserves of crude oil and natural gas as of the dates indicated.

and Production Summary We currently conduct exploration, development and production activities primarily in four areas offshore China: o the Bohai Bay; o the Western South China Sea; o the Eastern South China Sea; and o the East China Sea. 31 [GRAPHIC OMITTED] In addition, we hold several equity interests in oil and gas properties in foreign countries and regions including Indonesia, Australia, Canada, Morocco, Nigeria and Myanmar. See "--Overseas Activity," "--Natural Gas Business--Overseas Activity" and "Item 5--Operating and Financial Review and Prospects--Operating Results--Acquisitions and Overseas Activities." As of December 31, 2005, we had estimated net proved reserves of 2,362.6 million BOE, comprised of 1,457.4 million barrels of crude oil and condensate and 5,430.9 billion cubic feet of natural gas. As of December 31, 2005, we had interests in 41 producing properties and 49 properties under development and appraisal offshore China. In 2005, seven properties offshore China commenced production. For 2005, net production averaged 356,868 barrels per day of crude oil, condensate and natural gas liquids and 389.6 million cubic feet per day of natural gas, which together totaled 424,108 BOE per day, representing a 10.9% increase over the annual average daily production for 2004. We conduct our exploration, development and production activities independently as well as through production sharing contracts with foreign partners. A production sharing contract contains provisions regarding the exploration, development, production and operation of an oil and gas field and the formula through which foreign partners may recover exploration, development and production costs and share in the production after the successful development of petroleum reserves. See "--Production Sharing Contracts--Offshore China" for a detailed discussion of these arrangements. 32 We also conduct exploration efforts through geophysical survey agreements with foreign companies. These geophysical survey agreements allow international oil and gas companies to conduct geophysical studies before deciding whether to negotiate a production sharing contract with CNOOC. If a foreign partner decides to enter into a production sharing contract with CNOOC, the costs and expenses that the foreign partner incurs in conducting geophysical exploration may be recovered during the production period by the foreign partner, subject to our confirmation. See "--Geophysical Survey Agreements" for a detailed discussion of these arrangements. As of December 31, 2005, we were not a party to any geophysical survey agreements, although we may enter into such agreements in the future. The offshore China exploration area is approximately 1.3 million square kilometers in size. We currently have rights to operate independently or in conjunction with international oil and gas companies in 134 exploration blocks covering approximately 627,271 square kilometers. We have access to 902,476 kilometers of 2D seismic data and 45,217 square kilometers of 3D seismic data. From the beginning of CNOOC's operations in 1982 to December 31, 2005, a total of 820 exploration wells have been drilled, including 526 wildcat wells, with a success rate of approximately 35%. During this period we achieved a success rate of approximately 44% on 237 independent exploration wildcat wells, while our foreign partners achieved a success rate of approximately 28% on their 289 exploration wildcat wells. Oil and Natural Gas Reserves We have a large base of net proved undeveloped reserves as a result of our exploration successes. As of December 31, 2005, approximately 50.9% of our net proved reserves were classified as net proved undeveloped. We are undertaking a number of large development projects located primarily in the Bohai Bay and the Western South China Sea and expect these projects to substantially increase our production. Our "net proved reserves" consist of our percentage interest in reserves, including our 100% interest in the independent oil and gas properties and our participating interest in the properties covered under the production sharing contracts in PRC, less: (a) an adjustment for our share of royalties payable by us to the PRC government and our participating interest in share oil payable to the PRC government under the production sharing contracts, and (b) an adjustment for production allocable to foreign partners under the PRC production sharing contracts as reimbursement for exploration expenses attributable to our participating interest; and plus (i) our 5.3% participating interest in North West Shelf Project in Australia, and (ii) our participating interest in the properties covered under the production sharing contracts in Indonesia less an adjustment for share oil attributable to the Indonesian government and the domestic market obligation. Net proved reserves do not include any deduction for production taxes, which are included in our operating expenses. Net production is calculated in the same way as net proved reserves. We explore and develop our reserves offshore China under exploration and production licenses granted by the PRC government. The PRC government generally grants exploration licenses for individual blocks while production licenses generally are granted for individual fields. All of our proved reserves are under production licenses granted by the PRC government. At our request, Ryder Scott Company, an independent petroleum engineering consulting company, evaluated our selected properties as of December 31, 2003, 2004 and 2005. For further information regarding our reserves, see "Item 3--Key Information--Risk Factors--Risks relating to our business--The oil and gas reserves data in this annual report may require substantial revisions as a result of future drilling, testing and production." The following tables set forth net proved crude oil reserves, net proved natural gas reserves and total net proved reserves, as of the dates indicated, for our independent and production sharing contract operations in each of our operating areas. 33 Total Net Proved Crude Oil Reserves (mmbbls) As of December 31, As of December 31, 2005 -------------------- ---------------------------------------------- 2003 2004 Developed Undeveloped Total ------- ------- --------- ----------- ------- Offshore China Independent Bohai Bay.......................... 474.3 487.8 285.3 213.6 498.9 Western South China Sea............ 135.2 147.6 43.2 125.8 169.0 Eastern South China Sea............ 56.6 69.1 39.6 56.9 96.5 East China Sea..................... 4.6 21.5 2.8 18.4 21.2 ------- ------- --------- ----------- ------- Total......................... 670.8 726.0 370.9 414.7 785.6 Production Sharing Contracts Bohai Bay.......................... 516.1 486.8 166.7 254.6 421.3 Western South China Sea............ 38.5 42.0 34.5 2.3 36.8 Eastern South China Sea............ 98.1 98.8 72.4 42.3 114.7 East China Sea..................... 9.3 -- -- -- -- ------- ------- --------- ----------- ------- Total......................... 662.0 627.6 273.6 299.2 572.8 Combined Bohai Bay.......................... 990.4 974.6 452.0 468.2 920.2 Western South China Sea............ 173.7 189.7 77.6 128.1 205.7 Eastern South China Sea............ 154.8 168.0 112.0 99.2 211.2 East China Sea..................... 13.9 21.5 2.8 18.4 21.2 ------- ------- --------- ----------- ------- Total......................... 1,332.7 1,353.8 644.4 713.9 1,358.3 Overseas(1) Indonesia.......................... 103.4 101.9 62.7 11.0 73.7 North West Shelf, Australia........ -- -- 14.4 11.0 25.4 ------- ------- --------- ----------- ------- Total.............................. 103.4 101.9 77.1 22.0 99.1 Total.................................... 1,436.1 1,455.6 721.5 735.9 1,457.4 ======= ======= ========= =========== ======= --------- (1) As of December 31, 2005, our net proved reserves attributable to overseas operations were derived mainly from Indonesia and Australia.

The East China Sea is approximately 339,580 square kilometers in size and is located east of Shanghai. As of December 31, 2005, we had rights to operate, independently or in conjunction with international oil and gas companies, in 47 blocks (excluding the Pinghu block) covering approximately 209,816 square kilometers of the total East China Sea. On August 19, 2003, CNOOC, Sinopec, Pecten Orient Company of the United States (a subsidiary company of Shell) and Unocal reached an agreement to explore, develop and market natural gas, oil and condensate in Xihu Trough, East China Sea. Under the agreement CNOOC owned 30% of the project and accordingly, we acquired a 30% working interest in the project from CNOOC. In September 2004, Pecten Orient and Unocal exited the project and as a result, our working interest in the Xihu Trough project was increased to 50%. The project comprises three exploration and two development contract areas of the Xihu Trough covering approximately 22,000 square kilometers. The first development under the contracts will be in the Chunxiao development area, which is expected to 42 come on stream in the first half of 2006. The total block area of the Xihu Trough is approximately 59,565 square kilometers. Typical water depths in this region are approximately 90 meters and the crude oil and condensate are of light gravity. As of December 31, 2005, our net proved reserves in the Xihu Trough were 18.1 million barrels of crude oil and condensate and 365.7 billion cubic feet of natural gas, totaling 79.1 million BOE and representing 3.7% of our total net proved reserves. We are the operator of the project. In 2005, we and our foreign partners drilled no wells in this area.

We intend to exploit our natural gas reserves to meet rapidly growing demand in the PRC for natural gas. In light of increasing demand for natural gas in the PRC, we have made strategic investments in liquefied natural gas projects outside the PRC and may continue to do so in the future. PRC Activity CNOOC, our controlling shareholder, has granted us an option to invest in liquefied natural gas projects or other natural gas related businesses in which CNOOC has invested or proposed to invest. The terms of this option require us, if we exercise the option, to reimburse CNOOC for any contribution CNOOC has made with respect to the facility together with interest calculated at the prevailing market rate. CNOOC's major liquefied natural gas projects in the PRC include: Guangdong LNG Facility. CNOOC is currently engaged in a project to build China's first proposed liquefied natural gas import facility in Guangdong Province in southern China. We have not entered into any negotiations with CNOOC on the detailed terms under which we may exercise our option to acquire CNOOC's interest in this facility. CNOOC has committed to take a 33% ownership interest in the project. Other partners include Hong Kong Electric Holding Company and Hong Kong & China Gas Company Limited, each committed to 3% ownership interests, and five customers of the proposed facility who have collectively committed to a 31% ownership interest. Through a competitive selection process, BP Global Investment Limited was selected as the foreign partner to take the remaining 30% interest in the project. The project involves the construction of a receiving terminal with capacity of 3.7 million tonnes per year and a 380-kilometer trunk line. Project construction began in the third quarter of 2003. The facility is scheduled to commence operations in 2006. Fujian Development. In October 2001, CNOOC signed an agreement with the Fujian provincial government on natural gas market development in Fujian Province. The agreement provides for a joint investment commitment to increase natural gas supply and gas market development in Fujian Province. Both parties are committed to sourcing gas, including liquefied natural gas, from all viable sources, including from offshore production and overseas. The parties also agreed to invest in gas-fired power plants and related infrastructure. The parties contemplate that the Tangguh LNG project in Indonesia will supply liquefied natural gas to this project. In August 2002, CNOOC announced that China's second LNG terminal would be built in Fujian by CNOOC and its partners. CNOOC owns a 60% interest in the 48 project. Construction for the project began in the third quarter of 2003. The project is scheduled to commence operations in 2008. Zhejiang Development. In March 2004, CNOOC signed an agreement with Zhejiang provincial government to jointly develop China's third LNG terminal in Zhejiang. The joint development will include construction of an LNG re-gasification terminal, a gas trunk line and a gas-fired power plant. CNOOC will take a 51% interest in the project, with a Zhejiang government affiliate and a Ningbo city government affiliate taking a 29% interest and a 20% interest, respectively, in the project. Based on current plan and estimate, phase one construction of the project will be completed in 2008. Shanghai LNG Project. In September 2004, CNOOC signed an agreement with a Shanghai municipal government affiliate to build a liquefied natural gas import facility in Shanghai. This project involves the construction of a receiving terminal and a submarine trunk line. Based on current arrangements, CNOOC will take a 45% equity interest in the project, with the Shanghai partner taking the remaining 55% interest. Based on current plan and estimate, phase one construction of the project will be completed in 2008. Overseas Activity On January 1, 2003, we acquired BP Muturi Limited, which owned a 44.0% interest in the Muturi production sharing contract offshore Indonesia, and BP Wiriagar Limited's 42.4% interest in the Wiriagar production sharing contract offshore Indonesia for a consideration of approximately US$275 million. The Muturi production sharing contract and Wiriagar production sharing contract, together with the Berau production sharing contract, make up the Tangguh LNG project. The Tangguh LNG project is a greenfield project located offshore Indonesia and is one of the largest natural gas projects in Asia. On May 12, 2004, we completed our acquisition of an additional 20.767% interest in the Muturi production sharing contract from British Gas International Limited for a consideration of US$105.1 million. As a result, our interest in the Muturi production sharing contract increased to 64.767%. Our interests in these production sharing contracts represent 16.96% of the total reserves and upstream production of the Tangguh LNG project. The remaining interests in the Tangguh LNG project are held by BP Berau, BP Muturi, BP Wiriagar, MI Berau, Nippon, KG Berau, KG Wiriagar and Indonesia Natural Gas Resources Muturi. The partners in the Tangguh LNG project have applied to the Indonesia government to consolidate the three production sharing contracts and expect that BP will serve as the operator for the project. In connection with our acquisition of interests in the Tangguh LNG project, the partners in the Tangguh LNG project entered into a conditional 25-year supply contract to provide up to 2.6 million tonnes of liquefied natural gas per year to a liquefied natural gas terminal project in Fujian Province, China. Supply of liquefied natural gas under this supply contract is expected to begin in 2009. In July 2004, the Tangguh PSC partners signed the LNG sales and purchases agreement("SPA") with POHANG Steel Co to provide up to 0.55 million tonnes per annum ("mtpa") LNG for 20 years. In August 2004, the Tangguh PSC partners signed the LNG SPA with K-Power. Co. Ltd. to provide up to 0.6 mtpa LNG for 20 years. In October 2004, the Tangguh PSC partners signed the LNG SPA with Sempra Energy LNG Marketing Corp. to provide up to 3.615 mtpa LNG for 20 years. Given the proximity of the Tangguh LNG project to many major industrial and commercial areas, we expect the project to secure additional LNG supply contracts in the near future. In May 2003, we signed an agreement with the original North West Shelf project partners to acquire an aggregate interest of 5.3% in the reserves and upstream production of Australia's North West Shelf project for a consideration of US$348 million. We completed this acquisition in December 2004. We booked 125.9 million BOE of gas reserves from this project in 2005. Woodside Petroleum is the operator for the project. Pursuant to the agreement, we also acquired a 25% interest in the China LNG Joint Venture established by the six original partners to supply liquefied natural gas from the North West Shelf project 49 to a liquefied natural gas terminal currently being developed by CNOOC, our controlling shareholder, and various partners in Guangdong Province, China. The terms of this transaction require us to pay the other partners in the North West Shelf project for gas production and processing services provided over the term of the China LNG Joint Venture. We are also required to make an upfront tariff payment of approximately US$180 million in relation to liquefied natural gas processing facilities. The partners of the project signed a 25-year LNG supply agreement in December 2004 to provide liquefied natural gas to the Guangdong liquefied natural gas terminal starting 2006. On October 24, 2003, we entered into an agreement with the joint venture participants of the Gorgon natural gas project in Australia based on a memorandum of understanding, under which we agreed to acquire certain interest in the upstream production and reserves of the Gorgon natural gas project. The memorandum of understanding expired in March 2005. In April, 2006, we signed Farm-in Agreements with BHP Billiton Limited and Kerr-McGee Australia Exploration and Production Pty Ltd through our subsidiary, CNOOC Australia E&P Pty Ltd, and obtained a 25% interest in four Exploration Permits in the Outer Browse Basin of Australia. To the extent we invest in businesses and geographic areas where we have limited experience and expertise, we plan to structure our investments as alliances and partnerships with parties possessing the relevant experience and expertise. Segment Information The following table shows the breakdown of our total consolidated operating revenues for each of the periods indicated and the percentage contribution of each revenue component to our total operating revenues: Year ended December 31, ------------------------------------------------------------------------------ 2003 2004 2005 ------------------- --------------------- ---------------------- Rmb'000 % Rmb'000 % Rmb'000 % ---------- ----- ---------- ----- ---------- ----- Independent operations................... 12,049,054 29.4 16,104,429 29.2 24,419,997 35.2 Production sharing contracts............. 20,231,534 49.4 24,396,521 44.2 38,179,412 55.0 Trading businesses....................... 12,398,661 30.3 18,191,353 32.9 15,901,325 22.9 Unallocated and elimination..............

For the year ended December 31, 2005, approximately 56.1% of our total revenue was contributed by PRC customers. Our overseas activities are mainly conducted in Indonesia, Australia, Myanmar and Nigeria. Sales and Marketing Sales of Offshore Crude Oil We sell crude oil and natural gas to the PRC market through our wholly owned PRC subsidiary, CNOOC China Limited, and sell to the international market through our wholly owned subsidiary, China Offshore Oil (Singapore) International Pte. Ltd., located in Singapore. We submit production and sales plans to the National Development and Reform Commission each year. Based on information provided by China's three crude oil producers, PetroChina, Sinopec and us, the National Development and Reform Commission compiles an overall national plan to coordinate sales. Our sales of crude oil to the international market also require us to obtain export licenses issued by the PRC Ministry of Commerce. Historically, we have been able to obtain all required export licenses. 50 Pricing We price our crude oil with reference to prices for crude oil of comparable quality in the international market, including a premium or discount mutually agreed upon by us and our customers according to market conditions at the time of the sale. Prices are quoted in U.S. dollars, but domestic sales are billed and paid in Renminbi. We currently produce three types of crude oil: Nanhai Light, Medium Grade and Heavy Crude. The table below sets forth the sales and marketing volumes, pricing benchmarks and average realized prices for each of these three types of crude oil for the periods indicated. Year ended December 31, ------------------------------ 2003 2004 2005 -------- -------- -------- Sales and Marketing Volumes (benchmark) (mmbbls)(1) Nanhai Light (APPI(2) Tapis(3))............... 20.4 13.1 18.4 Medium Grade (Daqing OSP(4)).................. 69.6 91.8 85.3 Heavy Crude (APPI(2) Duri(5))................. 60.2 63.9 86.7 Average Realized Prices (US$/bbl)(6) Nanhai Light..................................

Markets and Customers We sell most of our crude oil production in the PRC domestic market. We also sell to customers in South Korea, Japan, the United States and Australia, as well as to crude oil traders in the spot market. For the years ended December 31, 2003, 2004 and 2005, we sold approximately 73.5%, 81.2% and 70.9%, respectively, of our crude oil in the PRC, and exported approximately 26.5%, 18.8% and 29.1%, respectively. Most of our crude oil production sales in the PRC domestic market are to refineries and petrochemical companies that are affiliates of Sinopec, PetroChina and CNOOC, our controlling shareholder. Sales volume to Sinopec has been high historically because most of the PRC refineries and petrochemical companies were affiliates of Sinopec. After the restructuring of the PRC petroleum industry in July 1998, some refineries and petrochemical companies were transferred to PetroChina from Sinopec. For the years ended December 31, 2003, 2004 and 2005, sales to Sinopec were approximately 51 36.8%, 38.4% and 41.9%, respectively, and sales to PetroChina were approximately 7.7%, 7.0% and 5.0%, respectively, of our total crude oil sales in the PRC domestic market. Together these two customers accounted for approximately 44.5%, 45.4% and 46.9%, respectively, of our total crude oil sales in the PRC domestic market. For the same periods, sales to affiliates of CNOOC were approximately 43.9%, 41.2% and 48.0%, respectively, of our total crude oil sales in the PRC domestic market. For further information about our sales to CNOOC-affiliated companies, please see note 27 to our consolidated financial statements attached to this annual report. The following table presents, for the periods indicated, our revenues sourced in the PRC and outside the PRC: Year ended December 31, ---------------------------- 2003 2004 2005 ------ ------ ------ (Rmb in millions, except percentages) Revenues sourced in the PRC................... 25,416 30,453 38,993 Revenues sourced outside the PRC.............. 15,534 24,769 30,463 ------ ------ ------ Total revenues................................ 40,950 55,222 69,456 ====== ====== ====== % of revenues sourced outside the PRC......... 37.9% 44.9% 43.9% Sales Contracts We sign sales contracts with our oil customers for each shipment. Sales contracts are standard form contracts containing ordinary commercial terms such as quality, quantity, price, delivery and payment. All sales are made on free-on-board terms. Some of our customers are required to make payments within 30 days after the shipper takes possession of the crude oil cargo at our delivery points. Some of them are required to make prepayment or provide guarantee letters or letter of credit. As of December 31, 2003, 2004 and 2005, most of our account receivables were aged within six months. During the years ended December 31, 2003, 2004 and 2005, the accounts receivable turnover were approximately 47.5 days, 42.3 days and 32.6 days, respectively. Doubtful accounts provision during the years ended December 31, 2003, 2004 and 2005 were Rmb 1.5 million, nil and nil, respectively. We have a credit control policy, including credit investigation of customers and periodic assessment of credit terms. Sales clerks are directly responsible for liaising with customers on the collection of receivables within the credit terms. We price our crude oil in U.S. dollars. PRC customers are billed and make actual payments in Renminbi based on the exchange rate prevailing at the bill of lading date, while overseas customers are billed and are required to make payments in U.S. dollars within 30 days of the bill of lading date. Sales of Natural Gas from Offshore China Driven by environmental and efficiency concerns, the PRC government is increasingly encouraging residential and industrial use of natural gas to meet primary energy needs. In 1989, in order to encourage natural gas production, the PRC government adopted a favorable royalty treatment, which provides a royalty exemption for natural gas production up to two billion cubic meters (70.6 billion cubic feet or 11.8 million BOE) per year as compared to a royalty exemption available for crude oil production of up to one million tons or approximately seven million BOE per year. The favorable treatment also includes lower royalty rates on incremental increases in natural gas production as compared with the royalty rates for crude oil production. Since 1989, the PRC government has adopted the following sliding scale of royalty payments of up to 3% of the annual gross production of natural gas: 52 Annual gross production Royalty rate Less than 2 billion cubic meters................................. - 2-3.5 billion cubic meters....................................... 1.0% 3.5-5 billion cubic meters....................................... 2.0% Above 5 billion cubic meters..................................... 3.0% We sell a large portion of our offshore China natural gas production to Hong Kong and Hainan Province. In December 1992, Castle Peak Power in Hong Kong signed a long-term gas supply contract under which it agreed to buy from the partners approximately 102.4 billion cubic feet of natural gas per year on a take-or-pay basis until 2015. Gas prices are quoted and paid in U.S. dollars. The payments are made in U.S. dollars on a monthly basis and are reconciled annually. Castle Peak Power purchased approximately 38.4% of our total offshore China natural gas production for the year ended December 31, 2005. We sold the remaining of our total offshore China natural gas production to mainland China customers, including Hainan Fertilizer, Hainan Yangpu Power, Shandong Yantai Zhongshi Gas and Hainan Refinery. The price of gas sold to the PRC market is determined by negotiations between us and the buyers based on market conditions. Contracts typically consist of a base price with provisions for annual or seasonal resets and adjustment formulas which depend on a basket of crude oil prices, inflation and various other factors. Procurement of Services We usually outsource work in connection with the acquisition and processing of seismic data, reservoir studies, well drilling services, wire logging and perforating services and well control and completion service to independent third parties or our connected parties. In the development stage, we normally employ independent third parties for single point mooring and floaring production storage and offloading, or FPSO, services and both independent third parties and CNOOC affiliates for other services by entering into contracts with them. We conduct a bidding process to determine who we employ to construct platforms, terminals and pipelines, to drill production wells and to install offshore production facilities. Both independent third parties and CNOOC affiliates participate in the bidding process. We are closely involved in the design and management of services by contractors and exercise extensive control over their performance, including their costs, schedule, quality and HSE (health, safety, and environment) measures. Competition Domestic Competition The petroleum industry is highly competitive. We compete in the PRC and in international markets for customers as well as capital to finance our exploration, development and production activities. Our principal competitors in the PRC market are PetroChina and Sinopec. We price our crude oil on the basis of comparable crude oil prices in the international market. The majority of our customers for crude oil are refineries affiliated with Sinopec and PetroChina to which we have been selling crude oil, from time to time, since 1982. Based on our dealings with these refineries, we believe that we have established a stable business relationship with them. We are the dominant player in the oil and gas industry offshore China and are the only company permitted to engage in oil and gas exploration and production offshore China in cooperation with foreign parties. We may face increasing competition in the future from other petroleum companies in obtaining new PRC offshore oil and gas properties, or, as a result of changes in current PRC laws or regulations permitting an expansion of existing companies' activities or new entrants into the industry. As part of our business strategy, we intend to expand our natural gas business to meet rapidly increasing domestic demand. Our competitors in the PRC natural gas market are PetroChina and, to a lesser extent, Sinopec. Our principal competitor, PetroChina, is the largest supplier of natural gas in China in terms of volume of natural gas supplied. PetroChina's natural gas business benefits from strong 53 market positions in Beijing, Tianjin, Hebei Province and northern China. We intend to develop related natural gas businesses in China's coastal provinces, where we may face competition from PetroChina and, to a lesser extent, Sinopec. We believe that our extensive natural gas resources base, the proximity of these resources to the markets in China, our relatively advanced technologies and our experienced management team will enable us to compete effectively in the domestic natural gas market. Foreign Competition and the World Trade Organization Imports of crude oil are subject to tariffs, import quotas, handling fees and other restrictions. The PRC government also restricts the availability of foreign exchange with which the imports must be purchased. The combination of tariffs, quotas and restrictions on foreign exchange has, to some extent, limited the competition from imported crude oil. In line with the general progress of its economic reform programs, the PRC government has agreed to reduce import barriers as part of its WTO commitments. As a result of China joining the World Trade Organization as a full member on December 11, 2001, it is required to further reduce its import tariffs and other trade barriers over time, including with respect to certain categories of petroleum and crude oil. Notwithstanding China's WTO related concessions, crude and processed oil remain, for the time being, subject to restrictions on import rights and only certain designated state-owned enterprises may import crude and processed oil. Sinopec, PetroChina and several other domestic companies have received permission to import crude oil on their own. At present, foreign owned or foreign invested entities and other none-state-owned enterprises are subject to certain import quotas. PRC Fiscal Regimes for Offshore Crude Oil and Natural Gas Activities We conduct exploration and production operations either independently or jointly with foreign partners under our production sharing contracts. The PRC government has established different fiscal regimes for crude oil and natural gas production from our independent operations and from our production sharing contracts. Royalties paid to the PRC government are based on our gross production from both independent operations and oil and gas fields under production sharing contracts. The amount of the royalties varies up to 12.5% based on the annual production of the relevant property. The PRC government has provided companies such as ours with a royalty exemption for up to approximately one million tons, or seven million BOE, per year for our crude oil production and for up to 70.6 billion cubic feet, or approximately 11.8 million BOE, per year for our natural gas production. The limits in these exemptions apply to our total production from both independent properties and properties under production sharing contracts. In addition, we pay production taxes to the PRC government equal to 5% of our crude oil and gas produced independently and 5% of our crude oil and gas produced under production sharing contracts. Under our production sharing contracts, production of crude oil and gas is allocated among us, the foreign partners and the PRC government according to a formula contained in the contracts. Under this formula, a percentage of production under our production sharing contracts is allocated to the PRC government as its share oil. For more information about the allocation of production under the production sharing contracts, see "--Production Sharing Contracts--Offshore China--Production Sharing Formula." We cannot give any assurance that the fiscal regime outlined above will not change significantly in the future. Production Sharing Contracts Offshore China When exploration and production operations offshore China are conducted through a production sharing contract, the operator of the oil or gas field must submit a detailed evaluation report upon discovery of petroleum reserves. If such a discovery is determined commercially viable pursuant to the procedures set forth in the production sharing contract, an overall development plan must be submitted to 54 a joint management committee established under the production sharing contract for its review and adoption. After that, the overall development plan must also be submitted to CNOOC. After CNOOC confirms the overall development plan, CNOOC submits it to the National Development and Reform Commission for approval. After receiving the governmental approval, the parties to the production sharing contract may begin the commercial development of the oil and gas field. As part of the reorganization in 1999, CNOOC transferred all of its economic interests and obligations under its then existing production sharing contracts to us and our subsidiaries. It also undertook to transfer its future production sharing contracts to us and our subsidiaries. As of December 31, 2005, we had 34 production sharing contracts. Under PRC law, the negotiation of a production sharing contract is a function that only a state-owned national company, such as CNOOC, may perform. This function cannot be transferred to us because we are a pure commercial entity. Since the reorganization, under the terms of its undertaking with us, CNOOC, after entering into production sharing contracts with international oil and gas companies, is required to assign immediately to us all of its economic interests and obligations under the production sharing contracts. For further details, see "Item 4--Information on the Company--History and Development" and "Item 7--Major Shareholders and Related Party Transactions--Related Party Transactions." New production sharing contracts are entered into between CNOOC and foreign partners primarily through bidding organized by CNOOC and direct negotiation. Bidding Process The bidding process typically involves the following steps: o CNOOC, with the approvals of the PRC government, determines which blocks are open for bidding and prepares geological information packages and bidding documentation for these blocks; o CNOOC invites foreign enterprises to bid; o potential bidders are required to provide information, including estimates of minimum work commitments, exploration costs and percentage of share oil payable to the PRC government; and o CNOOC evaluates each bid and negotiates a production sharing contract with the successful bidder. Under CNOOC's undertaking with us, we may participate with CNOOC in all negotiations of new production sharing contracts. The term of a production sharing contract typically lasts for 30 years and has three distinct phases: o Exploration. The exploration period shall be divided into three phases with three, two and two years for each phase, and may be extended with the consent of CNOOC and the approval of relevant PRC regulatory authorities. During this period, exploratory and appraisal work on the exploration block is conducted in order to discover petroleum and to enable the parties to determine the commercial viability of any petroleum discovery. o Development. The development period begins on the date on which the relevant PRC regulatory authorities approve the overall development plan, which outlines the recoverable reserves and schedule for developing the discovered petroleum reserves. The development phase ends when the design, construction, installation, drilling and related research work for the realization of petroleum production as provided in the overall development plan have been completed. 55 o Production. The production period begins when commercial production commences and usually lasts for 15 years. The production period may be extended upon approval of the PRC government. Minimum Work Commitment Under production sharing contracts that involve exploration activities, the foreign partners must complete a minimum amount of work during the exploration period, generally including: o drilling a minimum number of exploration wells; o producing a fixed amount of seismic data; and o incurring a minimum amount of exploration expenditures. Foreign partners are required to bear all exploration costs during the exploration period. However, such exploration costs can be recovered according to the production sharing formula after commercial discoveries are made and production begins. During the exploration period, foreign partners are required to return 25% of the contract area, excluding the development and production areas, to CNOOC at the end of each phase of the exploration period. At the end of the exploration period, all areas, excluding the development areas, production areas and areas under evaluation, must be returned to CNOOC. Participating Interests Pursuant to production sharing contracts, we have the right to take participating interests in any oil or gas field discovered in the contract area and may exercise this right after the foreign partners have made commercially viable discoveries. The foreign partners retain the remaining participating interests. Production Sharing Formula A chart illustrating the production sharing formula under our production sharing contracts is shown below. Percentage of annual gross production Allocation -------------------------------------------------------------------------------- 5.0% Production tax payable to the PRC government, or VAT(1) 0.0% -- 12.5%(2) Royalty oil payable to the PRC government 50.0% -- 62.5%(2) Cost recovery oil allocated according to the following priority: 1. recovery of current year operating costs by us and foreign partner(s); 2. recovery of earlier exploration costs by foreign partner(s); 3. recovery of development costs by us and foreign partner(s) based on participating interests;(3) and 4. any excess, allocated to the remainder oil. 32.5%(3) Remainder oil allocated according to the following formula: 1. (1-X) multiplied by 32.5% represents share oil payable to the PRC government; and 2. X multiplied by 32.5% represents remainder oil distributed according to each partner's participating interest.(4) --------- (1) The production tax is also referred to as "value-added tax" (VAT) in PRC production sharing contracts. (2) Assumes annual gross production of more than four million metric tons, approximately 30 million barrels of oil. For lower amounts of production, the royalty rate will be lower and the cost recovery will be greater than 50.0% by the amount that the royalty rate is less than 12.5%. 56 (3) The ratio "X" is agreed in each production sharing contract based on commercial considerations and ranges from 8% to 100%. (4) See "--Principal Oil and Gas Regions" for our participating interest percentage in our production sharing contracts. The first 5.0% of the annual gross production is paid to the PRC government as production tax. The PRC government is also entitled to a royalty payment equal to the next 0% to 12.5% of the annual gross production based on the following sliding scale: Royalty Annual gross production of oil(1) rate ------------------------------------------------------------------------------- Less than 1 million tons............................................. 0.0% 1-1.5 million tons................................................... 4.0% 1.5-2.0 million tons................................................. 6.0% 2.0-3.0 million tons................................................. 8.0% 3.0-4.0 million tons................................................. 10.0% Above 4 million tons................................................. 12.5% --------- (1) The sliding scale royalty for natural gas reaches a maximum at 3.0%. Depending on the percentage of the PRC government's royalty payment, an amount equal to the next 50.0% to 62.5% of the annual gross production is allocated to the partners for cost recovery purposes. This amount is allocated according to the following priority schedule: o recovery of operating costs incurred by the partners during the year; o recovery of exploration costs, excluding interest accrued thereon, incurred but not yet recovered by foreign partners during the exploration period; and o recovery of development investments incurred but not yet recovered, and interest accrued in the current year, according to each partner's participating interest. The remaining 32.5% of the annual gross production, which is referred to as the remainder oil, is distributed to each of the PRC government, us and the foreign partners according to a "ratio X" agreed to by CNOOC and the foreign partners in the production sharing contracts. An amount of oil and gas equal to the product of the remainder oil and one minus the "ratio X" is first distributed to the PRC government as share oil. The balance of the remainder oil, which is referred to as the allocable remainder oil, is then distributed to us and the foreign partners based on each party's participating interest. We pay production tax and royalty to the PRC government on a monthly basis for oil and natural gas production. At the end of each month, we calculate the production tax and royalty payable and file this information with the PRC tax bureau for current month payment. We make adjustments for any overpayment or underpayment of production tax and royalty at the end of the year. The foreign partners have the right to either take possession of their allocable remainder oil for sale in the international market, or sell such crude oil to us for resale in the PRC market. Management and Operator Under each production sharing contract, a party will be designated as an operator to undertake the execution of the production sharing contract which includes: o preparing work programs and budgets; o procuring equipment and materials relating to operations; o establishing insurance programs; and o issuing cash-call notices to the parties to the production sharing contract to raise funds. 57 A joint management committee, which usually consists of six or eight persons, is set up under each production sharing contract to perform supervisory functions, and each of us and the foreign partners as a group has the right to appoint an equal number of representatives to form the joint management committee. The chairman of the joint management committee is the chief representative designated by us and the vice chairman is the chief representative designated by the foreign partners as a group. The joint management committee has the authority to make decisions on matters including: o reviewing and approving operational and budgetary plans; o determining the commercial viability of each petroleum discovery; o reviewing and adopting the overall development plan; and o approving significant procurements and expenditures, and insurance coverage. Daily operations of a property subject to a production sharing contract are carried out by the designated operator. The operator is typically responsible for determining and executing operational and budgetary plans and all routine operational matters. Upon discovery of petroleum reserves, the operator is required to submit a detailed overall development plan to the joint management committee. After the foreign partner has fully recovered its exploration and development costs under production sharing contracts in which the foreign partner is the operator, we have the exclusive right to take over the operation of the particular oil or gas field. With the consent of the foreign partner, we may also take over the operation before the foreign partner has fully recovered its exploration and development costs. Ownership of Data and Assets All data, records, samples, vouchers and other original information obtained by foreign partners in the process of exploring, developing and producing offshore petroleum become the property of CNOOC as a state-owned national oil company under PRC law. Through CNOOC, we have unlimited and unrestricted access to the data. Our foreign partners and we have joint ownership in all of the assets purchased, installed or constructed under the production sharing contract until either: o the foreign partners have fully recovered their development costs, or o upon the expiration of the production sharing contract. After that, as a state-owned national oil company under PRC law, CNOOC will assume ownership of all of the assets under the production sharing contracts; our foreign partners and we retain the exclusive right to use the assets during the production period. Abandonment Costs Any party to our production sharing contracts must give prior written notice to the other party or parties if it plans to abandon production of the oil or gas field within the contracted area. If the other party or parties agree to abandon production from the oil or gas field, all parties pay abandonment costs in proportion to their respective percentage of participating interests in the field. If we decide not to abandon production upon notice from a foreign partner, all of such foreign partner's rights and obligations under the production sharing contract in respect of the oil or gas field, including the responsibilities for payment of abandonment costs, terminate automatically. We bear the abandonment costs if we decide to abandon production after an initial decision to proceed with production. In 2005, we accrued for dismantlement costs of approximately Rmb 100 million for oil and gas fields governed by production sharing contracts. Production Tax 58 The PRC production tax rate on the oil and natural gas produced under production sharing contracts is currently 5%. Overseas In addition to our production sharing arrangements in the PRC, we have made production sharing arrangements in several foreign countries and regions, including Indonesia, Australia, Morocco, Nigeria and Myanmar etc. We have interests in production sharing contracts and a technical assistance contract in Indonesia. Indonesian oil and gas activities are currently supervised and controlled by BP MIGAS, the executive agency for upstream oil and gas activities in Indonesia. Under current Indonesian law, BP MIGAS is the sole entity authorized to manage Indonesia's oil and gas resources on behalf of the Indonesian government and to enter into agreements with foreign and domestic companies, functions previously conducted by Pertamina. BP MIGAS enters into production sharing arrangements with private energy companies. The arrangements allow such private companies to explore and develop oil and gas in specified areas in exchange for a percentage interest in the production from such areas. These production sharing arrangements are mainly governed by production sharing contracts, as well as by technical assistance contracts, each of which is described further below. Upon entering into a production sharing arrangement, the operator commits to spending a specified sum of capital to implement an agreed work program. Production sharing arrangements in Indonesia are based on the following principles: o contractors are responsible for all investments (exploration, development and production); o a contractor's investment and production costs are recovered from production; o the profit split between the Indonesian government and contractors is based on production after the cost recovery, domestic market oil, etc; o ownership of tangible assets remains with the Indonesian government; and o overall control lies with BP MIGAS on behalf of the Indonesian government. An original production sharing contract is awarded to explore for and to establish commercial hydrocarbon reserves in a specified area prior to commercial production. The contract is generally awarded for a number of years depending on the contract terms, subject to discovery of commercial quantities of oil and gas within a certain period. The term of the exploration period can generally be extended by agreement between the contractor and BP MIGAS. The contractor is generally required to relinquish specified percentages of the contract area by specified dates unless such designated areas correspond to the surface area of any field in which oil and gas has been discovered. BP MIGAS is typically responsible for managing all production sharing contract operations, assuming and discharging the contractor from all taxes (other than Indonesian corporate taxes, taxes on interest, dividends and royalties and others as set forth in the production sharing contract), obtaining approvals and permits needed by the project and approving the contractor's work program and budget. The responsibilities of a contractor under a production sharing contract generally include advancing necessary funds, furnishing technical aid and preparing and executing the work program and budget. In return, the contractor may freely lift, dispose of and export its share of crude oil and retain the proceeds obtained from its share. The contractor generally has the right to recover all finding and developing costs, as well as operating costs, in each production sharing contract against available revenues generated after deduction of first tranche production of oil and gas, or FTP. Under FTP terms, the parties are entitled to take and receive an annually agreed percentage of production from each production zone or formation each year, 59 prior to any deduction for recovery of operating costs, investment credits and handling of production. FTP for each year is generally shared between the Indonesian government and the contractor in accordance with the standard sharing splits. The balance is available for cost recovery. Post-cost recovery, the Indonesian government is entitled to a specified profit share of crude oil production and of natural gas production. Under each production sharing arrangement, the contractor is obligated to pay Indonesian corporate taxes on its specified profit share at the Indonesian corporate tax rate in effect at the time the agreement is executed. Production sharing contracts in Indonesia have long included a provision known as the domestic market obligation, or DMO, under which a contractor must sell a specified percentage of its crude oil to the local market at a reduced price. After the first five years of a field's production, the contractor is required to supply, the lesser of (i) 25% of the contractor's before-tax share of total crude oil production or (ii) the contractor's share of profit oil. This reduced price varies from contract to contract and is calculated at the point of export. The new Indonesian Oil and Gas Law, which came into force on November 23, 2001, stipulates a gas DMO, under which the contractor must sell up to 25% of its gas entitlement to the domestic market, although it is not clear at what price this gas must be sold. Production sharing contract parties have stated that they would prefer that this price be determined on the open market, and that it be recognized that if there are pre-existing gas sale agreements, or if the project produces LNG for export, the obligation to sell gas into the local market may not be feasible. Technical assistance contracts are awarded when a field has prior or existing production. The oil or gas production is divided into non-shareable and shareable portions. The non-shareable portion represents the expected production from the field at the time the technical assistance contract is signed and is retained by Pertamina. The shareable portion represents the additional production resulting from the operator's investment in the field and is split in the same way as for an original production sharing contract as described above. We also have interests in production sharing contracts in various countries, including Morocco, Nigeria and Myanmar. On May 3, 2004, we, through our wholly owned subsidiary CNOOC Morocco Limited, acquired from Vanco Energy Corporation an 11.25% interest in a petroleum agreement for Ras Tafelney offshore Morocco. In 2004 and 2005, we, Golden Aaron Pte. Ltd. and China Global Construction Limited formed a joint venture in Myanmar and had entered into six production sharing contracts as of June 8, 2005. In January 2006, we acquired a 35% working interest in the contract for OPL 229 in Nigeria. In April 2006, we acquired a 45% interest in offshore Nigerian oil mining license "OML 130". On February 17, 2006, we signed a production sharing contract for block S in Equatorial Guinea. On April 28, 2006, through our wholly-owned subsidiary CNOOC Africa Limited, we signed production sharing contracts for six blocks in Kenya. We will act as the operator under these production sharing contracts. Geophysical Survey Agreements Historically, we conducted our exploration operations through geophysical survey agreements with leading international oil and gas companies through production sharing contracts. For the year ended December 31, 2005, we did not enter into any geophysical survey agreements with third parties, but may enter such agreements in the future. Geophysical survey agreements are designed for foreign petroleum companies to conduct certain geophysical exploration before they decide whether to enter into production sharing contract negotiations with CNOOC. Geophysical survey agreements usually have a term of less than two years. International oil and gas companies must complete all of the work confirmed by both parties in the agreements and bear all the costs and expenses. If a foreign partner decides to enter into a production sharing contract with CNOOC, the costs and expenses that the foreign partner incurs in conducting geophysical survey may be recovered by the foreign partner in the production period subject to our confirmation. CNOOC 60 has the sole ownership of all data and information obtained by the foreign partner during the geophysical survey, and, through CNOOC, we have access to all such data. Under PRC law, the negotiation of a geophysical survey agreement is a function that only a state-owned national company, such as CNOOC, can perform. As part of its reorganization in 1999, CNOOC transferred to us all its commercial rights under a geophysical survey agreement, which has since been completed. In the future, CNOOC has agreed to assign to us all of its commercial rights under any geophysical survey agreements it enters into with international oil and gas companies. Operating Hazards and Uninsured Risks Our operations are subject to hazards and risks inherent in the drilling, production and transportation of crude oil and natural gas, including pipeline ruptures and spills, fires, explosions, encountering formations with abnormal pressures, blowouts, cratering and natural disasters, any of which can result in loss of hydrocarbons, environmental pollution and other damage to our properties and the properties of operators under production sharing contracts. In addition, certain of our crude oil and natural gas operations are located in areas that are subject to tropical weather disturbances, some of which can be severe enough to cause substantial damage to facilities and interrupt production. As protection against operating hazards, we maintain insurance coverage against some, but not all, potential losses, including the loss of wells, blowouts, pipeline leakage or other damage, certain costs of pollution control and physical damages on certain assets. Our insurance coverage includes oil and gas field properties and construction insurance, marine hull insurance, protection and indemnity insurance, drilling equipment insurance, marine cargo insurance and third party and comprehensive general liability insurance. We also carry business interruption insurance for Pinghu Field. In Indonesia, the operators of the production sharing contracts in which we participate are required by local law to purchase insurance policies customarily taken out by international petroleum companies. As of December 31, 2005, we paid an annual insurance premium of approximately Rmb 163.1 million to maintain our insurance coverage. We believe that our level of insurance is adequate and customary for the PRC petroleum industry and international practices. However, we may not have sufficient coverage for some of the risks we face, either because insurance is not available or because of high premium costs. See "Item 3--Key Information--Risk Factors--Risks relating to our business--Exploration, development and production risks and natural disasters affect our operations and could result in losses that are not covered by insurance." For the year ended December 31, 2005, we did not have any uninsured losses. Research and Development Historically, we used research and development services provided by CNOOC's affiliates, including CNOOC Research Center, as well as other international research entities. In July 2003, we established our own research center, CNOOC (China) Limited Research Center, to undertake most of our research and development activities. During the years ended December 31, 2003, 2004 and 2005, our research and development costs were approximately Rmb 165.8 million, Rmb 268.5 million and Rmb 401.6 million, respectively. Our research efforts have focused on: o enhancing oil recovery in offshore China heavy oil fields; o engineering and developing deepwater fields; o engineering and developing marginal fields; and o developing new offshore exploration technology and new exploration areas. We are also studying various ways of utilizing our existing reserves including: 61 o building more accurate reservoir models; o re-processing existing seismic and log data to locate potential areas near existing fields to be integrated into existing production facilities; and o researching ways to reduce development risks for marginal fields and to group fields into joint developments to share common facilities. For further information regarding our agreement with CNOOC Research Center, see "Item 7--Major Shareholders and Related Party Transactions--Related Party Transactions--Categories of Connected Transactions--Research and development services." Regulatory Framework Government Control The PRC government owns all of China's petroleum resources and exercises regulatory control over petroleum exploration and production activities in China. We are required to obtain various governmental approvals, including those from the Ministry of Land and Resources, the State Administration for Environmental Protection, the National Development and Reform Commission and the Ministry of Commerce before we are permitted to conduct production activities. Our sales are coordinated by the National Development and Reform Commission. For joint exploration and production with foreign enterprises, we are required to obtain various governmental approvals, through CNOOC, including those from: o the Ministry of Land and Resources, for a permit for exploration blocks, an approval of a geological reserve report submitted through CNOOC; o the Ministry of Land and Resources or the National Development and Reform Commission to designate such blocks as an area for foreign cooperation; o the Ministry of Commerce for the production sharing contracts between CNOOC and the foreign enterprises; o the State Administration for Environmental Protection for an environmental impact report submitted through CNOOC; o the National Development and Reform Commission for an overall development plan submitted through CNOOC; and o the Ministry of Land and Resources, for an extraction permit. Since the conclusion of the meeting of the National People's Congress in March 2003, the PRC government has undergone substantial reform. It is believed that market-oriented reforms will continue. Special Policies Applicable to the Offshore Petroleum Industry in China Since the early 1980s, the PRC government has adopted policies and measures to encourage the development of the offshore petroleum industry. These policies and measures, which were applicable to CNOOC's operations prior to the reorganization, became applicable to our operations in accordance with an undertaking agreement between us and CNOOC. As approved by the relevant PRC government authorities, including the Ministry of Land and Resources and the Ministry of Commerce, these policies and measures have provided us with the following benefits: 62 o the exclusive right to explore for, develop and produce petroleum offshore China in cooperation with international oil and gas companies and to sell this petroleum in China; o the flexibility to set our prices in accordance with international market prices and determine where to sell our crude oil, with only minimal supervision from the PRC government; o a favorable 5% production tax on the crude oil and natural gas we produce both independently and under production sharing contracts, rather than the 17% rate generally applicable to the independent production of domestic petroleum companies in China; and o production from one of our major gas fields, Yacheng 13-1, is exempt from the PRC royalties under an approval by the State Tax Bureau in May 1989 and the 5% production tax applicable to the oil and gas produced under other production sharing contracts in accordance with an approval by the Ministry of Finance in August 1985. Our natural gas revenues from Yacheng 13-1 for each of the five years ended December 31, 2001, 2002, 2003, 2004 and 2005 represented approximately 7.3%, 5.6%, 3.6%, 3.2% and 2.3%, respectively, of our total oil and natural gas sales in those years. Although we historically have benefited from the foregoing special policies, we cannot assure that such policies will continue in the future. We are also regulated by the PRC government in various other aspects of our business and operations, including required government approvals for new independent development and production projects and new production sharing contracts. For a further discussion of ways in which we are regulated by the PRC government, see "--Government Control." Policies Applicable to International Oil and Gas Companies Operating Offshore China The PRC government encourages foreign participation in offshore petroleum exploration and production through exclusive cooperation with CNOOC. In 1982, the State Council promulgated the Regulation of the People's Republic of China on Exploitation of Offshore Petroleum Resources in Cooperation with Foreign Enterprises, which grants to CNOOC the exclusive right to enter into joint cooperation arrangements with foreign enterprises for offshore petroleum exploration and production. From 1982 to 2000, CNOOC successfully completed several rounds of bidding for offshore petroleum exploration and production projects, and many international oil and gas companies have been involved and awarded exploration blocks for joint exploration, development and production with CNOOC. In October 2001, the State Council amended the regulation referred to above as a part of the comprehensive review of all business laws and regulations by the Chinese government to ensure their compliance with its WTO commitments. The amendment revised such terms in the law governing offshore exploration as restrictive provisions on technology transfers and domestic components requirements in procurement. The removal of these restrictions will provide a level playing field for all oilfield service contractors, domestic or international. These amendments are expected to benefit CNOOC's businesses as well as our exploration and production business and further increase production sharing contract activities offshore China. CNOOC will continue to enjoy the exclusive right to conduct production sharing contract activities with foreign contractors and is entitled to all rights and privileges under the previous regulation. The regulation also states that CNOOC, as a state-owned enterprise, is to be in charge of all efforts to exploit petroleum resources with contractors in Chinese waters. Currently, international oil and gas companies can only undertake offshore petroleum exploration and production activities in China after they have entered into a production sharing contract with CNOOC. In March 2006, the State Council issued the Decision to Impose a Levy on Special Oil Income and the Ministry of Finance promulgated the Management Rules on the Administration of Special Oil Income Levy, effective March 26, 2006. According to the rules, the Ministry of Finance will impose a special oil income levy on any income derived from the sales by an oil exploration and production company of locally produced crude oil at a price which exceeds US$40 per barrel. The special oil income levy will be collected on a quarterly basis. As the international oil prices, exchange rate of Renminbi and our crude oil production fluctuate, the full impact on us as a result of the implementation of the Special oil income levy cannot be ascertained at this time. 63 Environmental Regulation Our operations are required to comply with various applicable environmental laws and regulations, including PRC laws and regulations administered by the central and local government environmental protection bureaus for our operations in China. We are also subject to the environmental rules introduced by governments in whose jurisdictions our onshore logistical support facilities are located. The State Administration for Environmental Protection sets national environmental protection standards and local environmental protection bureaus may set stricter local standards. The relevant environment protection bureau must approve or review each stage of a project. We must file an environmental impact statement or, in some cases, an environmental impact assessment outline before an approval can be issued. The filing must demonstrate that the project conforms to applicable environmental standards. The relevant environmental protection bureau generally issues approvals and permits for projects using modern pollution control measurement technology. The PRC national and local environmental laws and regulations impose fees for the discharge of waste substances above prescribed levels, require the payment of fines for serious violations and provide that the PRC national and local governments may at their own discretion close or suspend any facility which fails to comply with orders requiring it to cease or cure operations causing environmental damage. For the year ended December 31, 2005, we did not experience any major incident of oil spillage. The PRC environmental laws require offshore petroleum developers to pay abandonment costs. Our financial statements include provisions for costs associated with the dismantlement of oil and gas fields during the years ended December 31, 2003, 2004 and 2005 of approximately Rmb 167.3 million, Rmb 201.6 million and Rmb 252.9 million, respectively. Environmental protection and prevention costs and expenses in connection with the operation of offshore petroleum exploitation are covered under each individual production sharing contract. Environmental protection and prevention costs and expenses represented on average approximately 4% of our annual operating costs relating to projects constructed offshore China during the three years ended December 31, 2005. Each platform has its own environmental protection and safety staff responsible for monitoring and operating the environmental protection equipment. However, no assurance can be given that the PRC government will not impose new or stricter regulations which would require additional environmental protection expenditures. We are not currently involved in any environmental claims and believe that our environmental protection systems and facilities are adequate for us to comply with applicable national and local environmental protection regulations. Legal Proceedings We are not a defendant in any material litigation, claim or arbitration, and know of no pending or threatened proceeding which would have a material adverse effect on our financial condition. Patents and Trademarks We own or have licenses to use two trademarks which are of value in the conduct of our business. CNOOC is the owner of the "CNOOC" trademark. Under two non-exclusive license agreements between CNOOC and us, we have obtained the right to use this trademark for a nominal consideration. Real Properties Our corporate headquarters is located in Hong Kong. We also lease several other properties from CNOOC in China and Singapore. The rental payments under these lease agreements are determined with 64 reference to market rates. For further details regarding the terms of these leases, see "Item 7--Major Shareholders and Related Party Transactions--Related Party Transactions--Categories of Connected Transactions--Lease agreement in respect of the Nanshan Terminal," and "--Lease and property management services." We own the following main property interests in the PRC: o land, various buildings and structures at Xingcheng JZ 20-2 Natural Gas Separating Plant, Dongyao Village, Shuangsu Township, Xingcheng City, Liaoning Province; o land, various buildings and structures located at Boxi Processing Plant, South of Jintang Subway, Tanggu District, Tianjin City; o land, various buildings and structures at Weizhou Terminal Processing Plant, Weizhou Island, Weizhou Town, Beihai City, Guangxi Zhuang Autonomous Region; o a parcel of land at Suizhong 36-1 Base, Xiaolihuang Village, Gaoling Town, Suizhong County, Liaoning Province; o land, various buildings and structures located at Bonan Processing Plant, Jimu Island, Longgang Development Zone, Longkou City, Shandong Province; o land, various buildings and structures located at Dongfang 1-1 Processing Plant, Shugang Road, Dongfang City, Hainan Province; o 50% interest in land, various buildings and structures located at Panyu-Huizhou Gas Processing Plant, Huandao North Road, Hengqin Town, Zhuhai City, Guangdong Province; and o land, various buildings and structures located at Chunxiao Gas Processing Plant, Chunxiao Road, Chunxiao Town, Beilun District, Ningbo City, Zhejiang Province. Employees and Employee Benefits During the years ended December 31, 2003, 2004 and 2005, we employed 2,447 persons, 2,524 persons and 2,696 persons, respectively. Of the 2,696 employees we employed as of December 31, 2005, approximately 72.4% were involved in petroleum exploration, development and production activities, approximately 7.1% were involved in accounts and finance work and the remainder were senior management, coordinators of production sharing contracts and safety and environmental supervisors. Workers for the operation of the oil and gas fields, maintenance personnel and ancillary service workers are hired on a contract basis. We have a trade union that: o protects employees' rights; o organizes educational programs; o assists in the fulfillment of economic objectives; o encourages employee participation in management decisions; and o assists in mediating disputes between us and individual employees. We have not been subjected to any strikes or other labor disturbances and believe that relations with our employees are good. 65 The total remuneration of employees includes salary, bonuses and allowances. Bonus for any given period is based primarily on individual and our performance. Employees also receive subsidized housing, health benefits and other miscellaneous subsidies. We have implemented an occupational health and safety program similar to that employed by other international oil and gas companies. Under this program, we closely monitor and record health and safety incidents and promptly report them to government agencies and organizations. On March 15, 2000, we finalized and implemented our occupational health and safety program. We believe this program is broadly in line with the United States government's Occupational Safety & Health Administration guidelines. All full-time employees in the PRC are covered by a government-regulated pension. The PRC government is responsible for the pension of these retired employees. We are required to contribute monthly approximately 9% to 22% of our employees' salaries, with each employee contributing 4% to 8% of his or her salary for retirement. The contributions vary from region to region. Our Indonesian subsidiaries employ approximately 900 employees, including approximately 50 expatriates. We provide benefits to expatriates that we believe to be in line with customary international practices. Our local staff in Indonesia enjoy welfare benefits mandated by Indonesian labor laws. For further details regarding retirement benefits, see note 31 to our consolidated financial statements attached to this annual report. Health, Safety and Environmental Policy We are committed to the promotion of the concept and culture of health, safety and environmental ("HSE") protection among all the staff. The oil and gas field development projects that were started during the year all underwent simultaneous reviews on HSE protection in accordance with the laws of the PRC. In 2005, nearly all the staff from the management to the operational level participated in our HSE training sessions. In addition, the scope of our HSE training has been extended to the employees of contractors. More than 10,000 person-time from our contractors participated in our training sessions in 2005. In 2005, we also placed considerable emphasis on safety in helicopter, diving and vehicle operations. Professional auditors were hired to conduct annual safety audit and safety checks on 11 leased helicopters. In 2006, we plan to carry out special audits on diving operations. We introduced the system of occupation health profiles to all branches in order to strengthen the health management of offshore operating staff in addition to requiring them to submit health certificates. The submitted health data is to be analyzed so as to offer the staff proactive and constructive advices on health improvement. As an International Association of Oil and Gas Producer (OGP) member, we assisted OGP in organizing the "Workshop on Safety Management of Offshore Accidents" in 2005. In 2005, we organized a large-scale offshore emergency drill. There were over 300 participants, including our offshore service contractors and transportation service contractors. We continued to work with other entities to set up Oil Spill Response Base in Tangguh, Longkou, Weizhou and Zhuhai. We believe such initiatives strengthened our capability in handling offshore oil spill emergencies. In 2005, we made sustained progress in respect of HSE management. During the year, we were neither involved in any material injury liability case, spillage or pollution incidents, nor subject to any safety-related liability claims for losses of over US$120,000. Our OSHA Statistics results continued to be above average when compared with international peers. We seek to align our operations with international standards and have been applying for the ISO14000 environmental management qualification for our oilfields. By the end of 2005, our 66 Qinhuangdao 32-6 oilfield and Wenchang oilfields were certified under the ISO14000 environmental management system. We are a member of the "National Offshore Oil Spillage Response Plan" organized by the State Oceanic Administration. In 2005, we continued to conduct researches and participated in discussions on issues relating to resources sharing and risk assessment in the event of oil spillage offshore China. We also continued to cooperate with the Bohai Bay Oil Spillage Awareness Center and facilitated the establishment of the oil spillage response organizations in the South China Sea. In accordance with changes to the statistical requirements of the U.S. Occupational Safety and Health Administration, or OSHA, we revised our internal documentation procedures to keep abreast with OSHA's standard, which uses OGP reporting methods to record the differences and standards of particular incidents. We have also adopted new OSHA and incident reporting forms in order to better meet the requirements of international associations such as OGP and API. We deliver working hour statistics and incident reports to investors and API on a quarterly basis. Human Resources Development As an oil and gas exploration and production company operating in highly competitive markets, we depend in large part on our employees for effective and efficient operations. We devote significant resources to train our technical employees. During 2005, we held 818 training workshops, which were attended by 12,215 participants. To ensure smooth implementation of our overseas strategy, we have established an international human resources system to attract and retain talents in the international market. During the year, we completed the "Compensation Administration and Adjustment Plan". We also introduced various incentive schemes, including the "Project Team Incentive Scheme" and the "New discovery Incentive Scheme". With respect to overseas staff, we continued to improve our remuneration policy to make it competitive in the international market. We also started to build up an international recruitment database to support our overseas business expansion. We have adopted four stock option schemes for our senior management since February 4, 2001, and granted options under three of the schemes. ITEM 4A. UNRESOLVED STAFF COMMENTS None. ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS A. OPERATING RESULTS You should read the following discussion and analysis in conjunction with our consolidated financial statements, selected historical consolidated financial data and operating and reserves data, in each case together with the accompanying notes, contained in this annual report. Our consolidated financial statements have been prepared in accordance with Hong Kong GAAP, which differ in certain material respects from U.S. GAAP. Note 38 to our consolidated financial statements attached to this annual report provides an explanation of our reconciliation to U.S. GAAP of net income and shareholders' equity. Certain statements set forth below constitute "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995. See "Forward-Looking Statements." Overview We are an oil and gas company engaged in the exploration, development and production of crude oil and natural gas primarily offshore China. We are the dominant producer of crude oil and natural gas offshore China and the only company permitted to conduct exploration and production activities with international oil and gas companies offshore China. As of December 31, 2005, we had estimated net proved reserves of 2,362.6 million BOE, comprised of 1,457.4 million barrels of crude oil and condensate 67 and 5,430.9 billion cubic feet of natural gas. In 2005, our net production averaged 356,868 barrels per day of crude oil, condensate and natural gas liquids and 389.6 million cubic feet per day of natural gas, which together totaled 424,108 BOE per day. Our revenues and profitability are largely determined by our production volume and the prices we realize for our crude oil and natural gas, as well as the costs of our exploration and development activities. Although crude oil prices depend on various market factors and have been volatile historically, our production volume has increased steadily over the past few years. The following table sets forth our net production of crude oil, condensate and natural gas liquids and net income for the periods indicated. Year ended December 31, ----------------------------------------------------------- 2001 2002 2003 2004 2005 ------- ------- ------- ------- ------- Net production of crude oil, condensate and natural gas liquids (BOE/day) ........... 228,874 298,625 306,464 319,436 356,868 Net production of natural gas (mmcf/day) .................. 195.0 272.6 291.0 364.1 389.6 Net income (Rmb in millions) (Restated) .................. 7,957.6 9,207.0 11,497.0 16,139.0 25,323.1 We sold 46.9% of our crude oil production in 2005 to customers affiliated with Sinopec or PetroChina in the PRC domestic market. We sold 38.4% of our natural gas production offshore China in 2005 to Castle Peak Power Company Limited in Hong Kong under a long-term take-or-pay contract. For a further description of these factors and certain other factors affecting our financial performance, see "Item 3--Key Information--Risk Factors." Relationship with CNOOC Prior to the October 1999 reorganization of CNOOC, we did not exist as a separate legal entity and our business and operations were conducted by CNOOC and its various affiliates. In connection with the reorganization, CNOOC's oil and gas exploration, development, production and sales business and operations conducted both inside and outside China were transferred to us. See "Item 4--Information on the Company--History and Development--Corporate Structure," "Item 7--Major Shareholders and Related Party Transactions" and note 27 to our consolidated financial statements attached to this annual report. Before the reorganization, certain PRC affiliates of CNOOC provided various materials, utilities and ancillary services for CNOOC's exploration and production activities. In connection with the reorganization, we entered into various agreements under which we continued to use various services and properties provided by these CNOOC affiliates. These agreements include: (i) a materials, utilities and ancillary services supply agreement; (ii) technical service agreements; (iii) agreements for the sale of crude oil, condensate oil and liquefied petroleum gas; (iv) various lease agreements with other affiliates of CNOOC for office and residential premises used by us; and (v) a research and development services agreement with China Offshore Oil Research Center for the provision of general geophysical exploration services, comprehensive exploration research services, information technology services and seismic study. We have renewed these agreements on substantially the same terms. In 2002, CNOOC consolidated most of its oilfield services operations and established China Oilfield Services Limited. This CNOOC affiliate now provides most of the technical services to us. For a description of the services provided under these agreements, see "Item 7--Major Shareholders and Related Party Transactions." Acquisitions and Overseas Activities On January 1, 2003, we acquired BP Muturi Limited, which owned a 44.0% interest in the Muturi production sharing contract offshore Indonesia, and BP Wiriagar Limited's 42.4% interest in the Wiriagar 68 production sharing contract offshore Indonesia for a total consideration of approximately US$275 million. The Muturi production sharing contract and Wiriagar production sharing contract, together with the Berau production sharing contract, make up the Tangguh LNG project. Our interests in these production sharing contracts represented approximately 12.5% of the total reserves and upstream production of the Tangguh LNG project. On May 12, 2004, we completed our acquisition of an additional 20.767% interest in the Muturi production sharing contract from the BG Group. As a result, our interests in these production sharing contracts now represent 16.96% of the total reserves and upstream production of the Tangguh LNG project. The remaining interests are held by BP Berau, BP Muturi, BP Wiriagar, MI Berau, Nippon, BG, KG Berau, KG Wiriagar and Indonesia Natural Gas Resources Muturi. The Tangguh LNG project is a greenfield project located offshore Indonesia and represents one of the largest natural gas projects in Asia. In connection with our acquisition of interests in the Tangguh LNG project, the partners in the Tangguh LNG project entered into a conditional 25-year supply contract to provide up to 2.6 million tonnes of liquefied natural gas per year to a liquefied natural gas terminal project in Fujian Province, China. Supply of liquefied natural gas under this supply contract is expected to begin in 2008. In May 2003, we signed an agreement with the original North West Shelf project partners to acquire an aggregate interest of 5.3% in the upstream production and reserves of the North West Shelf project for a consideration of US$348 million, plus an upfront tariff payment relating to certain LNG processing facilities amounting to US$180 million. We also agreed to acquire a 25% interest in the China LNG joint venture established by the North West Shelf project partners to supply liquefied natural gas from the North West Shelf project to a liquefied natural gas terminal currently being developed by CNOOC, our controlling shareholder, and various partners in Guangdong Province, China. We completed the acquisition in December 2004. Our share of reserves from this project is expected to be approximately 1.2 trillion cubic feet of natural gas. Our share of natural gas together with associated liquids is expected to be approximately 210 million BOE. The partners of the project signed a 25-year LNG supply agreement in December 2004 to provide liquefied natural gas to the Guangdong liquefied natural gas terminal starting 2006. Woodside Petroleum is the operator for the project. See "Item 4--Information on the Company--Business Overview--Natural Gas Business--Overseas Activity." On October 24, 2003, we entered into an agreement with the joint venture participants of the Gorgon natural gas project in Australia based on a memorandum of understanding previously entered into with them, under which we agreed to acquire certain interest in the upstream production and reserves of the Gorgon natural gas project. The memorandum of understanding expired in March 2005. At the end of 2004, we and Golden Aaron Pte. Ltd. and China Global Construction Limited formed a joint venture in Myanmar and entered into six production sharing contracts as of June 8, 2005. We will act as the operator under these production sharing contracts. In early 2005, through our wholly owned subsidiary CNOOC Belgium BVBA, we acquired a 16.69% interest in MEG Energy Corp., a Canada based oil sand company, at a consideration of 150 million Canadian dollars. On January 8, 2006, we signed an agreement with South Atlantic Petroleum Limited to acquire a 45% working interest in an offshore oil-mining license 130 "OML 130" in Nigeria for a cash consideration of US$2.268 billion. The acquisition was completed in April 2006. We also acquired a 35% working interest in the contract for OPL 229 in Nigeria for a consideration of US$60 million. On February 17, 2006, we signed a production sharing contract for block S in Equatorial Guinea. On April 28, 2006, through our wholly-owned subsidiary CNOOC Africa Limited, we signed production sharing contracts for six blocks with a total area of 115,343 square kilometers in Kenya. Production Sharing Contracts Offshore China We conduct a significant amount of our offshore China oil and gas activities through production sharing contracts with international oil and gas companies. Under these production sharing contracts, our 69 foreign partners are required to bear all exploration costs during the exploration period. The parties to the contracts may recover exploration costs after commercial discoveries are made and production begins. The amount of exploration costs recoverable is derived from a production sharing formula set forth in each contract. Our production sharing contracts provide us with the option to take participating interests in properties covered by the production sharing contracts which we may exercise after the foreign partners have made viable commercial discoveries. The foreign partners retain the remaining participating interests. We and the foreign partners fund our development and operating costs according to our respective participating interests. Based on a formula contained in the applicable contract, we are entitled to allocate specified amounts of the annual gross production of petroleum from those producing fields. See "Item 4--Information on the Company--Business Overview--Production Sharing Contracts--Offshore China--Production Sharing Formula." Before we exercise our option to take a participating interest in a production sharing contract, we do not account for the exploration costs incurred, as these costs were incurred by our foreign partners. After we exercise the option to take a participating interest in a production sharing contract, we account for the oil and gas properties using the "proportional method" under which we recognize our share of development costs, revenues and expenses from such operations based on our participating interest in the production sharing contracts. See note 5 to our consolidated financial statements attached to this annual report. The foreign partners have the right to either take possession of their petroleum for sale in the international market or sell their petroleum to us for resale in the PRC market. See "Item 4--Information on the Company--Business Overview--Production Sharing Contracts--Offshore China." As described above, production of crude oil and natural gas is allocated among us, our foreign partners and the PRC government according to a formula contained in the production sharing contracts. We have excluded the government's share oil from net sales in our historical consolidated financial statements. Since our historical consolidated financial statements already exclude the government's share oil from our net sales figure, we do not expect any future share oil payments to affect our results of operations or operating cash flows differently than the effects reflected in our historical consolidated financial statement. For information regarding the historical amounts of government share oil payable to the government, see note 5 to our consolidated financial statements attached to this annual report. For information regarding treatment of the PRC government's share oil, see "Item 4--Information on the Company--Business Overview--Production Sharing Contracts--Offshore China--Production Sharing Formula." Shanghai Petroleum and Natural Gas Company Limited, which owns the Pinghu field, is our associated company. Our 30% equity interest in this company is accounted for using the equity method, under which our proportionate share of the net income or loss of Shanghai Petroleum and Natural Gas Company Limited is included in our consolidated statements of income as a share of income or loss of the associated company. Our cost structures for production sharing contracts and for independent operations are different. The total expenses per unit of production under production sharing contracts are generally higher due to our foreign partners' use of expatriate staff, who generally command higher wages, as well as administrative and overhead costs that may be allocated by the operators, a higher percentage of capital expenditures and larger proportion of imported equipment. Production from Independent Operations offshore China versus Production from Production Sharing Contracts offshore China Historically we have cooperated with foreign partners under production sharing contracts, which have provided us with the expertise to undertake our independent operations more effectively. The percentage of our net production arising from independent operations offshore China was 52.7%, 49.6% and 50.2%, respectively, for the years ended December 31, 2003, 2004 and 2005, respectively. Although 70 we will continue to focus on independent operations, we plan to continue seeking appropriate opportunities to cooperate with foreign partners under production sharing contracts. Provision for dismantlement Prior to 2002, we estimated future dismantlement costs for our oil and gas properties and accrued the costs over the economic lives of the assets using the unit-of-production method. We estimated future dismantlement costs for oil and gas properties with reference to the estimates provided from either internal and external engineers after taking into consideration the anticipated method of dismantlement required in accordance with then current legislation and industry practice. In 2002, we changed the method of accounting for the provision for dismantlement in compliance with Hong Kong Statement of Standard Accounting Practice or HK SSAP 28 (HKAS 37 replaced HK SSAP 28 in 2005), "Provisions, contingent liabilities and contingent assets." HK SSAP 28 requires the provision to be recorded for a present obligation whether that obligation is legal or constructive. The associated cost is capitalized and the liability is discounted and accretion expense is recognized using the credit adjusted risk-free rate in effect when the liability is initially recognized. The dismantlement costs for the years ended December 31, 2003, 2004 and 2005 were Rmb 167.3 million, Rmb 201.6 million and Rmb 252.9 million, respectively. The accrued liability is reflected in our consolidated balance sheet under "provision for dismantlement." See note 28 to our consolidated financial statements attached to this annual report. Production Imbalance We account for oil overlifts and underlifts using the entitlement method, under which we record overlifts as liabilities and underlifts as assets. An overlift occurs when we sell more than our percentage interest of oil from a property subject to a production sharing contract. An underlift occurs when we sell less than our participating interest of oil from a property under a production sharing contract. During the historical periods presented in our consolidated financial statements attached to this annual report, we had no gas imbalances. We believe that production imbalance has not had a significant effect on our operations, liquidity or capital resources. Allowances for Doubtful Accounts We evaluate our accounts receivable by considering the financial condition of our customers, their past payment history and credit standing and other specific factors, including whether the accounts receivable in question are under dispute. We make provisions for accounts receivable when they are overdue for six months and we are concerned about our ability to collect them. For the year ended December 31, 2003, 2004 and 2005, allowances for doubtful accounts were not material in the context of total operating expenses and did not have a material effect on our results of operations or financial condition. Critical Accounting Policies We prepare our consolidated financial statements in accordance with Hong Kong GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of our assets and liabilities, the disclosure of our contingent assets and liabilities as of the date of our financial statements and the reported amounts of our revenues and expenses during the periods reported. Management makes these estimates and judgments based on historical experience and other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. We believe that the following significant accounting policies may involve a higher degree of judgment in the preparation of our consolidated financial statements. For additional discussion of our significant accounting policies, see note 3 to our consolidated financial statements attached to this annual report. Oil and Gas Properties For oil and gas properties, we have adopted the successful efforts method of accounting. As a result, we capitalize initial acquisition costs of oil and gas properties and recognize impairment of initial 71 acquisition costs based on exploratory experience and management judgment. Upon discovery of commercial reserves, we transfer acquisition costs to proved properties and capitalize the costs of drilling and equipping successful exploratory wells, all development costs, and the borrowing costs arising from borrowings used to finance the development of oil and gas properties before they are substantially ready for production. We treat the costs of unsuccessful exploratory wells and all other related exploration costs as expenses when incurred. We amortize capitalized acquisition costs of proved properties by the unit-of-production method on a property-by-property basis based on the total estimated units of proved reserves. We estimate future dismantlement costs for oil and gas properties with reference to the estimates provided from either internal or external engineers after taking into consideration the anticipated method of dismantlement required in accordance with current legislation and industry practices. The associated cost is capitalized and the liability is discounted and an accretion expense is recognized using the credit-adjusted risk-free interest rate in effect when the liability is initially recognized. Impairment of Assets We make an assessment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, or when there is any indication that an impairment loss previously recognized for an asset in prior years may no longer exist or may have decreased. In any event, we would make an estimate of the asset's recoverable amount, which is calculated as the higher of the asset's value in use or its net selling price. We recognize an impairment loss only if the carrying amount of an asset exceeds its recoverable amount. We charge an impairment loss to the income statement in the period in which it arises unless the asset is carried at a revalued amount. For a revalued asset, we account for the impairment loss in accordance with the relevant accounting policy for such revalued asset. A previously recognized impairment loss is reversed only if there has been a change in our estimates used to determine the recoverable amount of an asset. However, no reversal may put the value of the asset higher than the carrying amount that we would have determined (net of any depreciation/amortization) had no impairment loss been recognized for the asset in prior years. A reversal of an impairment loss is credited to the income statement in the period in which it arises, unless the asset is carried at a revalued amount, when the reversal of the impairment loss is accounted for in accordance with the relevant accounting policy for that revalued asset. Provisions We recognize a provision when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation so long as a reliable estimate can be made of the amount of the obligation. When the effect of discounting is material, the amount recognized for a provision is the present value at the balance sheet date of the future expenditures expected to be required to settle the obligation. The increase in the discounted present value amount arising from the passage of time is included in finance costs in the income statement. We make provisions for dismantlement based on the present value of our future costs expected to be incurred, on a property-by-property basis, in respect of our expected dismantlement and abandonment costs at the end of the related oil exploration and recovery activities. Deferred Tax Deferred tax is provided, using the liability method, on all temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. Recognition of Revenue from Oil and Gas Sales and Marketing We recognize revenue when it is probable that the economic benefits will flow to us and when the revenue can be measured reliably. For oil and gas sales, our revenues represent the invoiced value of sales of oil and gas attributable to our interests, net of royalties and any government share oil that is lifted and sold on behalf of the PRC government. Sales are recognized when the significant risks and rewards 72 of ownership of oil and gas have been transferred to customers. Oil and gas lifted and sold by us above or below our participating interests in any production sharing contract result in overlifts and underlifts. We record these transactions in accordance with the entitlement method under which overlifts are recorded as liabilities and underlifts are recorded as assets at year-end oil prices. Settlement will be in kind when the liftings are equalized or in cash when production ceases. We enter into gas sales contracts with customers which typically contain take-or-pay clauses. These clauses require our customers to take a specified minimum volume of gas each year. If a customer fails to take the minimum volume of gas, the customer must pay for the gas even though it did not take the gas. The customer can offset the deficiency payment against any future purchases in excess of the specified volume. We record any deficiency payment as deferred revenue which is included in other payables until any make-up gas is taken by the customer or the expiry of the contract. Our marketing revenues represent sales of oil purchased from the foreign partners under our production sharing contracts and revenues from the trading of oil through our subsidiary in Singapore. The title, together with the risks and rewards of the ownership of such oil purchased from the foreign partners, are transferred to us from the foreign partners and other unrelated oil and gas companies before we sell such oil to our customers. The cost of the oil sold is included in crude oil and product purchases. Results of Operations Overview The following table summarizes the components of our revenues and net production as percentages of our total revenues and total net production for the periods indicated: Year ended December 31, ------------------------------------------------------------------------------ 2003 2004 2005 ------------------------ ------------------------ ------------------------ (Rmb in millions, except percentages, production data and prices) Revenues: Oil and gas sales: (1) Crude oil ................. 25,792 63.0% 34,081 61.7% 50,361 72.5% Natural gas ............... 2,325 5.7% 2,805 5.1% 3,057 4.4% ---------- ---------- ---------- ---------- ---------- ---------- Total oil and gas sales ... 28,117 68.7% 36,886 66.8% 53,418 76.9% Marketing revenues .......... 12,398 30.3% 18,191 32.9% 15,901 22.9% Other income ................ 435 1.1% 145 0.3% 137 0.2% ---------- ---------- ---------- ---------- ---------- ---------- Total revenues ............ 40,950 100.0% 55,222 100.0% 69,456 100.0% ========== ========== ========== ========== ========== ========== Net production (million BOE): Crude oil ................... 111.9 85.9% 116.9 83.5% 130.3 84.2% Natural gas ................. 18.3 14.1% 23.1 16.5% 24.5 15.8% ---------- ---------- ---------- ---------- ---------- ---------- Total net production ...... 130.2 100.0% 140.0 100.0% 154.8 100.0% ========== ========== ========== ========== ========== ========== Average net realized prices: Crude oil (per bbl)......

With respect to revenues derived from our offshore China operations, oil and gas sales represent gross oil and gas sales less royalties and share oil payable to the PRC government. These amounts are calculated as follows: o gross oil and gas sales consist of our percentage interest in total oil and gas sales, comprised of (i) a 100% interest in our independent oil and gas properties and (ii) our participating interest in the properties covered under our production sharing contracts, less an adjustment for production allocable to foreign partners under our production sharing contracts as reimbursement for exploration expenses attributable to our participating interest; o royalties represent royalties we pay to the PRC government on production with respect to each of our oil and gas fields. The amount of royalties varies from 0% up to 12.5% based on the annual production of the relevant property. We pay royalties on oil and gas we produce independently and under production sharing contracts; o government share oil, which is only paid on oil and gas produced under production sharing contracts, is calculated as described under "--Overview--Production Sharing Contracts Offshore China;" o other income mainly represents project management fees charged to our foreign partners and handling fees charged to end customers--both fees are recognized when the services are rendered; and o we pay production taxes to the PRC government that are equal to 5% of the oil and gas we produce independently and under production sharing contracts. Our oil and gas sales are not reduced by production taxes. Production taxes are included in our expenses under "production taxes." Marketing revenues represent our sales of our foreign partners' oil and gas produced under our production sharing contract and purchased by us from our foreign partners under such contracts as well as from international oil and gas companies through our wholly owned subsidiary in Singapore. Net marketing revenues represent the marketing revenues net of the cost of purchasing oil and gas from foreign partners and from international oil and gas companies. Our foreign partners have the right to 74 either take possession of their oil and gas for sale in the international market or to sell their oil and gas to us for resale in the PRC market. Our share of the oil and gas sales of our associated company is not included in our revenues, but our share of the profit or loss of our associated company is included in our consolidated statements of income under "share of profit of associates." Indonesia The oil and gas sales from our subsidiaries in Indonesia consist of our participating interest in the properties covered under the relevant production sharing contracts, less adjustments for share oil payable under our Indonesian production sharing contracts and for a domestic market obligation under which the contractor must sell a specified percentage of its crude oil to the local Indonesian market at a reduced price. 2005 versus 2004 The discussions under "--2005 versus 2004" are based on the restated amounts, where applicable, as a result of the adoption of new HKFRSs. See note 2.4 to our consolidated financial statements under "Item 18-Financial Statement" in this annual report. Consolidated Net Profit Our consolidated net income after tax was Rmb 25,323.1 million (US$3,137.9 million) in 2005, an increase of Rmb 9,184.0 million (US$1,138.0 million), or 56.9%, from Rmb 16,139.1 million in 2004. Revenue Our oil and gas sales for 2005 were Rmb 53,417.7 million (US$6,619.1 million), an increase of Rmb 16,531.7 million (US$2,048.5 million), or 44.8%, from Rmb 36,886.0 million in 2004. The increase primarily reflects the rise in global crude oil prices and production grants. Our sales volume of crude oil and natural gas in 2005 increased by 11.6% and 6.8%, respectively, as compared to 2004. The average realized price for our crude oil was US$47.31 per barrel in 2005, an increase of US$11.9, or 33.6% from US$35.41 per barrel in 2004. The average realized price of natural gas was US$2.82 per thousand cubic feet in 2005, an increase of US$0.07, or 2.6%, from US$2.75 per thousand cubic feet in 2004. In 2005, our net marketing profit, which were derived from marketing revenue less purchase cost of crude oil and oil products, were Rmb 197.2 million (US$24.4 million), a decrease of Rmb 30.7 million (US$3.8 million), or 13.5%, from Rmb 227.9 million in 2004. Since we are one of the three companies that have the right to sell crude oil in China, upon request by our production sharing contract partners, we may purchase the oil of these partners for sale in China. However, the amount of oil we may purchase and sell in China depends on our foreign partners and, therefore, we cannot control the amount of crude oil that we are able to sell for any specific period. In 2005, marketing revenue from our wholly-owned subsidiary, CNOOC China Limited, was Rmb 9,430.8 million (US$1,168.6 million), representing an increase of Rmb 1,688.2 million (US$209.2 million) from Rmb 7,742.6 million in 2004. The net marketing profit, however, decreased Rmb 71.6 million, or 45.7%, from Rmb 156.6 million in 2004. The decrease was primarily due to the significant reduction in sales margin which was mainly influenced by market prices in the local markets. The net marketing profit from our wholly-owned subsidiary, China Offshore Oil (Singapore) International Pte Ltd., was Rmb 112.2 million (US$13.9 million), an increase of Rmb 40.9 million, or 57.4%, from Rmb 71.3 million in 2004. Our other income, reported on a net basis, was derived from our other income less corresponding costs. In 2005, the total other income was Rmb 59.7 million (US$7.4 million), a decrease of Rmb 39.1 million (US$4.8 million) from Rmb 98.8 million in 2004. The decrease was primarily due to the lower service fees received from our production sharing contract projects. 75 Expenses Operating expenses. Our operating expenses were Rmb 5,934.6 million (US$735.4 million) in 2005, an increase of Rmb 864.3 million (US$107.1 million), or 17.0%, from Rmb 5,070.3 million in 2004. The increase was mainly attributable to the commencement of production of seven new oil and gas fields in China in 2005. Operating expenses in 2005 were Rmb 38.8 (US$4.8) per BOE, an increase of 5.7% from Rmb 36.7 per BOE in 2004. Operating expenses for our offshore China operations in 2005 were Rmb 32.5 (US$4.0) per BOE, representing an increase of 8.7% from 2004. The increase was mainly attributable to the higher service fees, supply vessels, equipment lease, maintenance materials, chemicals and fuel, resulting from the higher international crude oil price. Operating expenses for our offshore Indonesia operations were Rmb 100.2 (US$12.4) per BOE, an increase of 13.0% over 2004. The increase in operating expenses per barrel for our Indonesian oil fields was due to lower net production volume based on their profit sharing models. Based on working interest production, operating expenses for our offshore Indonesia operations in 2005 were Rmb 48.7 (US$6.0) per BOE. Production taxes. Our production taxes for 2005 were Rmb 2,596.5 million (US$321.7 million), an increase of Rmb 870.8 million (US$107.9 million), or 50.5% from Rmb 1,725.7 million in 2004. The increase was primarily due to the increased income from oil and gas sales. Exploration costs. Our exploration costs for 2005 were Rmb 1,293.7 million (US$160.3 million), a slight decrease of Rmb 22.5 million (US$2.8 million), or 1.7%, from Rmb 1,316.2 million in 2004, as a result of an increase in capitalization of investment in exploration activities. Depreciation, depletion and amortization expenses. Our depreciation, depletion and amortization expenses for 2005 were Rmb 5,964.7 million (US$739.1 million), an increase of Rmb 509.6 million (US$63.1 million), or 9.3%, from Rmb 5,455.1 million in 2004. On a unit of production basis, depreciation, depletion and amortization expenses for 2005 were Rmb 39.0 (US$4.8) per BOE, as compared to Rmb 39.5 per BOE in 2004. Dismantlement costs. Our dismantlement costs for 2005 were Rmb 252.9 million (US$31.3 million), an increase of Rmb 51.3 million (US$6.4 million), from Rmb 201.6 million in 2004. The increase was primarily due to the increased dismantling costs resulting from the commencement of production at new oil and gas fields and a revision of the dismantlement liabilities for certain existing oil and gas fields. Our dismantlement costs were Rmb 1.7 (US$0.2) per BOE, a corresponding increase from Rmb 1.5 per BOE in 2004. Impairment losses related to property, plant and equipment. Our impairment losses for 2005 were Rmb 90.2 million (US$11.2 million). The impairment was due to the downward revision of the reserve of BZ34-2/4 and HZ19-3 oil and gas fields. The average impairment costs were Rmb 0.6 (US$0.07) per BOE. Selling and administrative expenses. Our selling and administrative expenses for 2005 were Rmb 1,370.4 million (US$169.8 million), an increase of Rmb 266.1 million (US$33.0 million), or 24.1%, from Rmb 1,104.3 million in 2004. Of which, our selling and administrative expenses of companies in China in 2005 were Rmb 6.3 (US$0.8) per BOE, an increase of 14.5% over 2004. Compared with 2004, the increase was mainly attributable to an increase in management fees related to the increased number of production sharing contract projects under production, and increases in labor costs and general research expenditure in 2005. Finance costs, net of interest income Our net finance costs for 2005 was Rmb 741.2 million (US$91.8 million), an increase of 215.5%, from the net interest expenses of Rmb 235.0 million in 2004. On the one hand, our interest income increased by Rmb 152.4 million from Rmb 206.9 million in 2004 to Rmb 359.3 million in 2005. On the other hand, the finance costs increased significantly mainly due to the interest expenses on our US$1 billion bonds issued in December 2004, the losses on fair value changes of the embedded derivative component of the convertible bonds and the effect of increased amount of provision of dismantlement arising from the passage of time. The increases due to the factors mentioned above were Rmb 164.4 76 million (US$20.4 million), Rmb 373.1 million (US$46.2) and Rmb 79.2 million (US$9.8 million), respectively. Exchange Gain/Loss, net Our net exchange gain for 2005 was Rmb 287.0 million (US$35.6 million), an increase of Rmb 257.7 million (US$31.9 million), from net exchange gains of Rmb 29.3 million in 2004. Compared with 2004, the increased exchange gains mainly came from the Chinese government's efforts on the improvement of rate-forming mechanism and the following appreciation of Renminbi in the second half of the year. Investment Income Our short term investment income for 2005 was Rmb 247.9 million (US$30.7 million), a significant increase of Rmb 175.5 million (US$21.7 million), or 242.4%, from Rmb 72.4 million in 2004. For the purpose of improving performance of current assets portfolio, we increased the investment in financial instruments such as money market funds. Benefiting from the structural changes in the investment portfolio and the influence from the market, we obtained a favorable return in this year. Share of Profits of Associates In 2005, there were gains from our investments in Shanghai Petroleum and Natural Gas Company Limited and CNOOC Finance Corporation Limited. Of them, share of profit from Shanghai Petroleum and Natural Gas Company Limited was Rmb 261.8 million (US$32.4 million), representing a decrease of 12.1% from 2004, which was mainly due to the change in tax rate from favorable rate of 16.5% to normal rate of 33.0% and resulting from the increased income tax payment of 2005. Share of profit from CNOOC Finance Corporation Limited was Rmb 45.3 million (US$5.6 million) during the period, relatively comparable to that from 2004. Non-operating Income/Expenses, Net Our net non-operating income for 2005 was Rmb 28.6 million (US$3.5 million), as compared to non-operating income of Rmb 519.2 million for 2004. In 2004, the net non-operating income represented the tax refund from re-investment in China. Income tax Our income tax for 2005 was Rmb 10,977.8 million (US$1,360.3 million), an increase of Rmb 4,047.0 million (US$501.5 million), or 58.4%, from Rmb 6,930.8 million in 2004. The primary reason for the increase was the increase in profit before tax. The effective tax rate for 2005 was 30.2%, slightly higher than the effective rate of 30.0% in 2004. 2004 versus 2003 The discussions under "--2004 versus 2003" are based on the restated amounts, where applicable, as a result of the adoption of new HKFRSs. See note 2.4 to our consolidated financial statements under "Item 18 - Financial Statements" in this annual report. Consolidated Net Profit Our consolidated net income after tax was Rmb 16,139.1 million in 2004, an increase of Rmb 4,641.4 million, or 40.4%, from Rmb 11,497.7 million in 2003. Revenue 77 Our oil and gas sales for 2004 were Rmb 36,886.0 million, an increase of Rmb 8,769.2 million or 31.2%, from Rmb 28,116.8 million in 2003. The increase primarily reflects the rise in global crude oil prices and our higher production level. Our sales of crude oil and natural gas in 2004 increased by 5% and 26%, respectively, as compared to 2003. The average realized price for our crude oil was US$35.41 per barrel in 2004, an increase of US$7.3, or 26.0% from US$28.11 per barrel in 2003. The average realized price of natural gas was US$2.75 per thousand cubic feet in 2004, a decrease of US$0.12, or 4.2%, from US$2.87 per thousand cubic feet in 2003. The decrease was due to the increased weighting of production of low-priced gas fields. In 2004, our net marketing profit, which were derived from marketing revenue less purchase cost of crude oil and oil products, were Rmb 227.9 million, an increase of Rmb 124.5 million, or 120.3%, from Rmb 103.4 million in 2003. Since we are one of the three companies that have the right to sell crude oil in China, upon request by our production sharing contract partners, we may purchase the oil of these partners for sale in China. However, the amount of oil we may purchase and sell in China depends on our foreign partners and, therefore, we cannot control the amount of crude oil that we are able to sell for any specific period. In 2004, our marketing profit from our wholly owned subsidiary, China Offshore Oil (Singapore) International Pte Ltd., was Rmb 71.3 million, an increase of 36.1% from Rmb 52.4 million in 2003. Our other income, reported on a net basis, was derived from our other income less corresponding costs. In 2004, the total other income was Rmb 98.8 million, an increase of Rmb 14.3 million (US$1.7 million) from Rmb 84.5 million in 2003. Expenses Operating expenses. Our operating expenses were Rmb 5,070.3 million in 2004, an increase of Rmb 557.5 million, or 12.4%, from Rmb 4,512.8 million in 2003. The increase primarily resulted from the increased operating expenses in connection with the commencement of operations in new properties. Operating expenses were Rmb 36.7 per BOE in 2004, an increase of 4.2% from Rmb 35.2 per BOE in 2003. Operating expenses offshore China in 2004 were Rmb 29.9 per BOE, an increase of 10.7% from Rmb 27.0 per BOE in 2003. Operating expenses offshore Indonesia were Rmb 88.7 per BOE, an increase of 15.6% from Rmb 76.7 per BOE in 2003. The increases were primarily due to the high international crude oil prices and an increase in operating expenses per barrel for our Indonesian oilfields due to their lower production volume based on their profit sharing model. Based on working interest production, operating expenses for our offshore Indonesia operations in 2004 were Rmb 42.0 per BOE, which were in line with the operating expenses for our offshore Indonesia operations in the previous year. Production taxes. Our production taxes for 2004 were Rmb 1,725.7 million, an increase of Rmb 487.1 million, or 39.3%, from Rmb 1,238.6 million in 2003. The increase was primarily due to increase in oil and gas sales in 2004. Exploration costs. Our exploration costs for 2004 were Rmb 1,316.2 million, an increase of Rmb 468.1 million, or 55.2%, from Rmb 848.1 million in 2003. The increase was primarily due to a significant increase in exploration activities. In 2004, some successful exploration wells were written off because we did not expect to develop these wells within the next couple years. The write-off amount was Rmb 155.8 million. Depreciation, depletion and amortization expenses. Our depreciation, depletion and amortization expenses for 2004 were Rmb 5,455.1 million, an increase of Rmb 812.3 million, or 17.5%, from Rmb 4,642.8 million in 2003. On a unit of production basis, depreciation, depletion and amortization expenses for 2004 were Rmb 39.5 per BOE, an increase of 9.2% compared to Rmb 36.2 per BOE in 2003. The primary reason for the increase was the higher amortization costs for the oilfields that commenced operations in 2004 and the lower production level of the Indonesian oilfields. Based on our profit sharing model, our production level of our Indonesian oilfields is directly affected by oil price fluctuation. 78 Dismantlement costs. Our dismantlement costs for 2004 were Rmb 201.6 million, an increase of Rmb 34.3 million, or 20.5%, from Rmb 167.3 million in 2003. The increase was primarily due to the increased dismantlement costs resulting from the commencement of production at new oil and gas properties. On a unit production basis, our dismantlement costs were Rmb 1.5 per BOE, an increase of 15.3% compared to Rmb 1.3 per BOE in 2003. Selling and administrative expenses. Our selling and administrative expenses for 2004 were Rmb 1, 104.3 million, a decrease of Rmb 145.9 million, or 11.7%, from Rmb 1,250.3 million in 2003. The primary reason for the decrease was a decrease in labor costs resulting from the direct charge of some labor costs to specific projects and the replacement of some foreign employees that received higher salaries with local employees. On a unit of production basis, selling and administrative expenses were Rmb 8.0 per BOE in 2004, a decrease of 19.1% from Rmb 9.7 per BOE in 2003. Our selling and administrative expenses in China in 2004 were Rmb 5.5 per BOE, a decrease of 17.9% from 2003. Net interest expenses/income Our net interest expense for 2004 was Rmb 235.0 million, an increase of Rmb 63.6 million, or 37.1%, from Rmb 171.4 million in 2003. The increase was primarily due to the interest expenses on our US$500 million bonds issued in 2003. Rmb 94.8 million of the increase in interest expense was attributable to our long term guaranteed notes. Exchange Gain/Loss, net Our net exchange gain for 2004 was Rmb 29.3 million, compared with a net exchange loss of Rmb 6.7 million in 2003. The exchange gain in 2004 was mainly attributable to our foreign currency swaps for our yen-denominated loans. Short Term Investment Income Our short term investment income for 2004 was Rmb 72.4 million, a decrease of Rmb 51.1 million, or 41.4%, from Rmb 123.5 million in 2003. The decrease was primarily due to the structural change to our investment portfolio, where we disposed of some of our investment in corporate bonds and reinvested the proceeds in market funds. Share of Profit of Associates Our share of profit of associates for 2004 was Rmb 344.5 million, an increase of Rmb 124.2 million, or 56.4%, from Rmb 220.3 million in 2003. This item reflected our share of profit generated by Shanghai Petroleum and Natural Gas Company Limited resulting primarily from increases in production and oil prices and our share of profit generated by CNOOC Finance Corporation Limited. Non-operating Income/Expenses, Net Our net non-operating income for 2004 was Rmb 519.2 million, compared to non-operating income of Rmb 315 million for 2003. In 2004, the net non-operating income was mainly due to the tax refund from re-investment in China. Income tax Our income tax for 2004 was Rmb 6,930.8 million, an increase of Rmb 2,303.0 million, or 49.8%, from Rmb 4,627.8 million in 2003. The primary reason for the increase was the increase in profit before tax. In 2003, we received Rmb 252.0 million tax rebate for using domestic equipment. The effective tax rate for 2004 was 30.0%, as compared with the effective rate of 28.7% in 2003. 79 B. LIQUIDITY AND CAPITAL RESOURCES The following table summarizes our cash flows for the periods presented: Year ended December 31, ----------------------------------- 2003 2004 2005 --------- --------- --------- (Rmb in millions) Cash provided by (used for): Operating activities ................ 17,819 22,328 32,154 Investing activities ................ (9,513) (24,607) (29,349) Financing activities ................ (1,745) 1,970 (7,787) --------- --------- --------- Net increase/(decrease) in cash and cash equivalents ...................... 6,561 (309) (4,982) ========= ========= ========= Cash Provided by Operations Net cash generated from operating activities in 2005 amounted to Rmb 32,153.8 million (US$3,984.3 million), representing an increase of Rmb 9,825.9 million (US$1,217.6 million), or 44.0% from Rmb 22,327.9 million in 2004. The increase was primarily due to an increase in profit before tax of Rmb 13,231.0 million (US$1,639.5 million), an increase in depreciation, depletion and amortization expenses of Rmb 509.7 million (US$63.2 million), an increase in finance costs of Rmb 658.7 million (US$81.6 million), an increase in provision for inventory of Rmb 35.8 million (US$4.4 million), an increase in dismantlement costs of Rmb 51.2 million (US$6.3 million), a decrease in share of profits of associates of Rmb 37.4 million (US$4.6 million), an increase in amortization of discount of long term guaranteed notes of Rmb 26.3 million (US$3.3 million), and an increase in impairment losses related to property, plant and equipment of Rmb 90.2 million (US$11.2 million). Increase of cash flow was also partially offset by an increase of income tax paid of Rmb 2,447.2 million (US$303.2 million), an increase in our finance exchange gain and loss of Rmb 257.8 million (US$31.9 million), an increase in investment income received of Rmb 175.5 million (US$21.7 million), a decrease in the loss on disposal and write off of property, plant and equipment of Rmb 14.3 million (US$1.8 million), an increase in interest income of Rmb 152.4 million (US$18.9 million) and a decrease in compensation cost for share based payment of Rmb 17.5 million (US$2.2 million). In another aspect, compared with 2004, the increase in operating cash flow was partially attributable to the increase in changes of working capital, mainly due to the increase in changes of current assets from operating activities excluding cash and bank balances of Rmb 2,103.9 million (US$260.7 million), and a simultaneous increase in changes of current liabilities from operating activities of Rmb 71.0 million (US$8.8 million). Capital Expenditures and Investments Net cash outflow from investing activities in 2005 was Rmb 29,349.2 million (US$3,636.7 million), representing an increase of Rmb 4,742.0 million (US$587.6 million), from Rmb 24,607.2 million in 2004. In line with our use of "successful efforts" method of accounting, total capital expenditures and investments primarily include successful exploration and development expenditures and purchasing costs of oil and gas properties. Total capital expenditures were Rmb 17,469.5 million (US$2,164.7 million) in 2005, representing a decrease of Rmb 1,152.5 million (US$142.8 million), or 6.2%, from Rmb 18,622.0 million in 2004. The capital expenditures in 2005 mainly comprised of Rmb 875.8 million (US$108.5 million) for capitalized exploration activities, Rmb 15,729.7 million (US$1,949.1 million) for development activities, and Rmb 1,017.0 million (US$126.0 million) for acquiring 16.69% equity interest in MEG, netting off a tax refund of Rmb 153.0 million (US$ 19.0 million) for the North West Shelf project in Australia. Our development expenditures in 2005 related principally to the development of PanYu 30-1, Bozhong 25-1/25-1S, PL19-3 phase II and NanPu 35-2 oil and gas fields. 80 In addition, cash outflow was attributable to the increase in time deposits with maturities over three months of Rmb 3,597 million (US$445.7 million), and the net purchase of available-for-sale financial assets of Rmb 8,282.7 million (US$1,026.3 million). Total capital expenditures were Rmb 18,622.0 million in 2004, an increase of Rmb 6,249.5 million, or 50.5%, from Rmb 12,372.5 million in 2003. The capital expenditures in 2004 included Rmb 783.5 million for capitalized exploration activities, Rmb 12,059.4 million for development activities, and Rmb 5,779.1 million for acquiring the Tangguh LNG project, the North West Shelf project and other oil and gas properties. Our development expenditures in 2004 related principally to the development of Bozhong 25-1/25-1S, Luda, Bonan and Caofeidian oil and gas fields. In addition, cash outflow in 2004 was in part attributable to an increase in time deposits with maturities over three months of Rmb 6,280 million, which was partially offset by cash inflow from net disposal of short-term investment of Rmb 294.8 million. For 2006, we have budgeted approximately US$3.08 billion for capital expenditures, approximately US$316.3 million of which is budgeted for general exploration activities offshore China, approximately US$1,860.1 million of which is budgeted for development activities offshore China and approximately US$514.5 million of which is budgeted for our exploration and development activities overseas. The following table sets forth actual or budgeted capital expenditures on an accrual basis for our key operating areas for the periods indicated. Year ended December 31, ------------------------- 2005(1) 2006(2) ---------- ---------- Operating Area: (US$ in millions) Bohai Bay Development ................................... 856.4 1,099.5 Exploration ................................... 84.3 136.5 Western South China Sea Development ................................... 161.3 441.3 Exploration ................................... 76.0 113.4 East China Sea Development ................................... 105.0 30.3 Exploration ................................... 6.3 12.1 East South China Sea Development ................................... 554.1 271.5 Exploration ................................... 52.9 32.9 Other Offshore China Development ................................... -- 17.4 Exploration ................................... 13.4 21.4 Overseas Development ................................... 288.5 373.1 Exploration ................................... 19.6 141.4 ---------- ---------- Total ...................................... 2,217.7 2,690.8 ========== ========== ----------------------- (1) Figures for 2005 represent our actual spending for capital expenditure purposes. (2) Figures for 2006 represent our budgeted capital expenditures. In addition to the budgeted development and exploration expenditures relating to the oil and gas properties described above, we may make additional capital expenditures and investments in these periods consistent with our business strategy. See "Item 4--Information on the Company--Business Overview--Business Strategy." Our ability to maintain and grow our revenues, net income and cash flows depends upon continued capital spending. We adjust our capital expenditure and investment budget on an annual basis. Our capital expenditure plans are subject to a number of risks, contingencies and other factors, some of 81 which are beyond our control. Therefore, our actual future capital expenditures and investments will likely be different from our current planned amounts, and such differences may be significant. See "Item 3--Key Information--Risk Factors--Risks relating to our business--Our future prospects largely depend on our capital expenditure plans, which are subject to various risks." Financing activities The net cash outflow arising from financing activities in 2005 was Rmb 7,786.4 million (US$964.8 million) as compared to a net cash inflow of Rmb 1,970.5 million from financing activities in 2004. There was no issuance of debt financing instruments or bank loan increase in 2005. The net cash outflow in 2005 was primarily due to the distribution of dividends of Rmb 7,772.2 million (US$963.1 million) and the repayment of bank loans of Rmb 18.7 million (US$2.3 million). Some cash inflow was generated by the proceeds from the exercise of share options of Rmb 4.5 million (US$0.6 million) in 2005. We had net cash inflows from financing activities of Rmb 1,970.5 million in 2004, primarily attributable to the convertible bond issuance which generated cash inflow of approximately Rmb 8,154.1 million. The cash inflows were partially offset by our repayment of Rmb 21.1 million in bank loans, dividend distributions of Rmb 6,101.4 million and a cash outflow of Rmb 61.2 million resulting from our share repurchases in 2004. We have debt service obligations consisting of principal and interest payments on our outstanding indebtedness. The following table summarizes the maturities of our long-term debt outstanding as of December 31, 2005. As of the date this annual report is filed, we have not incurred any material long-term debt since December 31, 2005. Debt maturities (principal only) ------------------------------------------------------------------ Original currency -------------------------------------- Total Rmb Total US$ Due by December 31, US$ JPY Rmb equivalents equivalents ------------------------ ---------- ---------- ---------- ---------- ---------- (in millions, except percentages) 2006 ................... 100.0 271.5 -- 825.7 102.3 2007-2009 .............. 1,000.0 271.4 -- 8,088.9 1,002.3 2010-2011 .............. -- -- -- -- -- 2011 and beyond ........ 1,000.0 -- -- 8,070.2 1,000.0 Total ............... 2,100.0 542.9 -- 16,984.8 2,104.6 Percentage of total debt 99.8% 0.2% -- 100.0% 100.0% As of June 6, 2006, we had a total U.S. dollar debt of US$2,100.0 million and a total foreign currency debt of US$2,104.6 million. After we became a separate entity in October 1999, we paid a dividend of Rmb 1,045.4 million in 1999 and declared and paid a final dividend of Rmb 6,426.4 million in 2000. In 2002, 2003 and 2004, we paid dividends totaling Rmb 2,265.1 million, Rmb 5,403.7 million and Rmb 6,101.4 million, respectively. In 2005, we declared and paid dividends totaling Rmb 7,772.2 million (US$963.1 million). The payment and the amount of any dividends in the future will depend on our results of operations, cash flows, financial condition, the payment by our subsidiaries of cash dividends to us, future prospects and other factors which our directors may consider relevant. The amount of dividends we paid historically is not indicative of the dividends that we will pay in the future. We believe our future cash flows from operations, borrowing capacity and funds raised from our debt offerings will be sufficient to fund planned capital expenditures and investments, debt maturities and working capital requirements through at least 2006. Several large financial institutions have expressed an interest in supporting our business development, although we have not entered into any agreements for additional financing with these institutions. However, our ability to obtain adequate financing to satisfy our capital expenditure and debt service requirements may be limited by our financial condition and results of operations and the liquidity of international and domestic financial markets, including the following factors: 82 o Any failure by us to achieve timely rollover, extension or refinancing of our short-term debt may result in our inability to meet our obligations in connection with debt service, accounts payable and/or other liabilities when they become due and payable. o Our primary operating subsidiary is a PRC incorporated company. Therefore, prior to accessing the international capital markets we will be subject to limitations imposed by various PRC government authorities, including the State Administration for Foreign Exchange, depending on the type of international financing raised. We may also need to obtain PRC government support for any project involving significant capital investment in the operations of our PRC subsidiary. o In addition, financing sources often look to similarly situated entities when determining whether, and at what rates, to provide financing. Successful or unsuccessful financing by Hong Kong and PRC entities similarly situated to us could have an impact on our ability to obtain external financing. See "Item 3--Key Information--Risk Factors--Risks relating to our business--Our future prospects largely depend on our capital expenditure plans, which are subject to various risks" and "--We may not be able to obtain external financing that is acceptable to us for business development purposes." Employee Benefits When we became a separate entity as a result of CNOOC's reorganization in October 1999, CNOOC retained all liabilities for retirement benefits for its employees, both former and current, who had not been transferred to us. As compensation for CNOOC's retention of liabilities for retirement benefits payable to approximately 7,000 retired CNOOC employees who were previously engaged in the oil and gas business that was transferred to us in the reorganization, we made a one-time payment to CNOOC of Rmb 1,660.0 million in 2001. All of our full-time employees in the PRC are covered by a government-regulated pension plan and are entitled to an annual pension at their retirement dates. The PRC government is responsible for the pension liabilities to these retired employees under this government pension plan. The actual pension payable to each retiree is subject to a formula based on the status of the individual pension account, general salary and inflation movements. We are required to make annual contributions to the government pension plan at rates ranging from 9% to 22% of our employees' salaries. The related pension costs are expensed as incurred. The expenses attributable to mandatory contributions under the current government pension plan are included in our historical consolidated statements of income under either operating expenses for our production staff or selling and administrative expenses for our administrative staff. We expect that, under the current PRC rules and regulations regarding employee retirement benefits, the future costs of the current government plan will be comparable to our historical costs, subject to customary increases largely in line with salary increases of our employees. We are required to make contributions to a mandatory provident fund at a rate of 5% of the base salaries for full-time employees in Hong Kong. The costs are expensed as incurred. Our Indonesian subsidiaries employ approximately 900 employees, including approximately 50 expatriates. We provide benefits to expatriates that we believe to be in line with customary international practices. Our local staff in Indonesia enjoy welfare benefits mandated by Indonesia labor laws. Holding Company Structure We are a holding company. Our entire petroleum exploration, development, production and sales business in the PRC is owned and conducted by CNOOC China Limited, our wholly foreign-owned enterprise in the PRC. Our entire petroleum exploration, development and production business outside the PRC is owned and conducted by CNOOC International Limited, our wholly-owned subsidiary 83 incorporated in the British Virgin Islands. International sales of crude oil are conducted by China Offshore Oil (Singapore) International Pte. Ltd., our wholly-owned subsidiary incorporated in Singapore. Accordingly, our future cash flows will consist principally of dividends from our subsidiaries. The subsidiaries' ability to pay dividends to us is subject to various restrictions, including legal restrictions in their jurisdictions of incorporation. For example, legal restrictions in the PRC permit payment of dividends only out of net income determined in accordance with PRC accounting standards and regulations. In addition, under PRC law, CNOOC China Limited is required to set aside a portion of its net income each year to fund certain reserve funds. These reserves are not distributable as cash dividends. Inflation/Deflation According to the China Statistical Bureau, China experienced an overall national deflation rate, as represented by the general consumer price index, of 1.2% in 2003, an overall inflation rate of 3.9% in 2004 and an overall inflation rate of 1.8% in 2005. Neither the deflation nor the inflation has had a significant impact on our results of operations in the respective years. U.S. GAAP Reconciliation Our consolidated financial statements are prepared in accordance with Hong Kong GAAP, which differ in certain material respects from U.S. GAAP. These differences relate primarily to the treatment of impairment of long-lived assets and the treatment for convertible bonds. For differences between Hong Kong GAAP and U.S. GAAP that affect our net income or shareholders' equity. Please refer to note 38 to our consolidated financial statements attached to this annual report. Taxation We are subject to income taxes on an entity basis on income arising in or derived from the tax jurisdictions in which we and each of our subsidiaries are domiciled and operate. We are not liable for income taxes in Hong Kong as we currently do not have any assessable income from Hong Kong sources. Pursuant to a notice issued by the State Administration of Taxation in March 2001, we are entitled to all tax benefits conferred by Chinese law on foreign invested enterprises. Our PRC subsidiary, absent exemptions, is subject to enterprise income tax at the rate of 33%. Following the October 1999 reorganization, our PRC subsidiary became a wholly foreign owned enterprise and accordingly was exempted from 3% local surcharges, reducing its enterprise income tax rate to the current rate of 30%. The PRC enterprise income tax is levied based on taxable income including income from operations as well as other components of earnings, as determined in accordance with the generally accepted accounting principles in the PRC, or PRC GAAP. Besides income taxes, our PRC subsidiary also pays certain other taxes, including: o production taxes equal to 5% of independent production and production under production sharing contracts; and o business tax of 5% on other income. Our subsidiary in Singapore, China Offshore Oil (Singapore) International Pte. Ltd., is subject to income tax at the rate of 10% and 20% for its oil trading activities and other income-generating activities, respectively. Our subsidiaries that own interests in oil properties in Indonesia along the Malacca Strait are subject to corporate and branch profit tax of 44%. The nine subsidiaries of Repsol-YPF, S.A. in Indonesia acquired by us during 2002 are all subject to corporate and dividend tax at rates ranging from 43.125% to 51.875%. None of our other subsidiaries were subject to any income taxes in their respective jurisdictions for the years presented. We calculate deferred taxation to account for temporary differences between our tax bases, which is used for income tax reporting and prepared in accordance with applicable tax guidelines, and our accounting bases, which is prepared in accordance with applicable financial reporting requirements. Major temporary differences include accelerated amortization allowances for oil and gas properties, 84 which are offset in part by provision for dismantlement and a provision for impairment of property, plant and equipment and write-off of unsuccessful exploratory drilling. As of December 31, 2003, 2004 and 2005, we had Rmb 5,783.2 million, Rmb 6,688.5 million and Rmb 6,827.9 million (US$846.1 million), respectively, in net deferred tax liabilities. See note 13 to our consolidated financial statements attached to this annual report. Change of Accountants On June 6, 2002, we terminated the engagement of Arthur Andersen & Co as our independent public accountants. Prior to such date, Arthur Andersen had audited our consolidated financial statements, including financial statements as of and for the year ended December 31, 2001 presented in "Item 3--Selected Financial Data." On June 15, 2002, Arthur Andersen was convicted of federal obstruction of justice charges in connection with the U.S. government's investigation of Enron Corporation. On August 31, 2002, Arthur Andersen voluntarily relinquished its licenses to practice public accountancy in all states of the United States and, accordingly, cannot furnish any written consent to the issue of this annual report with the inclusion of its reports in the form and context in which they are included. For a discussion of risks related to Arthur Andersen, see "Item 3--Key Information--Risk Factors--Risks relating to our business--You may not be able to assert claims against Arthur Andersen, our independent public accountants for periods prior to 2002, nor may you be able to assert claims against our current independent public accountants for financial statements previously audited by Arthur Andersen." On June 6, 2002, we appointed Ernst & Young as our independent accountants. Ernst & Young audited our consolidated financial statements for the year period ended December 31, 2003, 2004 and 2005 included in this annual report. Impact of Recently Issued Accounting Standards U.S. GAAP In December 2004, the Financial Accounting standards Board ("FASB"), issued SFAS No. 153, "Exchanges of Non-monetary Assets an amendment of APB Opinion No. 29". This Statement, which addresses the measurement of exchanges of non-monetary assets, is effective prospectively for non-monetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. The adoption of this Statement is not expected to impact our consolidated financial position or results of operations. In December 2004, the FASB issued Statement No. 123 (revised 2004), "Share-Based Payment" (FAS No.123R), which replaces FAS No. 123 and supersedes APB Opinion No. 25, "Accounting for Stock Issued to Employees." FAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values beginning with the first interim period after June 15, 2005, with early adoption encouraged. Under the SEC's rules, FAS No. 123R is effective for us beginning January 1, 2006. The pro forma disclosures previously permitted under FAS No. 123 are no longer an alternative to financial statement recognition. We believe the adoption of the FAS No. 123R will have no material impact on our consolidated financial position or results of operations as we currently account for the stock options under the fair value recognition provision of FAS No. 123. In 2005, the FASB has finalized an amendment to Statement No. 19, "Financial Accounting and Reporting by Oil and Gas Producing Companies" (FAS No. 19) that change the way oil and gas producers account for deferred exploratory drilling costs. The new standard would relax the one-year limitation, so long as oil and gas reserves have been discovered and an enterprise "is making sufficient progress assessing the reserves and the economic and operating viability of the project." We believe the adoption of amendment to FAS No. 19 will have no material impact on our consolidated financial position or results of operations. This amendment is effective for the first reporting period beginning after April 4, 2005. In March 2005, the FASB issued FASB Interpretation Number 47 (FIN No. 47), "Accounting for Conditional Asset Retirement Obligations". The interpretation clarifies the requirement to record 85 abandonment liabilities arising from legal obligations when the asset retirement depends on a conditional future event. FIN No. 47 requires that the uncertainty about the timing or method of settlement of a conditional asset retirement obligation be factored into the measurement of the liability when sufficient information available. FIN No. 47 is effective for fiscal years ending after December 15, 2005 and application of the interpretation did not change our calculation of abandonment obligations. In May 2005, the FASB issued SFAS No.154, iss.Accounting Changes and Error Corrections,i<168>a replacement of APB Opinion No.20, iss.Accounting Changesi<168> and SFAS No.3, iss.Reporting Accounting Changes in Interim Financial Statementsi<168> (" SFAS No.154 "). SFAS No.154 changes the requirements for the accounting for, and reporting of, a change in accounting principle. Previously, voluntary changes in accounting principles were generally required to be recognized by way of a cumulative effect adjustment within net income during the period of the change. SFAS No.154 requires retrospective application to prior periods' financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No.154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the statement does not change the transition provisions of any existing accounting pronouncements. We do not believe adoption of SFAS No.155 will have a material effect on our financial position, cash flows or results of operations. In February 2006, the FASB issued SFAS No.155 "Accounting for Certain Hybrid Financial Instruments, an amendment of FASB Statements No.133 and 140" ("SFAS No.155"). SFAS No.155 clarifies certain issues relating to embedded derivatives and beneficial interests in securitized financial assets, including permitting fair value measurement for any hybrid financial instrument that contains an embedded derivative, eliminating the prohibition on a qualifying special-purpose entity from holding certain derivative instruments, and providing clarification that concentrations of credit risk in the form of subordination are not embedded derivatives. The provisions of SFAS No.155 are effective for all financial instruments acquired or issued after fiscal years beginning after September 15, 2006. We do not believe adoption of SFAS No.154 will have a material effect on our financial position, cash flows or results of operations. Hong Kong GAAP The Hong Kong Institute of Certified Public Accountants has issued a number of new and revised HKFRSs, some of which are not mandatory for the current year financial statements. The following new and revised HKFRSs, although not early adopted by us, will have an impact on our financial statements once applied. Unless otherwise stated, the following HKFRSs are effective for accounting periods beginning on or after January 1, 2006: HKAS 1 Amendment Capital Disclosures HKAS 21 Amendment The effects of Changes in Foreign Exchange Rate - Net Investment in a Foreign Operation HKAS 39 Amendment Cash Flow Hedge Accounting of Forecast Intragroup Transactions HKAS 39 Amendment The Fair Value Option HKFRSs 1 & 6 Amendments First-time Adoption of Hong Kong Financial Reporting Standards and Exploration for and Evaluation of Mineral Resources HKFRS 6 Exploration for and Evaluation of Mineral Resources HKFRS 7 Financial Instruments: Disclosures HK(IFRIC)-Int 4 Determining whether an Arrangement contains a Lease HK(IFRIC)-Int 5 Rights to Interests arising from Decommissioning, Restoration and Environmental Rehabilitation Funds HKAS 1 Amendment shall be applied for accounting periods beginning on or after January 1, 2007. The revised standard will affect the disclosure of qualitative information about our objective, policies and processes for managing capital; quantitative data about what we regard as capital; and compliance with any capital requirements and the consequences of any non-compliance. 86 HKFRS 6 deals with the accounting for exploration for and evaluation of mineral resources, including oil and gas. We do not expect the adoption of HKFRS 6 to have any significant impact on our results of operations and financial position. HKFRS 7 has modified the disclosure requirements of HKAS 32 relating to financial instruments, and will replace HKAS 32. This HKFRS shall be applied for accounting periods beginning on or after January 1, 2007. Except as stated above, we do not expect the adoption of the other pronouncements listed above to have any significant impact on our financial statements in the period of initial application. C. RESEARCH AND DEVELOPMENT, PATENTS AND LICENSES, ETC. See "Item 4--Information on the Company--Business Overview--Research and Development" and "Item 7--Major Shareholders and Related Party Transactions--Related Party Transactions--Categories of Connected Transactions--Research and Development Services." D. TREND INFORMATION Crude oil price is a major driver of our results of operation. We price our crude oil with reference to the international crude oil prices, which have fluctuated considerably over the years. On January 3, 2005 the international benchmark crude oil, West Texas Intermediate, was US$42.13 per barrel. As of June 6, 2006, it was US$72.50 per barrel. In addition, continued political and economic uncertainties in Iraq and threat of terrorism worldwide raise concerns about the security and availability of ample supplies to meet growing demand. It is expected that crude oil price will remain relatively high in 2006. For more information about crude oil prices, see "Item 3--Key Information--Risk Factors--Risks Relating to Our Business--Our business, revenues and profits fluctuate with changes in oil and gas prices," "Item 4--Information on the Company--Business Overview--Sales and Marketing--Sales of Offshore Crude Oil--Pricing," and "Item 5--Operating and Financial Review and Prospects--Operating Results--Results of Operations--2005 versus 2004." In additional to crude oil, natural gas is becoming an increasingly important part of our business. The Chinese government promotes the use of natural gas as a clean and efficient fuel. Demand for natural gas in the PRC is likely to increase significantly. We have expanded and will continue to expand our natural gas business and intend to exploit our natural gas reserves to meet growing demand for natural gas. For more information about our natural gas business, see "Item 3--Key Information--Risk Factors--Risks Relating to Our Business--Any failure to implement our natural gas business strategy may adversely affect our business and financial position," "--The infrastructure and demand for natural gas in the PRC may proceed at a slower pace than our planned increase in production," "Item 4--Information on the Company--Business Overview--Competitive Strengths--Strategic Position in China's Growing Natural Gas Market" and "--Natural Gas Business."

Summary of Significant Differences in Corporate Governance Practices for Purposes of Section 303A.11 of the New York Stock Exchange Listed Company Manual We are incorporated under the laws of Hong Kong. The principal trading market for our shares is the Hong Kong Stock Exchange. In addition, because our ordinary shares are registered with the United States Securities and Exchange Commission and are listed on the New York Stock Exchange (the "NYSE"), we are subject to certain corporate governance requirements. However, many of the corporate governance rules in the NYSE Listed Company Manual (the "NYSE Standards") do not apply to us as a "foreign private issuer" and we are permitted to follow the corporate governance practices in Hong Kong in lieu of most corporate governance standards contained in the NYSE Standards. Section 303A.11 of the NYSE Standards requires NYSE-listed foreign private issuers to describe the significant differences between their corporate governance practices and the corporate governance standards applicable to U.S. 97 domestic companies listed on the NYSE ("U.S. domestic issuers"). We set forth below a brief summary of such significant differences. 1. Board and Committee Independence While NYSE Standards require U.S. domestic issuers to have a majority of independent directors, we are not subject to this requirement. Five of our twelve directors are independent non-executive directors. NYSE Standards require U.S. domestic issuers to schedule an executive session at least once a year to be attended by only independent directors. We are not subject to such requirement and our independent directors attend all board meetings where possible. NYSE Standards require U.S. domestic issuers to disclose a method for interested parties to communicate directly with the presiding director or with non-management directors as a group. We are not subject to such requirement and we have not adopted such a method yet. 2. Audit Committee If an audit committee member simultaneously serves on the audit committees of more than three public companies, and the listed company does not limit the number of audit committees on which its audit committee members serve to three or less, then in each case, the boards of directors of U.S. domestic issuers are required to determine that such simultaneous service would not impair the ability of such member to effectively serve on its audit committee and disclose such determination in its annual proxy statement or annual report. We are not subject to such requirement and we have not addressed this in our audit committee charter. NYSE Standards require audit committees of U.S. domestic issuers to discuss guidelines and policies that govern the process by which risk assessment and risk management are handled and include such responsibilities in their audit committee charters. We are not subject to such requirement and our audit committee charter does not have such provision. Our audit committee charter only provides that our audit committee shall review with our auditors and the Director of Internal Audit the scope, adequacy and effectiveness of our corporate accounting and financial controls, and any related significant findings regarding risks or exposures and consider recommendations for improvement of such controls according to the Hong Kong Stock Exchange Listing Rules. 3. Remuneration Committee NYSE Standards require U.S. domestic issuers to have a compensation committee composed entirely of independent directors. We are not subject to such requirement and have a remuneration committee that consists of three independent non-executive directors and one executive director. NYSE Standards require U.S. domestic issuers to address in their remuneration committee charters matters regarding committee member removal and committee structure and operations (including authority to delegate to subcommittees). We are not subject to such requirement and we have not addressed this in our remuneration committee charter. NYSE Standards require remuneration committees of U.S. domestic issuers to produce a remuneration committee report annually and include such report in their annual proxy statements or annual reports on Form 10-K. We are not subject to such requirement and we have not addressed this in our remuneration committee charter. We disclose the amounts of compensation of our directors on a named basis and the five highest paid employees in our annual reports according to the requirements of Hong Kong Stock Exchange Listing Rules. 4. Nomination Committee 98 While NYSE Standards require U.S. domestic issuers to have only independent directors on their nomination committee, we are not subject to such requirement and our nomination committee consists of two independent non-executive directors and one executive director. NYSE Standards require U.S. domestic issuers to address in their nomination committee charters matters regarding committee member removal and committee structure and operations (including authority to delegate to subcommittees). We are not subject to such requirement and we have not addressed this in our nomination committee charter. NYSE Standards require U.S. domestic issuers to adopt and disclose corporate governance guidelines. They must state in their annual proxy statements or annual reports that such corporate governance guidelines are available on their website and in print form to any shareholder who requests it. We are not subject to such requirement. We have adopted a set of corporate governance guidelines in accordance with the Hong Kong Stock Exchange Listing Rules, including a code of ethics, to govern various aspects of our corporate governance. We have posted the code of ethics on our website. D. EMPLOYEES See "Item 4--Information on the Company--Business Overview--Employees and Employee Benefits." E. SHARE OWNERSHIP We have adopted the following share option schemes for the grant of options to our directors, senior management and other eligible grantees: 1. Pre-Global Offering Share Option Scheme (as defined below); 2. 2001 Share Option Scheme (as defined below); 3. 2002 Share Option Scheme (as defined below); and 4. 2005 Share Option Scheme (as defined below). Under these share option schemes, the remuneration committee of our board of directors had, and will, from time to time propose for our board's approval for the recipient of and the number of shares underlying each option. The maximum aggregate number of shares (including those that could be substituted for under the Pre-Global Offering Share Option Scheme, the 2001 Share Option Scheme, the 2002 Share Option Scheme and the 2005 Share Option Scheme) which may be granted shall not exceed 10% of our total issued share capital as of December 31, 2005, being the date on which our shareholders approved the 2005 Share Option Scheme, excluding shares issued upon exercise of options granted under these schemes from time to time. Pre-Global Offering Share Option Scheme On February 4, 2001, we adopted a pre-global offering share option scheme or the Pre-Global Offering Share Option Scheme. Pursuant to the Pre-Global Offering Share Option Scheme: 1. options for an aggregate of 23,100,000 shares have been granted; 2. the subscription price per share is HK$1.19; and 3. the period during which an option may be exercised is as follows: (a) 50% of the rights to exercise the options shall vest 18 months after the date of the grant; and (b) 50% of the rights to exercise the options shall vest 30 months after the date of the grant. 99 The exercise periods for options granted under the Pre-Global Offering Share Option Scheme shall end not later than 10 years from March 12, 2001. No further options may be granted under the Pre-Global Offering Share Option Scheme. 2001 Share Option Scheme On February 4, 2001, we adopted a share option scheme, or the 2001 Share Option Scheme for the purposes of recognizing the contribution that certain individuals had made to our company and attracting and retaining the best available personnel to our company. Pursuant to the 2001 Share Option Scheme: 1. options for an aggregate of 44,100,000 shares have been granted; 2. the subscription price per share is HK$1.232; and 3. the period during which an option may be exercised is as follows: (a) one-third of the rights to exercise the options shall vest on the first anniversary of the date of the grant; (b) one-third of the rights to exercise the options shall vest on the second anniversary of the date of the grant; and (c) one-third of the rights to exercise the options shall vest on the third anniversary of the date of the grant. The exercise periods for options granted under the 2001 Share Option Scheme shall end not later than 10 years from August 27, 2001. In view of the amendments to the relevant provisions of Hong Kong Stock Exchange Listing Rules regarding the requirements of share option schemes of a Hong Kong listed company effective on September 1, 2001, no further options will be granted under the 2001 Share Option Scheme. 2002 Share Option Scheme In June 2002, we adopted a new share option scheme, or the 2002 Share Option Scheme. Under the 2002 Share Option Scheme, our directors may, at their discretion, invite employees, including executive directors, of our company or any of our subsidiaries, to take up options to subscribe for our shares. The maximum number of shares which may be granted under the 2002 Share Option Scheme to any individual in any 12-month period up to the next grant shall not exceed 1% of our total issued share capital from time to time. According to the 2002 Share Option Scheme, the consideration payable by a grantee for the grant of an option will be HK$1.00. The subscription price of a share payable by a grantee upon the exercise of an option is determined by our directors at their discretion at the date of grant, except that such price may not be set below a minimum price which is the highest of: 1. the nominal value of our share on the date of the grant of the option; 2. the average closing price of the shares on the HKSE as stated in the HKSE's quotation sheets for the five trading days immediately preceding the date of grant of the option; and 3. the closing price of the shares on the HKSE as stated in the HKSE's quotation sheets on the date of grant of the option. 100 On February 24, 2003, our board of directors approved to grant options in respect of 42,050,000 shares to our directors and senior management under the 2002 Share Option Scheme. The exercise price for such options is HK$2.108 per share. The closing market price immediately before the date on which such options were granted was HK$2.11 per share. Such options granted under the 2002 Share Option Scheme may be exercised, in whole or in part, in accordance with the following vesting schedule: 1. one-third of the rights to exercise the options shall vest on the first anniversary of the date of the grant; 2. one-third of the rights to exercise the options shall vest on the second anniversary of the date of the grant; and 3. one-third of the rights to exercise the options shall vest on the third anniversary of the date of the grant. The exercise periods for the above options granted under the 2002 Share Option Scheme shall end not later than 10 years from February 24, 2003. On February 5, 2004, our board of directors approved a grant of options in respect of 50,700,000 shares to our directors and senior management under the 2002 Share Option Scheme. The exercise price for such options is HK$3.152 per share. The closing market price immediately before the date on which such options were granted was HK$3.146 per share. Such options granted under the 2002 Share Option Scheme may be exercised, in whole or in part, in accordance with the following vesting schedule: 1. one-third of the rights to exercise the options shall vest on the first anniversary of the date of the grant; 2. one-third of the rights to exercise the options shall vest on the second anniversary of the date of the grant; and 3. one-third of the rights to exercise the options shall vest on the third anniversary of the date of the grant. The exercise periods for the above options granted under the 2002 Share Option Scheme shall end not later than 10 years from February 5, 2004. On August 31, 2005, our board of directors approved a grant of options in respect of 65,870,000 shares to our directors and senior management under the 2002 Share Option Scheme. The exercise price of such options is HK$5.62 per share. The closing market price immediately before the date on which such options were granted was HK$5.75 per share. Such options granted under the 2002 Share Option Scheme may be exercised, in whole or in part, in accordance with the following vesting schedule: 1. one-third of the rights to exercise the options shall vest on the first anniversary of the date of the grant; 2. one-third of the rights to exercise the options shall vest on the second anniversary of the date of the grant; and 3. one-third of the rights to exercise the options shall vest on the third anniversary of the date of the grant. The exercise periods for the above options granted under the 2002 Share Option Scheme shall end not later than 10 years from August 31, 2005. 101 2005 Share Option Scheme We had undertaken a review of the 2002 Share Option Scheme in 2005 and noted that certain provisions could be clarified and improved. Accordingly, our board had proposed, and on December 31, 2005, we adopted a new share option scheme, or the 2005 Share Option Scheme and terminated the 2002 Share Option Scheme. Upon termination of the 2002 Share Option Scheme, no further options may be granted under the 2002 Share Option Scheme, but in all other respects the provisions of the 2002 Share Option Scheme shall remain in force. The outstanding options under the 2002 Share Option Scheme shall continue to be subject to the provisions of the 2002 Share Option Scheme, and the adoption of the 2005 Share Option Scheme will not in any way affect the terms of the exercise of such outstanding options. Under the 2005 Share Option Scheme, our board will have the authority to grant options to subscribe for shares to our directors, officers and employees and or of our subsidiaries, and any other persons who in sole discretion of our board have contributed or will contribute to our group. Unless approved by our shareholders, the total number of shares issued and to be issued upon exercise of the options granted to each individual (including exercised and unexercised options) under the 2005 Share Option Scheme or any other share option scheme adopted by us, in any 12 months period, must not exceed 1% of the shares in issue. According to the 2005 Share Option Scheme, the consideration payable by a grantee for the grant of an option will be HK$1.00. The subscription price of a share payable by a grantee upon the exercise of an option will be determined by our directors at their discretion at the date of the grant, except that such price may not be set below a minimum price which is the highest of: 1. the nominal value of our share on the date of the grant of the option; 2. the average closing price of the shares on the HKSE as stated in the HKSE's quotation sheets for the five trading days immediately preceding the date of the grant of the option; and 3. the closing price of the shares on the HKSE as stated in the HKSE's quotation sheet on the date of the grant of the option. The period within which the options must be exercised, as well as any minimum holding period or performance targets which apply to the options, will be specified by our board at the time of grant. The exercise periods for options granted under the 2005 Share Option Scheme shall end not later than 10 years from the date of the grant of the option. During the year, no options have been granted or exercised under the 2005 Share Option Scheme. As of December 31, 2005, our directors and employees had the following personal interests in options to subscribe for shares granted under our share option schemes: Number of shares involved in the options outstanding as of ------------------------------- ------------------------------------- Closing price per share immediately before the Exercise December 31, date of Price Name of Grantee January 1, 2005 2005 Date of Grant Date of Expiration*** grant (HK$)** (HK$) --------------- --------------- ------------ ----------------- --------------------- ------------- -------- Directors: Chengyu Fu 1,750,000 1,750,000 March 12, 2001 March 12, 2011 1.23 1.19 1,750,000 1,750,000 August 27, 2001 August 27, 2011 1.46 1.232 1,150,000 1,150,000 February 24, 2003 February 24, 2013 2.09 2.108 2,500,000 2,500,000 February 5, 2004 February 5, 2014 3.13 3.152 102 - 3,500,000 August 31, 2005 August 31, 2015 5.75 5.62 Han Luo 1,400,000 1,400,000 March 12, 2001 March 12, 2011 1.23 1.19 1,150,000 1,150,000 August 27, 2001 August 27, 2011 1.46 1.232 1,150,000 1,150,000 February 24, 2003 February 24, 2013 2.09 2.108 1,150,000 1,150,000 February 5, 2004 February 5, 2014 3.13 3.152 - 1,610,000 August 31, 2005 August 31, 2015 5.75 5.62 Longsheng Jiang* 1,400,000 1,400,000 March 12, 2001 March 12, 2011 1.23 1.19 1,150,000 1,150,000 August 27, 2001 August 27, 2011 1.46 1.232 1,150,000 766,700 February 24, 2003 February 24, 2013 2.09 2.108 1,150,000 383,300 February 5, 2004 February 5, 2014 3.13 3.152 Shouwei Zhou 1,400,000 1,400,000 March 12, 2001 March 12, 2011 1.23 1.19 1,750,000 1,750,000 August 27, 2001 August 27, 2011 1.46 1.232 1,750,000 1,750,000 February 24, 2003 February 24, 2013 2.09 2.108 1,750,000 1,750,000 February 5, 2004 February 5, 2014 3.13 3.152 - 2,450,000 August 31, 2005 August 31, 2015 5.75 5.62 Xinghe Cao - 800,000 August 31, 2005 August 31, 2015 5.75 5.62 Zhenfang Wu - 800,000 August 31, 2005 August 31, 2015 5.75 5.62 Guangqi Wu - 1,610,000 August 31, 2005 August 31, 2015 5.75 5.62 Hua Yang 1,150,000 1,150,000 March 12, 2001 March 12, 2011 1.23 1.19 1,150,000 1,150,000 August 27, 2001 August 27, 2011 1.46 1.232 1,150,000 1,150,000 February 24, 2003 February 24, 2013 2.09 2.108 1,150,000 1,150,000 February 5, 2004 February 5, 2014 3.13 3.152 - 1,610,000 August 31, 2005 August 31, 2015 5.75 5.62 Sung Hong Chiu 1,150,000 1,150,000 February 5, 2004 February 5, 2014 3.13 3.152 Evert Henkes 1,150,000 1,150,000 February 5, 2004 February 5, 2014 3.13 3.152 Erwin 1,150,000 0 February 5, 2004 February 5, 2014 3.13 3.152 Schurtenberger* Kenneth S Courtis 1,150,000 1,150,000 February 5, 2004 February 5, 2014 3.13 3.152 Employees: Other Employees 6,550,000 4,850,000 March 12, 2001 March 12, 2011 1.23 1.19 22,650,000 19,150,000 August 27, 2001 August 27, 2011 1.46 1.232 26,500,000 21,999,900 February 24, 2003 February 24, 2013 2.09 2.108 35,850,000 30,783,400 February 5, 2004 February 5, 2014 3.13 3.152 - 49,500,000 August 31, 2005 August 31, 2015 5.75 5.62 --------------------- * Mr. Longsheng Jiang retired as our Executive Director with effect from June 1, 2005 and Dr. Erwin Schurtenberger resigned as our Independent Non-executive Director with effect from April 1, 2005. ** Adjustment has been made to take account of the subdivision of issued and unissued shares of HK$0.10 each into five shares of HK$0.02 each effective on March 17, 2004. *** The share options are only exercisable by the grantees upon the vesting of such share options. As of June 6, 2006, 2,300,100 options granted under our share option schemes have been exercised. The weighted average closing price of our shares on the day immediately preceding the exercise of the options was HK$4.04. On April 1, 2005, Dr. Erwin Schurtenberger resigned from our board. He also surrendered the share options we granted to him upon resignation. The share options exercised during the year ended December 31, 2005 resulted in the issue of 2,300,100 ordinary shares and new share capital of Rmb 49,000 and share premium of Rmb 4,451,000. No share options had been cancelled during the year ended December 31, 2005. As of December 31, 2005, we had 169,063,300 share options outstanding under these share option schemes which represented approximately 0.4% of our shares in issues as of that date. For further details about our share option schemes, see notes 11 and 29 to our consolidated financial statements attached to this annual report. 103 As of June 6, 2006, none of our directors and employees owned 1% or more of our shares including the shares underlying the stock options granted as of that date.

RELATED PARTY TRANSACTIONS Overview We regularly enter into transactions with related parties, including CNOOC, its subsidiaries and associates, as defined under the Hong Kong Stock Exchange Listing Rules. Since CNOOC indirectly owns an aggregate of approximately 66.41% of our issued share capital, some of these transactions constitute connected transactions under the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited, or the Hong Kong Stock Exchange Listing Rules, and are regulated by the Hong Kong Stock Exchange. Under the Hong Kong Stock Exchange Listing Rules, many of these connected transactions normally would require full disclosure and the prior approval of our independent shareholders. However, since the connected transactions are carried out in the ordinary and usual course of business and occur on a regular basis on normal commercial terms and on terms that are fair and reasonable as far as our shareholders are concerned, the Hong Kong Stock Exchange has granted us a waiver from strict compliance with requirements of the Hong Kong Stock Exchange Listing Rules for the period from January 1, 2003 to December 31, 2005, and we have also obtained independent shareholders' approval at our extraordinary general meeting on December 31, 2005 for the continuing connected transactions for the period from January 1, 2006 to December 31, 2007. The continuing connected transactions are newly categorized into different categories, and each category of connected transactions are subject to annual caps and other conditions as specified below. We originally obtained a waiver from the Hong Kong Stock Exchange on April 3, 2001, shortly after our shares were listed on the Hong Kong Stock Exchange. This waiver expired on December 31, 2002, and we renewed the waiver with the Hong Kong Stock Exchange on January 7, 2003. The renewed 104 waiver covers the period from January 1, 2003 to December 31, 2005. Following the amendments to the Hong Kong Stock Exchange Listing Rules in March 2004, waivers for connected transactions from the Hong Kong Stock Exchange are no longer required, and we are only required to obtain independent shareholders' approval for continuing connected transactions. Accordingly, we obtained independent shareholders' approval for our continuing connected transactions with CNOOC, its subsidiaries and associates for the period from January 1, 2006 to December 31, 2007 using a new categorization. Existing Categories of Connected Transactions Our ongoing connected transactions in respect of which we were granted a waiver for the period from January 1, 2003 to December 31, 2005 consist of the following eight categories: o Contracts with foreign petroleum companies; o Trademark license agreements; o Lease agreement in respect of the Nanshan terminal; o Provision of materials, utilities and ancillary services; o Technical services; o Research and development services; o Lease and property management services; and o Sales of crude oil, condensate oil and liquefied petroleum gas. Contracts with foreign petroleum companies. In preparation for our initial public offering, CNOOC transferred to us all of its rights and obligations under all existing and any future production sharing contracts with various international oil and gas companies. As required by PRC law, CNOOC retained certain administrative functions and will remain a party to the production sharing contracts. PRC law requires CNOOC, which is a State-owned entity, to negotiate and conclude an initial production sharing contract with a foreign partner offshore China. New production sharing contracts continue to be entered into between CNOOC and foreign partners, primarily through bidding organized by CNOOC and, to a lesser extent, through direct negotiation. Trademark license agreements. CNOOC has licensed to us two "CNOOC" trademarks under non-exclusive license agreements that will expire on September 8, 2008. We paid a nominal amount of Rmb 1,000 for each of the trademarks. The registrations for the two trademarks will expire on December 6, 2008 and April 20, 2009, respectively. CNOOC has undertaken that so long as it is our controlling shareholder, it will renew the trademark registrations to enable us to continue using them without any additional consideration. Lease agreement in respect of the Nanshan Terminal. Under an agreement dated September 9, 1999, CNOOC has granted us the right to use the Nanshan Terminal, Yacheng 13-1, free-of-charge for a period of 20 years. We use the property to process natural gas. Provision of materials, utilities and ancillary services. Various affiliates of CNOOC provide us with the use of certain facilities and ancillary services and products, including: o materials for offshore oil and gas production (including cement, diesel oil, mud, fuels, barite and paint); o oil and gas production labor services; o warehousing and storage; 105 o road transportation services; o telecommunication and network services; o wharf services; o construction services, including the construction of roads, piers, buildings, plants and embankment; o major equipment maintenance and repair works; o medical, child care and social welfare services; o water, electricity and heat supply; o security and fire services; technical training; accommodation; o repair and maintenance of buildings; and o catering services. Under agreements between these affiliates of CNOOC and us, the facilities and ancillary products and services are to be provided at: (i) state-prescribed prices; or (ii) where there is no state-prescribed price, market prices, including the local or national market prices or the prices at which CNOOC's affiliates previously provided the relevant materials, utilities and ancillary services to independent third parties; or (iii) when neither (i) nor (ii) is applicable, the cost to CNOOC's associates of providing the relevant materials, utilities and ancillary services, including the cost of sourcing or purchasing from third parties, plus a margin of not more than 5%, before any applicable taxes. The prices, volumes and other terms of the agreements are reviewed by the parties annually. If any of the terms are amended, the parties must enter into a supplemental agreement no later than 60 days prior to the end of the financial year preceding the financial year in which the amendment takes effect. If the parties fail to reach an agreement by then, the existing terms of the supply agreement will continue to apply until the parties agree on the terms of the supplemental agreement. We have undertaken to the Hong Kong Stock Exchange that we will comply with the provisions of the Hong Kong Stock Exchange Listing Rules with respect to any supplemental agreements. For the years ended December 31, 2003, 2004 and 2005, the amounts we paid to affiliates of CNOOC for these services were approximately Rmb 1,018 million, Rmb 1,296 million and Rmb 2,996 million, respectively, representing 2.5%, 2.3% and 4.3%, respectively, of our total revenues in that year. Technical services. Various affiliates of CNOOC, including China Oilfield Services Limited and Offshore Oil Engineering Company Limited, provide us with technical services for our offshore oil and gas production activities, including: o offshore drilling; o ship tugging, oil tanker transportation and security services; o well surveys, well logging, well cementing and other related technical services; 106 o collection of geophysical data, ocean geological prospecting, and data processing; o platform fabrication service and maintenance; and o design, construction, installation and test of offshore and onshore production facilities. For the years ended December 31, 2003, 2004 and 2005, the amounts we paid to affiliates of CNOOC for these services totaled approximately Rmb 3,828 million, Rmb 6,362 million and Rmb 6,651 million, respectively, representing 9.3%, 11.5% and 9.6%, respectively, of our total revenue in that year. We generally conduct an open bidding process to select these services providers and the charges for these services are based on arm's-length negotiations between the parties and reflect considerations such as volume of sales, length of contracts, overall customer relationship and other market factors. Research and development services. Various affiliates of CNOOC, including China Offshore Oil Research Center, have been providing us with research and development services, including: o geophysical exploration services; o seismic data processing; o comprehensive exploration research services; and o information technology services. In July 2003, we established our own research center department, CNOOC China Limited Research Center, to undertake most of our research and development activities. In March 2006, we established CNOOC China Limited Beijing Research Center as a branch. During the years ended December 31, 2003, 2004 and 2005, we paid approximately Rmb 56 million, Rmb 8 million and Rmb 8 million, respectively, to China Offshore Oil Research Center for its provision of general research and development services. We occasionally also hired research institutes, including China Offshore Oil Research Center, through an open bidding process for specific research and development projects. Lease and property management services. We have entered into lease and property management agreements with CNOOC and its affiliates for premises located in Beijing, Tianjin, Zhanjiang, Shanghai and Shenzhen in the PRC and in Singapore. Most of the premises are necessary for our operations, and the agreements are based on normal commercial terms. For the years ended December 31, 2003, 2004 and 2005, the aggregate rentals and management fees payable by us to CNOOC and its affiliates were approximately Rmb 57 million, Rmb 77 million and Rmb 77 million, respectively. Sales of crude oil, condensate oil and liquefied petroleum gas. We sell crude oil, condensate oil and liquefied petroleum gas to affiliates of CNOOC that engage in the downstream petroleum business. The prices for these products are based on prices in the international market. For the years ended December 31, 2003, 2004 and 2005, the affiliates of CNOOC paid us approximately Rmb 8,324 million, Rmb 13,946 million and Rmb 26,576 million, respectively, representing approximately 20.3%, 25.3% and 38.3% of our total revenues for the respective periods.

New Categories of Continuing Connected Transactions In order to present a more coherent, logical and understandable picture to shareholders, and also to enable our company to monitor the status of connected transactions following each category more effectively going forward, we adopted a new categorization for continuing connected transactions, and obtained independent shareholders' approval at our extraordinary general meeting on December 31, 2005. The new categorization of continuing connected transactions, which are discloseable under the Hong Kong Stock Exchange Listing Rules and applicable to our company for the period from January 1, 2006 to December 31, 2007, are set out below: o Provision of exploration, oil and gas development, oil and gas production as well as marketing, management and ancillary services by CNOOC and/or its associates to us; o Provision of management, technical, facilities and ancillary services, including the supply of materials from us to CNOOC and/or its associates; o Sales of petroleum and natural gas products by us to CNOOC and/or its associates.

For further information regarding related party transactions, see note 27 to our consolidated financial statements attached to this annual report. C. INTERESTS OF EXPERTS AND COUNSEL Not applicable. ITEM 8. FINANCIAL INFORMATION 113 A. CONSOLIDATED STATEMENTS AND OTHER FINANCIAL INFORMATION See pages beginning on page F-1 following Item 19. Legal Proceedings We are not a defendant in any material litigation, claim or arbitration, and we know of no pending or threatened proceeding which would have a material adverse effect on our financial condition. Dividend Distribution Policy We intend to declare and pay dividends in the future. The payment and the amount of any dividends will depend on our earnings, capital expenditure requirements, financial conditions, future prospects and other factors which our directors may consider relevant. In addition, CNOOC, as our controlling shareholder, will be able to influence our dividend policy. Holders of our shares will be entitled to receive such dividends declared by our board of directors pro rata according to the amounts paid up or credited as paid up on the shares. Subject to the factors described above, we currently intend to pursue a dividend policy consistent with other international oil and gas exploration and production companies. Based on current share prices and dividends of international oil and gas exploration and production companies, we currently intend to target an initial dividend yield of approximately 1% to 3%. Dividends may be paid only out of our distributable profits as permitted under Hong Kong law, which does not restrict the payment of dividends to nonresident holders of our securities. To the extent profits are distributed as dividends, such portion of profits will not be available to be reinvested in our operations. Holders of our ADSs will be entitled to receive dividends, subject to the terms of the deposit agreement, to the same extent as holders of our shares, less the fees and expenses payable under the deposit agreement. Cash dividends will be paid to the depositary in Hong Kong dollars and, will be converted by the depositary into U.S. dollars and paid to holders of ADSs. Stock dividends, if any, will be distributed to the depositary and will be distributed by the depositary, in the form of additional ADSs, to holders of the ADSs. Following the reorganization of CNOOC and our establishment as a separate legal entity in October 1999, we paid a dividend of Rmb 1,045.4 million in 1999 and declared and paid a final dividend of Rmb 6,426.4 million in 2000. In 2001, 2002 and 2003, we declared and paid dividends totaling Rmb 871.1 million, Rmb 2,265.1 million and Rmb 5,403.7 million, respectively. In 2004, we declared dividends totaling Rmb 6,101.4 million and paid dividends totaling Rmb 6,091.4 million. The difference between the amount of dividends declared and paid in 2004 was because that we repurchased and canceled some of our shares in 2004. Out of the total dividends declared and paid in 2004, Rmb 2,617.5 million (US$316.3 million) was attributable to a special interim dividend to replace the 2003 final dividend and final special dividend proposed by our board of directors in 2003. In 2005, we declared and paid dividends totaling Rmb 7,772.2 million (US$963.1 million). The amount of dividends we paid historically is not indicative of the dividends that we will pay in the future. Substantially all our dividend payments result from dividends paid to us by CNOOC China Limited. CNOOC China Limited must follow the laws and regulations of the PRC and its articles of association in determining its dividends. As a wholly foreign owned enterprise in China, CNOOC China has to provide for a reserve fund and staff and workers' bonus and welfare fund, each of which is appropriated from net profit after taxation but before dividend distribution according to the prevailing accounting rules and regulations in the PRC. CNOOC China is required to allocate at least 10% of its net profit to the reserve fund until the balance of this fund has reached 50% of its registered capital. Appropriations to the staff and workers' bonus and welfare fund, which are determined at the discretion of CNOOC China's directors, are charged to expense as incurred in the consolidated financial statements, which were prepared under Hong Kong GAAP. None of CNOOC China's contributions to these statutory funds may be used for dividend purposes. 114 For the years ended December 31, 2003, 2004 and 2005, CNOOC China Limited made the following appropriations to the statutory reserves: For the year ended For the year ended For the year ended December 31, 2003 December 31, 2004 December 31, 2005 ----------------- ----------------- ----------------- Percentage Rmb Percentage Rmb Percentage Rmb of Net Profits (in millions) of Net Profits (in millions) of Net Profits (in millions) -------------- ------------- -------------- ------------- -------------- ------------- Reserve fund ............... 10% 818.1 10% 1,363.1 10% 2,268.4 Staff and workers' bonus and welfare fund ............ -- -- -- -- -- -- B. SIGNIFICANT CHANGES First Quarter 2006 Financial and Operating Results During the first quarter of 2006, our unaudited revenues from the sale of oil and gas were Rmb 16.4 billion. Our daily average crude oil production was 383,519 barrels per day during this period, compared to 351,579 barrels per day in 2005, while our daily average natural gas production was 390 million cubic feet per day, compared to 348 million cubic feet per day in 2005. The average net realized price of our crude oil was US$58.13 per barrel during the first quarter of 2006, compared to US$41.73 per barrel in 2005, while the average net realized price of our natural gas was US$3.10 per thousand cubic feet, compared to US$2.92 per thousand cubic feet in 2005. Change of Directors and Management On April 18, 2006, Mr. Yunshi Cao ceased to be our Senior Vice President, General Counsel and Company Secretary. On the same day, Mr. Victor Zhikai Gao was appointed as our Senior Vice President, General Counsel and Company Secretary. On May 24, 2006, Dr. Kenneth S. Courtis retired as an Independent Non-executive Director of our Company in accordance with the retirement provisions in article 97 of our articles of association, following the conclusion of our annual general meeting. On the same day, Dr. Edgar W. K. Cheng was elected by our shareholders as an Independent Non-executive Director. Effective May 25, 2006, the composition of our board committees is set forth in the table below.

At the time of the agreements, the Vendor held 28,999,999,995 of our issued shares and pursuant to the Placing Agreement, the Vendor agreed to place 2,500,000,000 shares in our share capital to independent investors at HK$6.15 per share. Within 14 days of the Placing Agreement, the Vendor will, pursuant to the Subscription Agreement, subscribe for 2,272,727,273 new shares at HK$6.15 per share (the "Subscription"). 115 The Placing Shares represent approximately 6.09% of our issued share capital of 41,054,675,375 shares and approximately 5.77% of our issued share capital as enlarged by the Subscription. The net proceeds from the Subscription of approximately HK$13.78 billion will be used to finance our continuing capital expenditure requirements in relation to the OML 130 in offshore Nigeria, as well as our general working capital needs. As the Subscription was completed before the record date of May 16, 2006 for the 2005 final dividends of HK$0.10 per Share declared by our board of directors on March 24, 2006, the Shares under the Subscription will be entitled to the final dividends. We would therefore be required to pay an amount of additional dividends of HK$227,272,727. As a result, our aggregate final dividends payable for the year ended December 31, 2005 would be HK$4,332,740,265. ITEM 9. THE OFFER AND LISTING Not applicable, except for Item 9.A.4 and Item 9.C. We listed our shares on the Hong Kong Stock Exchange and our ADSs on the New York Stock Exchange in February 2001. Our shares are listed on the Hong Kong Stock Exchange under the stock code "883" and our ADSs are listed on the New York Stock Exchange under the symbol "CEO." On March 17, 2004, our shareholders approved a five-for-one stock split of our shares. The stock split was effected by dividing each of our issued and unissued shares of HK$0.10 each into five shares of HK$0.02 each. The ratio of our American depositary shares listed on the New York Stock Exchange also changed such that each ADS now represents 100 subdivided shares of HK$0.02 each, as opposed to 20 shares of HK$0.10 each prior to the stock split. The following table sets forth, for the periods indicated, the high and low closing prices per share, as reported on the Hong Kong Stock Exchange and adjusted retroactively to reflect the stock split, and per ADS, as reported on the New York Stock Exchange.

ADDITIONAL INFORMATION A. SHARE CAPITAL Not applicable. B. MEMORANDUM AND ARTICLES OF ASSOCIATION We were incorporated with limited liability on August 20, 1999 in Hong Kong under the Companies Ordinance of Hong Kong. Our company registration number in Hong Kong is 685974. Under section three of our memorandum of association, we have the capacity and the rights, powers and privileges of a natural person and in addition and without limit, we may do anything which we are permitted to do by any enactment or rule of law. The following are summaries of provisions of our memorandum of association and articles of association and the Companies Ordinance (Chapter 32 of the Laws of Hong Kong). For further details, you should read our memorandum of association which was filed as an exhibit to our registration statement on Form F-1 (Registration No.333-10862) and our articles of association, as amended, which is filed as an exhibit to this annual report. Issue of Shares Under the Companies Ordinance of Hong Kong, our directors may, without prior approval of the shareholders, offer to allot new shares in our company to existing shareholders pro rata. Our directors may not allot new shares of our company in any other manner without the prior approval of our shareholders in a general meeting. Any approval given at a general meeting shall continue in force from the date of the passing of the resolution until the earliest of: o the conclusion of the next annual general meeting, o the expiration of the period within which the next annual general meeting is required by any applicable laws or our articles of the association to be held, or o the revocation or variation of the authority given under an ordinary resolution of the shareholders, in a general meeting of our company. If such approval is given, the unissued shares of our company shall be at the disposal of the board of directors. Our directors may offer, allot, grant options over or otherwise dispose of the unissued shares to persons at such times and for such consideration and upon such terms and conditions as our directors may determine, subject to the restrictions under the Hong Kong Stock Exchange Listing Rules. In accordance with Hong Kong Stock Exchange Listing Rules, any such approval of the shareholders must be limited to shares with an aggregate nominal value not exceeding 20% of the aggregate value of our share capital in issue as of the date of granting such approval plus the aggregate nominal amount of share capital repurchased by us since the granting of such approval. Dividends Subject to the Companies Ordinance of Hong Kong, the shareholders in a general meeting may declare dividends to be paid to shareholders. However, under our articles of association, dividends cannot be declared in excess of the amount recommended by our board of directors. In addition to dividends declared in a general meeting, our board of directors may declare and pay to the shareholders interim dividends as appear to our board of directors to be justified by our financial position. Our board of directors may also pay any fixed dividend on any shares of our company semi-annually or at other suitable intervals, whenever our financial position, in their opinion, justifies such payment. 117 Winding Up If we are wound up, the liquidator may, with the sanction of a special resolution, divide among our shareholders in specie or in kind the whole or any part of our assets or vest any part of our assets in trustees upon such trusts for the benefit of our shareholders or any of them as the resolution shall provide. Voting Rights Under the Companies Ordinance of Hong Kong, any action to be taken by the shareholders in a general meeting requires the affirmative vote of either an ordinary or a special resolution passed at such meeting. o An ordinary resolution is a resolution passed by the majority of shareholders that are entitled to, and do, vote in person or by proxy at a general meeting; o A special resolution is a resolution passed by not less than 75% of shareholders that are entitled to, and do, vote in person or by proxy at a general meeting. Generally, resolutions of shareholders are passed by ordinary resolution. However, the Companies Ordinance of Hong Kong provides that some matters may only be passed as special resolutions. These matters include, for example: o alteration of the object clause; o alteration of the articles; o change of a company's name; o reduction of share capital; and o voluntary winding up. Voting at any meeting of shareholders is by a show of hands unless a poll is demanded. If voting is by a show of hands, every shareholder who is present at the meeting in person or by proxy has one vote. On a poll, every shareholder who is present in person or by proxy has one vote for every share held or represented by him. A poll may be demanded by: o the chairman of the meeting; o at least three members present in person (or in the case of a member being a corporation, by its duly authorized representative) or by proxy and entitled to vote at the meeting; o any member or members present in person (or in the case of a member being a corporation, by its duly authorized representative) or by proxy and representing in the aggregate not less than 10% of the total voting rights of all members having the right to attend and vote at the meeting; or o any member or members present in person (or in the case of a member being a corporation, by its duly authorized representative) or by proxy and holding shares conferring a right to attend and vote at the meeting on which there have been paid up sums in the aggregate equal to not less than 10% of the total sum paid up on all shares conferring that right. Any action to be taken by the shareholders requires the affirmative vote of the requisite majority of the shares at a meeting of shareholders. There are no cumulative voting rights. Accordingly, the 118 holders of a majority of the shares voting for the election of directors can elect all the directors if they choose to do so. General Meetings We are required to hold an annual general meeting of shareholders each year within 15 months from the date of our last annual general meeting. We may also hold extraordinary general meetings of shareholders from time to time. Our board of directors may convene an extraordinary general meeting at will, and shall on requisition in accordance with the Companies Ordinance of Hong Kong, proceed to convene an extraordinary general meeting. Our annual general meeting and any extraordinary general meeting called for the purpose of passing a special resolution requires at least 21 days' prior notice, and any other general meeting requires at least 14 days' prior notice. The notice must specify the place, day and time of the meeting and, in the case of special business, the general nature of that business. The quorum for a general meeting is two shareholders present in person or by proxy. If within thirty minutes from the time appointed for the meeting a quorum is not present, the meeting, if convened upon requisition in accordance with the Companies Ordinance of Hong Kong, must be dissolved; but in any other case it must stand adjourned to the same day in the next week at the same time and place, or to such other day, time and place as the Chairman of the meeting may determine. If at such adjourned meeting a quorum is not present within thirty minutes from the time appointed for the meeting, the member or members present in person or by proxy shall be a quorum and may transact the business for which the meeting is called. Modification of Rights Subject to the Companies Ordinance of Hong Kong, any of the rights attaching to any class of shares, unless otherwise provided for by the terms of issue of the shares of that class, may be varied or abrogated with the written consent of the holders of not less than 75% of the issued shares of that class or with the sanction of a special resolution passed at a separate general meeting of the holders of shares of that class. Borrowing Powers Our board of directors may exercise all the powers of our company to borrow money and to mortgage or charge all or any part of our undertaking, property and assets, whether present or future, and uncalled capital. Our board of directors may issue debentures, debenture stock, bonds or other securities of our company, whether outright or as collateral security for any debt, liability or obligation of our company or of any third party. These borrowing powers are subject to variation by a special resolution of our company. Interested Transactions Subject to the exceptions described below, none of our directors may vote on any contract, arrangement or proposal in which the director or any of his or her associates is materially interested. For this purpose, existence of material interest is presumed if a company, in which the director and/or his or her associates beneficially own 5% or more of any class of its shares or voting rights, is materially interested in the transaction. Our directors may, however, vote on the following matters: o any contract or arrangement to give security or indemnity to the director or his or her associates for money lent or obligations undertaken by such director or his or her associates at the request of or for the benefit of our company or subsidiaries; o any contract or arrangement to give security or indemnity to a third party for our debts or debts of our subsidiaries for which such director or his or her associates assumed responsibility by giving guarantee or security; 119 o any contract or arrangement concerning offering of securities by us (or any company which we may promote or be interested in purchasing) for which the director or his or her associates participate in the underwriting or sub-underwriting; o any contract or arrangement in which the director or his or her associates are interested only by virtue of their interest in our securities; o any contract or arrangement concerning any other company in which the director or his or her associates are interested as an officer or executive or a shareholder in which the director or his or her associates are beneficially interested in shares of that company other than a company in which they in aggregate beneficially own more than 5% of the issued shares of any class or voting rights; o any proposal or arrangement concerning employee benefits that do not provide privileges to our directors or their associates, including employee share schemes and retirement, death or disability benefits schemes; and o any proposal or arrangement concerning the adoption, modification or operation of any employees' share scheme involving the issue or grant of options over shares or other securities by us to, or for the benefit of, our employees or employees of our subsidiaries under which the director or his or her associates may benefit. C. MATERIAL CONTRACTS Incorporated by reference to our registration statement on Form F-1 (Registration No.333-10862) and annual reports on Form 20-F for fiscal years 2003, 2004 and 2005 (File No.1-14966), to which most of our current material contracts were filed as exhibits. For additional information on our material contracts, see "Item 7--Major Shareholders and Related Party Transactions--Related Party Transactions" and "Item 19--Exhibits." D. EXCHANGE CONTROLS A portion of our Renminbi revenue may need to be converted into other currencies by our wholly owned principal operating subsidiary in the PRC, CNOOC China Limited, to meet our foreign currency obligations. We have substantial requirements for foreign currency, including: o debt service on foreign currency denominated debt; o overseas acquisitions of oil and gas properties; o purchases of imported equipment; and o payment of dividends declared in respect of shares held by international investors. CNOOC China Limited may undertake current account foreign exchange transactions without prior approval from the State Administration for Foreign Exchange. It has access to current account foreign exchange so long as it can produce commercial documents evidencing such transactions and provided that they are processed through certain banks in China. Foreign exchange transactions under the capital account, including principal payments with respect to foreign currency denominated obligations, will be subject to the registration requirements of the State Administration for Foreign Exchange. Since 1994, the conversion of Renminbi into Hong Kong and United States dollars has been based on rates set by the People's Bank of China, which are set daily based on the previous day's PRC interbank foreign exchange market rate and current exchange rates on the world financial markets. The PRC government has stated publicly that it intends to make Renminbi freely convertible in the future. On July 21, 2005, China reformed its foreign exchange regime by moving into a managed floating exchange rate system based on market supply and demand with reference to a basket of currencies. Renminbi 120 would no longer be pegged to the U.S. dollar. From that day to December 31, 2005, Renminbi appreciated about 2.5% against the U.S. dollar. However, we cannot predict when the PRC government will allow free conversion of Renminbi into foreign currencies. Changes in the PRC government's currency policies may lead to further fluctuations in the exchange rates for the conversion of Renminbi into foreign currencies which could have an uncertain effect on our business and operating results. Since the benchmark oil and gas prices are usually in U.S. dollars, the appreciation of Renminbi against U.S. dollars will decrease our revenues derived from oil and gas sales while such effects may be partially offset by decreases in the costs of imported equipment denominated in U.S. dollar and our debt servicing payments in U.S. dollar. Except for our Yen-denominated debts, we do not hedge exchange rate fluctuations between the Renminbi and foreign currencies and currently have no plans to do so. For further information on foreign exchange risks, foreign exchange rates and hedging activities, see "Item 3--Key Information--Selected Financial Data" and "Item 11--Qualitative and Quantitative Disclosure about Market Risk." E. TAXATION The taxation of income and capital gains of holders of our shares or ADSs is subject to the laws and practices of Hong Kong and of jurisdictions in which holders of our shares or ADSs are resident or otherwise subject to tax. The following is a summary of taxation provisions that are anticipated to be material based on current law and practice, is subject to change and does not constitute legal or tax advice. The discussion does not deal with all possible tax consequences relating to an investment in our shares or ADSs. In particular, the discussion does not address the tax consequences under state, local and other laws, such as non-Hong Kong and non-U.S. federal laws. Accordingly, we urge you to consult your tax adviser regarding the tax consequences of an investment in our shares and ADSs. The discussion is based upon laws and relevant interpretations in effect as of the date of this annual report, all of which are subject to changes. There is no reciprocal tax treaty in effect between Hong Kong and the United States. Hong Kong Tax on Dividends Under the current practices of the Hong Kong Inland Revenue Department, no tax is payable in Hong Kong in connection with dividends paid by us. Profits Tax No tax is imposed in Hong Kong in respect of capital gains from the sale of property, such as the shares and ADSs. Trading gains from the sale of property by persons carrying on a trade, profession or business in Hong Kong where such gains are derived from or arise in Hong Kong from such trade, profession or business will be chargeable to Hong Kong profits tax which is currently imposed at the rate of 17.5% on corporations and at a maximum rate of 16% on individuals. Gains from sales of the shares effected on the Hong Kong Stock Exchange will be considered to be derived from or arise in Hong Kong. Liability for Hong Kong profits tax would thus arise in respect of trading gains from sales of shares or ADSs realized by persons carrying on a business of trading or dealing in securities in Hong Kong. Stamp Duty Hong Kong stamp duty, currently charged at the rate of HK$1.00 per HK$1,000 or part thereof on the higher of the consideration for or the value of the shares, will be payable by the purchaser on every purchase and by the seller on every sale of shares. For example, a total of HK$2.00 per HK$1,000 or part thereof is currently payable on a typical sale and purchase transaction involving shares. In addition, a fixed duty of HK$5 is currently payable on any instrument of transfer of shares. The withdrawal of shares upon the surrender of ADRs, and the issuance of ADRs upon the deposit of shares, will also attract stamp duty at the rate described above for sale and purchase transactions unless the withdrawal or deposit does not result in a change in the beneficial ownership of the shares under Hong Kong law. The issuance of the ADRs upon the deposit of shares issued directly to the depositary or for the account of the 121 depositary does not attract stamp duty. No Hong Kong stamp duty is payable upon the transfer of ADSs outside Hong Kong. Estate Duty The shares are Hong Kong property under Hong Kong law, and accordingly such shares may be subject to estate duty on the death of the beneficial owner of such shares, regardless of the place of the owner's residence, citizenship or domicile. We cannot assure that the Hong Kong Inland Revenue Department will not treat the ADRs as Hong Kong property that may be subject to estate duty on the death of the beneficial owner of the ADR even if the ADRs are located outside Hong Kong at the date of such death. Hong Kong estate duty is imposed on a progressive scale from 5% to 15%. The rate of and the threshold for estate duty has, in the past, been adjusted on a fairly regular basis. No estate duty is payable when the aggregate value of the dutiable estate does not exceed HK$7.5 million, and the maximum rate of duty of 15% applies when the aggregate value of the dutiable estate exceeds HK$10.5 million. The Hong Kong Government is considering abolishing estate duty in Hong Kong. United States Federal Income Tax Considerations The following is a summary of United States federal income tax considerations that are anticipated to be material for U.S. Holders, as defined below. This summary is based upon existing United States federal income tax law, which is subject to change, possibly with retroactive effect. This summary does not discuss all aspects of United States federal income taxation which may be important to particular investors in light of their individual investment circumstances, such as investors subject to special tax rules including: partnerships, financial institutions, insurance companies, broker-dealers, tax-exempt organizations, and, except as described below, non-U.S. Holders, or to persons that will hold our shares or ADSs as part of a straddle, hedge, conversion, or constructive sale transaction for United States federal income tax purposes or that have a functional currency other than the United States dollar, all of whom may be subject to tax rules that differ significantly from those summarized below. In addition, this summary does not discuss any foreign, state, or local tax considerations. This summary assumes that investors will hold our shares or ADSs as "capital assets" (generally, property held for investment) under the United States Internal Revenue Code. Each prospective investor is urged to consult its tax advisor regarding the United States federal, state, local, and foreign income and other tax considerations of the purchase, ownership, and disposition of our shares or ADSs. For purposes of this summary, an U.S. Holder is a beneficial owner of shares or ADSs that is for United States federal income tax purposes: o an individual who is a citizen or resident of the United States; o a corporation, partnership or other entity created in or organized under the laws of the United States or any State or political subdivision thereof; o an estate the income of which is includible in gross income for United States federal income tax purposes regardless of its source; o a trust the administration of which is subject to the primary supervision of a United States court and which has one or more United States persons who have the authority to control all substantial decisions of the trust; or o a trust that was in existence on August 20, 1996, was treated as a United States person, for United States federal income tax purposes, on the previous day, and elected to continue to be so treated. A beneficial owner of our shares or ADSs that is not a U.S. Holder is referred to herein as a "Non-U.S. Holder." 122 A foreign corporation will be treated as a "passive foreign investment company" or "PFIC", for United States federal income tax purposes, if 75% or more of its gross income consists of certain types of "passive" income or 50% or more of its assets produce or are held for the production of passive income. Based on our current and projected income, assets, and activities, we presently believe that we are not a PFIC and do not anticipate becoming a PFIC. This is, however, a factual determination made on an annual basis. Because the classification of certain of our interests for United States federal income tax purposes is uncertain and the PFIC rules are subject to administrative interpretation, however, no assurance can be given that we are not or will not be treated as a PFIC. The discussion below under "U.S. Holders-Dividends" and "U.S. Holders-Sale or Other Disposition of Shares or ADSs," assumes that we will not be subject to treatment as a PFIC for United States federal income tax purposes. U.S. Holders For United States federal income tax purposes, a U.S. Holder of an ADS will be treated as the owner of the proportionate interest of the shares held by the depositary that is represented by an ADS and evidenced by such ADS. Accordingly, no gain or loss will be recognized upon the exchange of an ADS for the holders' proportionate interest in the shares. A U.S. Holder's tax basis in the withdrawn shares will be the same as the tax basis in the ADS surrendered therefore, and the holding period in the withdrawn shares will include the period during which the holder held the surrendered ADS. Dividends. Any cash distributions paid by us out of our earnings and profits, as determined under United States federal income tax principles, will be subject to tax as ordinary dividend income and will be includible in the gross income of a U.S. Holder upon receipt. Cash distributions paid by us in excess of our earnings and profits will be treated as a tax-free return of capital to the extent of the U.S. Holder's adjusted tax basis in our shares or ADSs, and after that as gain from the sale or exchange of a capital asset. Dividends paid in Hong Kong dollars will be includible in income in a United States dollar amount based on the United States dollar to Hong Kong dollar exchange rate prevailing at the time of receipt of such dividends by the depositary, in the case of ADSs, or by the U.S. Holder, in the case of shares held directly by such U.S. Holder. U.S. Holders should consult their tax advisors regarding the United States federal income tax treatment of any foreign currency gain or loss recognized on the subsequent conversion of Hong Kong dollars received as dividends to United States dollars. Dividends received on shares or ADSs will not be eligible for the dividends received deduction allowed to corporations. Under current law, "qualified dividend income" received by an individual for taxable years beginning after December 31, 2002 and for taxable years beginning before January 1, 2009 is subject to United States federal income tax rates lower than those applicable to ordinary income. The top federal income tax rate on such qualified dividend income received by an individual is 15% or 5% for those individuals whose incomes fall in the 10 or 15% brackets. Based upon our existing and anticipated future operations and current assets, we believe that we are a "qualified foreign corporation" and that our dividends paid to U.S. Holders who are individuals will be eligible to be treated as "qualified dividend income" provided that such U.S. Holders satisfy applicable holding period requirements with respect to the ADSs and other applicable requirements. Dividends paid by foreign corporations that are classified as PFICs are not eligible to be treated as "qualified dividend income". See "PFIC Considerations" below. Dividends received on shares or ADSs will be treated, for United States federal income tax purposes, as foreign source income. A U.S. Holder may be eligible, subject to a number of complex limitations, to claim a foreign tax credit in respect of any foreign withholding taxes imposed on dividends received on shares or ADSs. U.S. Holders who do not elect to claim a foreign tax credit for federal income tax withheld may instead claim a deduction, for United States federal income tax purposes, in respect of such withholdings, but only for a year in which the U.S. Holder elects to do so for all creditable foreign income taxes. In addition, the United States Treasury has expressed concerns that parties to whom depositary shares are pre-released may be taking actions that are inconsistent with the claiming of foreign tax credits by the holders of ADSs. Accordingly, the analysis of the creditability of foreign withholding taxes could be affected by future actions that may be taken by the United States Treasury. 123 Sale or Other Disposition of Shares or ADSs. A U.S. Holder will recognize capital gain or loss upon the sale or other disposition of shares or ADSs in an amount equal to the difference between the amount realized upon the disposition and the U.S. Holder's adjusted tax basis in such shares or ADSs, as each is determined in U.S. dollars. Any such capital gain or loss will be long-term if the shares or ADSs have been held for more than one year and will generally be United States source gain or loss. The claim of a deduction in respect of a capital loss, for United States federal income tax purposes, may be subject to limitations. If a U.S. Holder receives Hong Kong dollars for any such disposition, such U.S. Holder should consult its tax advisor regarding the United States federal income tax treatment of any foreign currency gain or loss recognized on the subsequent conversion of the Hong Kong dollars to United States dollars. PFIC Considerations If we were to be classified as a PFIC in any taxable year, a U.S. Holder would be subject to special rules generally intended to reduce or eliminate any benefits from the deferral of United States federal income tax that a U.S. Holder could derive from investing in a foreign company that does not distribute all of its earnings on a current basis. In such event, a U.S. Holder of the shares or ADSs may be subject to tax at ordinary income tax rates on (i) any gain recognized on the sales of the shares or ADSs and (ii) any "excess distribution" paid on the shares or ADSs (generally, a distribution in excess of 125% of the average annual distributions paid by us in the three preceding taxable years). In addition, a U.S. Holder may be subject to an interest charge on such gain or excess distribution. Prospective investors are urged to consult their tax advisors regarding the potential tax consequences to them if we are or do become a PFIC, as well as certain elections that may be available to them to mitigate such consequences. Non-U.S. Holders An investment in shares or ADSs by a Non-U.S. Holder will not give rise to any United States federal income tax consequences unless: o the dividends received or gain recognized on the sale of the shares or ADSs by such person is treated as effectively connected with the conduct of a trade or business by such person in the United States as determined under United States federal income tax law, or o in the case of gains recognized on a sale of shares or ADSs by an individual, such individual is present in the United States for 183 days or more and certain other conditions are met. In order to avoid back-up withholding on dividend payments made in the United States, a Non-U.S. Holder of the shares or ADSs may be required to complete, and provide the payer with, an Internal Revenue Service Form W-8BEN, or other documentary evidence, certifying that such holder is an exempt foreign person.

I. SUBSIDIARY INFORMATION Not applicable. ITEM 11. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK Our market risk exposures primarily consist of fluctuations in oil and gas prices, exchange rates and interest rates. Commodity Price Risks We are exposed to fluctuations in prices of crude oil and natural gas. International oil and gas prices are volatile and this volatility has a significant effect on our net sales and net income. We do not hedge market risk resulting from fluctuations in oil and gas prices. See "--Overview" and "Item 3--Key Information--Risk Factors--Risks relating to our business--Our business, revenues and profits fluctuate with changes in oil and gas prices." Currency Risk Our foreign exchange exposure gives rise to market risk associated with exchange rate movements. Substantially all of our oil and gas sales are denominated in Renminbi and U.S. dollars. In the last ten years, the PRC government's policy of maintaining a stable exchange rate and China's ample foreign reserves have contributed to the stability of the Renminbi. On July 21, 2005, China reformed its foreign exchange regime by moving into a managed floating exchange rate system based on market supply and demand with reference to a basket of currencies. Renminbi would no longer be pegged to the U.S. dollar. From that day to December 31, 2005, Renminbi appreciated about 2.5% against the U.S. dollar. However, the Chinese government has not yet determined if or when the exchange rate will be deregulated. Since the benchmark oil and gas prices are usually in U.S. dollars, the appreciation of Renminbi against U.S. dollars will decrease our revenues derived from oil and gas sales while such effects may be partially offset by decreases in the costs of imported equipment denominated in U.S. dollar and our debt servicing payments in U.S. dollar. As of December 31, 2005, the balance of our Yen-denominated loans was only Rmb 37.3 million. Since we have hedged our Yen loans against foreign currency swaps, we do not expect any exchange risk relating to Japanese Yen in the future. For a discussion of our currency risk, see "Item 3--Key Information--Risk Factors--Risks relating to the PRC-- Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition." Interest Rate Risk We are exposed to interest rate risk arising from our loans. An upward fluctuation in interest rates increases the cost of new debt. We may use interest rate swap transactions, from time to time, to hedge our interest rate exposure when considered appropriate, based on existing and anticipated market conditions. As of December 31, 2005, the interest rates for our outstanding debts were fixed. The term of the weighted average balance was approximately eight years. The average interest rate payable by the Group is favorable under the environment of interest rate hike.

CODE OF ETHICS 127 Our board of directors adopted a code of ethics ("Code of Ethics") on August 28, 2003 to provide guidelines to our senior management and directors in legal and ethical matters as well as the sensitivities involved in reporting illegal and unethical matters. The Code of Ethics covers such areas as supervisory rules, insider dealing, market malpractices, conflict of interests, company opportunities, protection and proper use of our assets as well as reporting requirements. All our directors and senior management members are required to familiarize themselves with and follow the Code of Ethics to ensure that our operations are honest and legal. Violations of the rules will be disciplined and serious offences will result in dismissals. We reviewed our Code of Ethics and adopted the revised code of ethics (the "New Code of Ethics") in 2005, as part of our continuing efforts to improve our corporate governance standards. The New Code of Ethics clarified the scope of senior management, and expanded the applicability of prohibitions against insider trading and other market misconduct to any "manager, secretary of, or any other person involved in the management of, a corporation." Other revisions made in the New Code of Ethics are technical or administrative in nature. We have provided all our directors and senior officers with a copy of the New Code of Ethics and require them to comply with the New Code of Ethics, so as to ensure our operation is proper and lawful. We will take disciplinary actions towards any act which is in breach of the New Code of Ethics. Any change or waiver, explicit or implicit, with respect to our code of ethics, must be disclosed to our shareholders either in our annual report or on our internet website, www.cnoocltd.com. ITEM 16C.

Audit Committee's pre-approval policies and procedures The audit committee under our board of directors is responsible for the appointment, compensation and oversight of the work of our independent auditor. In 2003, our audit committee adopted a policy calling for the audit committee's pre-approval for the engagement of independent auditor for audit and permitted non-audit services. Our board of directors has also ratified the policy and procedures. Under this audit committee policy, proposed services may be pre-approved by the audit committee either on an annual basis or on a case-by-case basis. Appendices to the audit committee policy 128 sets forth (1) the audit, audit-related, tax and other services that may be subject to the general annual pre-approval of the audit committee; (2) non-audit services of a routine and recurring nature that may be subject to specific pre-approval from the audit committee on a case-by-case basis; and (3) a list of prohibited non-audit services. The audit committee will periodically review and revise these attached lists based on its subsequent determinations. The audit committee policy also provides for procedures to establish annual fee levels or budgets for pre-approved services and ratios between different categories of pre-approved services. In addition, the audit committee policy contains provisions that deal with compliance, monitoring, reporting and other related matters. During 2005, all of the audit-related services, and all of tax fees paid to our principal accountant were approved by the audit committee. Our principal accountant audited our financial statements for 2005 solely through its full-time, permanent employees, without involvement of its part-time or temporary employees. ITEM 16D.

F-9 Notes to the consolidated financial statements....................... F-10 F-2 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Shareholders of CNOOC Limited (Incorporated in Hong Kong with limited liability) We have audited the accompanying consolidated balance sheets of CNOOC Limited (the "Company") and its subsidiaries (the "Group") as of December 31, 2005 and 2004, and the related consolidated income statements, changes in shareholders' equity and cash flows for each of the three years ended December 31, 2005, 2004 and 2003. These financial statements are the responsibility of the management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States) and Hong Kong Standards on Auditing issued by the Hong Kong Institute of Certified Public Accountants. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. We were not engaged to perform an audit of the Company's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Group as of December 31, 2005 and 2004 and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2005, in conformity with accounting principles generally accepted in Hong Kong ("Hong Kong GAAP"). Accounting principles generally accepted in Hong Kong vary in certain significant respects from accounting principles generally accepted in the United States of America.

The above table lists the subsidiaries of the Company which, in the opinion of the directors, principally affected the results for the year or formed a substantial portion of the net assets of the Group. To give details of other subsidiaries would, in the opinion of the directors, result in particulars of excessive length. 2.1 BASIS OF PREPARATION These financial statements have been prepared in accordance with Hong Kong Financial Reporting Standards ("HKFRSs") (which also include Hong Kong Accounting Standards ("HKASs") and Interpretations) issued by the Hong Kong Institute of Certified Public Accountants ("HKICPA"), accounting principles generally accepted in Hong Kong ("Hong Kong GAAP") and the disclosure requirements of the Hong Kong Companies Ordinance. They have been prepared under the historical cost convention except for available-for-sale investments and derivative financial instruments which have been measured at fair value. These financial statements are presented in Renminbi ("RMB") and all values are rounded to the nearest thousand (RMB'000) except when otherwise indicated. Basis of consolidation The consolidated financial statements include the financial statements of the Company and its subsidiaries for the year ended December 31, 2005. The results of subsidiaries are consolidated from the date of acquisition being the date on which the Group obtains control and continue to be consolidated until the date that such control ceases. All significant intercompany transactions and balances within the Group are eliminated on consolidation. The acquisition of subsidiaries or an interest in a joint venture or associate during the year has been accounted for using the purchase method of accounting. This method involves allocating the cost of the business combinations to the fair value of the assets acquired, and liabilities and contingent liabilities assumed at the date of acquisition. The cost of the acquisition is measured at the aggregate of the fair value of the assets given, equity instruments issued (if any) and liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition. F-12 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 2.2 IMPACT OF NEW AND REVISED HONG KONG FINANCIAL REPORTING STANDARDS ("HKFRSs") The Hong Kong Institute of Certified Public Accountants has issued a number of new Hong Kong Financial Reporting Standards, Hong Kong Accounting Standards and interpretations, herein collectively referred to as the new HKFRSs, which are generally effective for accounting periods beginning on or after January 1, 2005. The following new and revised HKFRSs affect the Group and are adopted for the first time for the current year's financial statements: HKAS 1 Presentation of Financial Statements HKAS 2 Inventories HKAS 7 Cash Flow Statements HKAS 8 Accounting Policies, Changes in Accounting Estimates and Errors HKAS 10 Events after the Balance Sheet Date HKAS 12 Income Taxes HKAS 14 Segment Reporting HKAS 16 Property, Plant and Equipment HKAS 17 Leases HKAS 18 Revenue HKAS 19 Employee Benefits HKAS 21 The Effects of Changes in Foreign Exchange Rates HKAS 23 Borrowing Costs HKAS 24 Related Party Disclosures HKAS 27 Consolidated and Separate Financial Statements HKAS 28 Investments in Associates HKAS 31 Interests in Joint Ventures HKAS 32 Financial Instruments: Disclosure and Presentation HKAS 33 Earnings per Share HKAS 36 Impairment of Assets HKAS 37 Provisions, Contingent Liabilities and Contingent Assets HKAS 38 Intangible Assets HKAS 39 Financial Instruments: Recognition and Measurement HKAS 39 Amendment Transition and Initial Recognition of Financial Assets and Financial Liabilities HKFRS 2 Share-based Payment HKFRS 3 Business Combinations The adoption of HKASs 1, 2, 7, 8, 10, 12, 14, 17, 18, 19, 21, 23, 24, 27, 28, 31, 33, 36, 37, 38 and HKFRS 3 has no material impact on the accounting policies of the Group and the methods of computation in the Group's financial statements. The impacts of adopting other HKFRSs are detailed as follows: (a) HKAS 16 - Property, Plant and Equipment In prior years, the Group's property, plant and equipment were classified into three categories: oil and gas properties, land and buildings (representing the onshore terminals for oil and gas processing), and vehicles and office equipment. Land and buildings were stated at valuation less accumulated depreciation. Depreciation for land and buildings is calculated on the straight-line basis at an annual rate estimated to write off the valuation of each asset over its expected useful life, ranging from 30 to 50 years. According to HKAS 16, property, plant and equipment are required to be categorised by major component and different useful lives, if any, should be applied in calculating the depreciation. F-13 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 2.2 IMPACT OF NEW AND REVISED HONG KONG FINANCIAL REPORTING STANDARDS ("HKFRSs")(CONT'D) (a) HKAS 16 - Property, Plant and Equipment (continued) Upon the adoption of HKAS 16, the Group has classified its property, plant and equipment into two categories: oil and gas properties and vehicles and office equipment. The Group has reclassified the onshore terminals previously classified as land and buildings to oil and gas properties as they will be used in similar operations and are expected to have similar economic useful lives. The Group has also decided to change its accounting policy to state the onshore terminals at cost instead of valuation and to amortise those terminals by the unit-of-production method on a property-by-property basis computed based on the total estimated units of proved developed reserves instead of the straight line method. Management believes the new policy will provide more relevant information and consistent accounting approach for oil and gas related assets. The effect of this change in accounting policy is to decrease both property, plant and equipment and the revaluation reserve as at January 1, 2005 and 2004 by RMB 274,671,000. No adjustment was made to the prior years' amounts as the impact on the prior years' consolidated income statements was not material. The effects of the above changes are summarized in note 2.4 to the financial statements. (b) HKASs 32 and 39 - Financial Instruments (i) Investments in equity and debt securities In prior periods, the Group classified its investments in short term debt and equity securities as short term investments which were not intended to be held on a continuing basis and those investments were stated at fair value at the balance sheet date, on an individual investment basis. The gains or losses arising from changes in the fair value of such securities were credited or charged to the income statement in the period in which they arose. Upon the adoption of HKAS 39, these securities held by the Group at January 1, 2005 in the amount of RMB 5,444,113,000 were designated as available-for-sale investments under the transitional provisions of HKAS 39 and accordingly are stated at fair value with gains or losses being recognised as a separate component of equity until subsequent derecognition or impairment. (ii) Convertible bonds In prior periods, convertible bonds were stated at amortised cost. Upon the adoption of HKAS 32 and HKAS 39, the Group's convertible bonds issued with a cash settlement option and other derivative features are split into liability and derivative components based on their fair values for measurement purposes. The effects of the above changes are summarised in note 2.4 to the financial statements. In accordance with HKAS 32, comparative amounts have been restated. F-14 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 2.2 IMPACT OF NEW AND REVISED HONG KONG FINANCIAL REPORTING STANDARDS ("HKFRSs")(CONT'D) (c) HKFRS 2 - Share-based Payment In prior periods, no recognition and measurement of share-based transactions in which employees (including directors) were granted share options over shares in the Company were required until such options were exercised by employees, at which time the share capital and share premium were credited with the proceeds received. Upon the adoption of HKFRS 2, when employees (including directors) render services as consideration for equity instruments ("equity-settled transactions"), the cost of equity-settled transactions with employees is measured by reference to the fair value at the date at which the instruments are granted. The main impact of HKFRS 2 on the Group is the recognition of the cost of these transactions and a corresponding entry to equity for employee share options. The revised accounting policy for share-based payment transactions is described in more detail in note 3 "Summary of significant Accounting Policies" below. The Group has adopted the provisions of HKFRS 2 retrospectively to all stock options granted from the date of its incorporation. The effects of adopting HKFRS 2 are summarized in note 2.4 to the financial statements. 2.3 IMPACT OF ISSUED BUT NOT YET EFFECTIVE HONG KONG FINANCIAL REPORTING STANDARDS The HKICPA has issued a number of new and revised HKFRSs that are not mandatory for these financial statements. The Group has not early applied these HKFRSs in these financial statements. The following new and revised HKFRSs, although not early adopted by the Group, will have impact on the Group's financial statements in the period of initial application. Unless otherwise stated, the following HKFRSs are effective for accounting periods beginning on or after January 1, 2006: HKAS 1 Amendment Capital Disclosures HKAS 21 Amendment The effects of Changes in Foreign Exchange Rate - Net Investment in a Foreign Operation HKAS 39 Amendment Cash Flow Hedge Accounting of Forecast Intragroup Transactions HKAS 39 Amendment The Fair Value Option HKFRSs 1 & 6 Amendments First-time Adoption of Hong Kong Financial Reporting Standards and Exploration for and Evaluation of Mineral Resources HKFRS 6 Exploration for and Evaluation of Mineral Resources HKFRS 7 Financial Instruments: Disclosures HK(IFRIC)-Int 4 Determining whether an Arrangement contains a Lease HK(IFRIC)-Int 5 Rights to Interests arising from Decommissioning, Restoration and Environmental Rehabilitation Funds The HKAS 1 Amendment shall be applied for accounting periods beginning on or after January 1, 2007. The revised standard will affect the disclosures about qualitative information about the Group's objective, policies and processes for managing capital; quantitative data about what the Company regards as capital; and compliance with any capital requirements and the consequences of any non-compliance. F-15 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 2.3 IMPACT OF ISSUED BUT NOT YET EFFECTIVE HONG KONG FINANCIAL REPORTING STANDARDS (CONT'D) HKFRS 6 deals with the accounting for exploration for and evaluation of mineral resources, including oil and gas. This HKFRS should be applied for accounting periods beginning on or after January 1, 2006. The Group expects that the adoption of HKFRS 6 will not have any significant impact on its results of operations and financial position. HKFRS 7 will replace HKAS 32 and has modified the disclosure requirements of HKAS 32 relating to financial instruments. This HKFRS shall be applied for accounting periods beginning on or after January 1, 2007. Except as stated above, the Group expects that the adoption of the other pronouncements listed above will not have any significant impact on the Group's financial statements in the period of initial application. 2.4 SUMMARY OF THE IMPACT OF CHANGES IN ACCOUNTING POLICIES (a) Effect on the consolidated balance sheet Effect of adopting --------------------------------------------- At January 1, 2005 HKAS 16# HKFRS 2# Effect of new policies Property, plant Recognition of Increase/(decrease) and equipment share-based payment Total RMB'000 RMB'000 RMB'000 Assets Property, plant and equipment, net (274,671) -- (274,671) ----------- Liabilities/equity Asset revaluation reserve (274,671) -- (274,671) Other reserves -- 110,144 110,144 Retained earnings -- (110,144) (110,144) ----------- (274,671) ----------- Effect of adopting ------------------------------------------------------------------- HKAS 16# HKASs 32 HKAS 39* HKFRS 2# At December 31, 2005 and 39* Change in Recognition of Effect of new policies Property, plant Convertible classification of share-based Increase/(decrease) and equipment bonds equity investments payment Total RMB'000 RMB'000 RMB'000 RMB'000 RMB'000 Assets Property, plant and equipment, net (274,671) -- -- -- (274,671) ------------ Liabilities/equity Long term guaranteed notes -- 373,060 -- -- 373,060 Asset revaluation reserve (274,671) -- -- -- (274,671) Other reserves -- -- 69,069 139,267 208,336 Retained earnings -- (373,060) (69,069) (139,267) (581,396) ------------ (274,671) ------------ F-16 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 2.4 SUMMARY OF THE IMPACT OF CHANGES IN ACCOUNTING POLICIES (CONT'D) (b) Effects on the balances of equity at January 1, 2003, 2004 and 2005 Effect of adopting --------------------------------------------- HKAS 16# HKFRS 2# Effect of new policies Property, plant Recognition of Increase/(decrease) and equipment share-based payment Total RMB'000 RMB'000 RMB'000 January 1, 2003 Asset revaluation reserve (274,671) -- (274,671) Other reserves -- 25,755 25,755 Retained earnings -- (25,755) (25,755) ------------ (274,671) ------------ January 1, 2004 Asset revaluation reserve (274,671) -- (274,671) Other reserves -- 63,502 63,502 Retained earnings -- (63,502) (63,502) (274,671) ------------ January 1, 2005 Asset revaluation reserve (274,671) -- (274,671) Other reserves -- 110,144 110,144 Retained earnings -- (110,144) (110,144) ------------ (274,671) ------------ * Adjustments taken effect prospectively from January 1, 2005. # Adjustments taken effect retrospectively.

F-17 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Subsidiaries A subsidiary is a company in which the Company, directly or indirectly, controls more than half of its voting power or issued share capital or controls the composition of its Board of Directors. The results of subsidiaries are included in the Company's income statement to the extent of dividends received and receivable. The Company's interests in subsidiaries are stated at cost less any impairment losses. Associates An associate is an entity, not being a subsidiary or a jointly-controlled entity, in which the Group has a long term interest of generally not less than 20% of the equity voting rights and over which it is in a position to exercise significant influence. The Group's share of the post-acquisition results and reserves of the associates are included in the consolidated income statement and consolidated reserves, respectively. The Group's proportionate interests in the associates are stated in the consolidated balance sheet at the Group's share of net assets under the equity method of accounting, less any impairment losses. Joint Ventures Certain of the group's activities are conducted through joint arrangements, including the production sharing arrangements detailed in note 5 below. These arrangements are a form of joint venture whereby a contractual arrangement exists between two or more parties to undertake an economic activity that is subject to joint control. These joint arrangements are included in the consolidated financial statements in proportion to the group's interests in the income, expenses, assets and liabilities of these arrangements. Related parties A party is considered to be related to the Group if: (a) the party directly or indirectly through one or more intermediaries, (i) controls, is controlled by, or is under common control with, the Group ; (ii) has an interest in the Group that gives it significant influence over the Group; or (iii) has joint control over the Group; (b) the party is an associate; (c) the party is a jointly controlled entity; (d) the party is a member of the key management personnel of the Group or its parent; (e) the party is a close member of the family of any individual referred to in (a) or (d); or (f) the party is an entity that is controlled, jointly controlled or significantly influenced by or for which significant voting power in such entity resides with, directly or indirectly, any individual referred to in (d) or (e). F-18 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Impairment of assets Where an indication of impairment exists, or when annual impairment testing for an asset (other than inventories and financial assets) is required, the asset's recoverable amount is estimated. An asset's recoverable amount is calculated as the higher of the asset's or cash-generating unit's value in use and its fair value less costs to sell, and is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets, in which case, the recoverable amount is determined for the cash-generating unit to which the asset belongs. An impairment loss is recognised only if the carrying amount of an asset exceeds its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. An impairment loss is charged to the income statement in the period in which it arises. An assessment is made at each reporting date as to whether there is any indication that previously recognised impairment losses may no longer exist or may have decreased. If such indication exists, the recoverable amount is estimated. A previously recognised impairment loss is reversed only if there has been a change in the estimates used to determine the recoverable amount of an asset, however not to an amount higher than the carrying amount that would have been determined (net of any depreciation/amortisation), had no impairment loss been recognised for the asset in prior years. A reversal of an impairment loss is credited to the income statement in the period in which it arises, unless the asset is carried at a revalued amount, in which case the reversal of the impairment loss is accounted for in accordance with the relevant accounting policy for that revalued asset. F-19 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Property, plant and equipment Property, plant and equipment comprise oil and gas properties, and vehicles and office equipment. (i) Oil and gas properties For oil and gas properties, the successful efforts method of accounting is adopted. The Group capitalises initial acquisition costs of oil and gas properties. Impairment of initial acquisition costs is recognised based on exploratory experience and management judgment. Upon discovery of commercial reserves, acquisition costs are transferred to proved properties. The costs of drilling and equipping successful exploratory wells, all development expenditures on construction, installation or completion of infrastructure facilities such as platforms, pipelines, processing plants and the drilling of development wells, including those renewals and betterments which extend the economic lives of the assets, and the borrowing costs arising from borrowings used to finance the development of oil and gas properties before they are substantially ready for production are capitalised. The costs of unsuccessful exploratory wells and all other exploration costs are expensed as incurred. Exploratory wells are evaluated for economic viability within one year of completion. Exploratory wells that discover potentially economic reserves in areas where major capital expenditure will be required before production would begin and when the major capital expenditure depends upon successful completion of further exploratory work remain capitalised and are reviewed periodically for impairment. Productive oil and gas properties and other tangible and intangible costs of producing properties are amortised using the unit-of-production method on a property-by-property basis under which the ratio of produced oil and gas to the estimated remaining proved developed reserves is used to determine the depreciation, depletion and amortisation provision. Costs associated with significant development projects are not depleted until commercial production commences and the reserves related to those costs are excluded from the calculation of depletion. Capitalised acquisition costs of proved properties are amortised by the unit-of-production method on a property-by-property basis computed according to the total estimated units of proved reserves. The Group estimates future dismantlement costs for oil and gas properties with reference to the estimates provided from either internal or external engineers after taking into consideration the anticipated method of dismantlement required in accordance with current legislation and industry practices. The associated cost is capitalised and the liability is discounted and an accretion expense is recognised using the credit-adjusted risk-free interest rate in effect when the liability is initially recognised. No market-risk premium has been included in the Company's calculation of asset retirement obligations balances since no reliable estimate can be made by the Company. F-20 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Property, plant and equipment (cont'd) (ii) Vehicles and office equipment Vehicles and office equipment are stated at cost less accumulated depreciation and impairment losses. The straight-line method is adopted to depreciate the cost less any estimated residual value of these assets over their expected useful lives. The Group estimates the useful lives of vehicles and office equipment to be five years. Where parts of an item of property, plant and equipment have different useful lives, the cost of that item is allocated on a recoverable basis among the parts and each part is depreciated separately. Residual values, useful lives and the depreciation method are reviewed and, adjusted if appropriate, at each balance sheet date. An item of property, plant and equipment is derecognised upon disposal or where no future economic benefits are expected from its use or disposal. Any gain or loss on disposal or retirement recognised in the income statement in the year that the asset is derecognised is the difference between the net sales proceeds and the carrying value of the relevant asset. Intangible assets The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets with finite lives are amortised over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortisation period and the amortisation method for an intangible asset with a finite useful life are reviewed as least at each balance sheet date. Research and development costs All research costs are charged to the income statement as incurred. Expenditure (other than relating to oil and gas properties discussed above) incurred on projects to develop new products is capitalised and deferred only when the Group can demonstrate the technical feasibility of completing the intangible asset so that it will be available for use or sale, its intention to complete and its ability to use or sell the asset, how the asset will generate future economic benefits, the availability of resources to complete the project and the ability to measure reliably the expenditure during the development. Product development expenditure which does not meet these criteria is expensed when incurred. No development costs were capitalised during the year.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Investments and other financial assets Applicable to the year ended December 31, 2004: Short term investment Short term investments are investments in debt and equity securities not intended to be held on a continuing basis and are stated at their fair values on the basis of their quoted market prices at the balance sheet date, on an individual investment basis. The gains or losses arising from changes in the fair value of a security are credited or charged to the income statement in the period in which they arise. Applicable to the year ended December 31, 2005: Financial assets in the scope of HKAS 39 are classified as financial assets at fair value through profit or loss, loans and receivables, held-to-maturity investments, and available-for-sale financial assets, as appropriate. When financial assets are recognised initially, they are measured at fair value, plus, in the case of investments not at fair value through profit or loss, directly attributable transaction costs. The Group determines the classification of its financial assets after initial recognition and, where allowed and appropriate, re-evaluates this designation at the balance sheet date. All regular way purchases and sales of financial assets are recognised on the trade date i.e., the date that the Group commits to purchase the asset. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the period generally established by regulation or convention in the marketplace. (a) Financial assets at fair value through profit or loss Financial assets classified as held for trading are included in the category "financial assets at fair value through profit or loss". Financial assets are classified as held for trading if they are acquired for the purpose of selling in the near term. Derivatives are also classified as held for trading unless they are designated and effective hedging instruments. Gains or losses on investments held for trading are recognised in the income statement. (b) Loans and receivables Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They arise when the Group provides money, goods or services directly to a debtor with no intention of trading the receivable. They are included in current assets, except for those with maturities greater than 12 months after the balance sheet date, which are included in non-current assets. Loans and receivables are included in trade and other receivables in the balance sheet. (c) Held-to-maturity investments During this year, the Group did not hold any investments assets in this category. F-22 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Investments and other financial assets (continued) (d) Available-for-sale financial assets Available-for-sale financial assets are those non-derivative financial assets in listed and unlisted equity securities that are designated as available-for-sale or are not classified in any of the other categories. After initial recognition available-for-sale financial assets are measured at fair value with gains or losses being recognised as a separate component of equity until the investment is derecognised or until the investment is determined to be impaired at which time the cumulative gain or loss previously reported in equity is included in the income statement. When the fair value of unlisted equity securities can not be reliably measured because (a) the variability in the range of reasonable fair value estimates is significant or that investment or (b) the probabilities of the various estimates within the range cannot be reasonably assessed and used in estimating fair value, such securities are stated at cost less any impairment losses. Fair Value The fair value of investments that are actively traded in organised financial markets is determined by reference to quoted market bid price at the close of business at the balance sheet date. For investments where there is no active market, fair value is determined using valuation techniques. Such techniques include using recent arm's length market transactions; reference to the current market value of another instrument which is substantially the same; a discounted cash flow analysis; and option pricing models. Impairment of financial assets (Applicable to the year ended December 31, 2005) The Group assesses at each balance sheet date whether there is any objective evidence that a financial asset or group of financial assets is impaired. Assets carried at amortised cost If there is objective evidence that an impairment loss on loans and receivables carried at amortised cost has been incurred, the amount of the loss is measured as the difference between the asset's carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset's original effective interest rate (i.e., the effective interest rate computed at initial recognition). The carrying amount of the asset is reduced either directly or through the use of an allowance account. The amount of the impairment loss is recognised in profit or loss. The Group first assesses whether objective evidence of impairment exists individually for financial assets that are individually significant, and individually or collectively for financial assets that are not individually significant. If it is determined that no objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, the asset is included in a group of financial assets with similar credit risk characteristics and that group is collectively assessed for impairment. Assets that are individually assessed for impairment and for which an impairment loss is or continues to be recognised are not included in a collective assessment of impairment. F-23 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Impairment of financial assets (Applicable to the year ended December 31, 2005) (continued) If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognised, the previously recognised impairment loss is reversed. Any subsequent reversal of an impairment loss is recognised in the income statement, to the extent that the carrying value of the asset does not exceed its amortised cost at the reversal date. Available-for-sale financial assets If an available-for-sale asset is impaired, an amount comprising the difference between its cost (net of any principal payment and amortisation) and its current fair value, less any impairment loss previously recognised in profit or loss, is transferred from equity to the income statement. Impairment losses on equity instruments classified as available-for-sale are not reversed through profit or loss. Derecognition of financial assets (applicable to the year ended December 31, 2005) A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognised where: o the rights to receive cash flows from the asset have expired; o the Group retains the rights to receive cash flows from the asset, but has assumed an obligation to pay in full without material delay to a third party under a "pass-through" arrangement; or o the Group has transferred its rights to receive cash flows from the asset and either (a) has transferred substantially all the risks and rewards of the asset, or (b) has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset. Where the Group has transferred its rights to receive cash flows from an asset and has neither transferred nor retained substantially all the risks and rewards of the asset nor transferred control of the asset, the asset is recognised to the extent of the Group's continuing involvement in the asset. Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay. Where continuing involvement takes the form of a written and/or purchased option (including a cash settled option or similar provision) on the transferred asset, the extent of the Group's continuing involvement is the amount of the transferred asset that the Group may repurchase, except that in the case of a written put option (including a cash-settled option or similar provision) on an asset measured at fair value, where the extent of the Group's continuing involvement is limited to the lower of the fair value of the transferred asset and the option exercise price. F-24 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Interest-bearing loans and borrowings All loans and borrowings are initially recognised at the fair value of the consideration received less directly attributable transaction costs. After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortised cost using the effective interest method. Gains and losses are recognised in net profit or loss when the liabilities are derecognised as well as through the amortisation process. Convertible bonds The Group's convertible bonds issued with a cash settlement option and other embedded derivative features are split into liability and derivative components according to their fair values for measurement purposes. The fair value of the liability component is determined using the market rate for an equivalent non-convertible bond on the issuance of convertible bonds and this amount is carried as a long term liability on the amortised cost basis until extinguished on conversion or redemption. The derivative component is remeasured at each balance sheet date and any gains or losses arising from change in the fair value are recognised in the income statement. Both the liability and the related embedded derivative components are presented together for financial statements reporting purposes. Derecognition of financial liabilities (applicable to the year ended December 31, 2005) A financial liability is derecognised when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and a recognition of a new liability, and the difference between the respective carrying amounts is recognised in profit or loss. Derivative financial instruments (applicable to the year ended December 31, 2005) The Group uses currency swaps to hedge its risks associated with currency exchange fluctuations. Such derivative financial instruments are initially recognised at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative. Any gains or losses arising from changes in fair value on derivatives that do not qualify for hedge accounting are taken directly to net profit or loss for the year. The fair value of currency swap contracts is determined by reference to market values for similar instruments. F-25 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Inventories and supplies Inventories consist primarily of oil and supplies consist mainly of items for repairs and maintenance of oil and gas properties. Inventories are stated at the lower of cost and net realisable value. Costs of inventories and supplies represent purchase or production cost of goods and are determined on a weighted average basis. Net realisable value is based on estimated selling prices less any estimated costs to be incurred to completion and disposal. Supplies are capitalised to property, plant and equipment when used for renewals and betterments of oil and gas properties and have resulted in an increase in the future economic values of oil and gas properties or are recognised as expenses when used. Cash and cash equivalents For the purpose of the consolidated cash flow statement, cash and cash equivalents comprise cash on hand and demand deposits, and short term highly liquid investments which are readily convertible into known amounts of cash and which are subject to an insignificant risk of changes in value, and have a short maturity of generally within three months when acquired, less bank overdrafts which are payable on demand and form an integral part of the Group's cash management. For the purpose of the balance sheet, cash and cash equivalents comprise cash on hand and at banks, and term deposits with maturities of three months or less which are not restricted to use. Provisions A provision is recognised when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation, provided that a reliable estimate can be made of the amount of the obligation. When the effect of discounting is material, the amount recognised for a provision is the present value at the balance sheet date of the future expenditures expected to be required to settle the obligation. The increase in the discounted present value amount arising from the passage of time is included in finance costs in the income statement. Provisions for dismantlement are made based on the present value of the future costs expected to be incurred, on a property-by-property basis, in respect of the Group's expected dismantlement and abandonment costs at the end of the related oil exploration and recovery activities. F-26 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Income tax Income tax comprises current and deferred tax. Income tax is recognised in the income statement or in equity if it relates to items that are recognised in the same or a different period directly in equity. Current tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. Deferred tax is provided, using the liability method, on all temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. Deferred tax liabilities are recognised for all taxable temporary differences: o Except where the deferred tax liability arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and o in respect of taxable temporary differences associated with investments in subsidiaries and associates, except where the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future. o Deferred tax assets are recognised for all deductible temporary differences, carry forward of unused tax credits and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised, except where the deferred tax asset relating to the deductible temporary differences arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and o in respect of deductible temporary differences associated with investments in subsidiaries and associates, deferred tax assets are only recognised to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilised. The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised. Conversely, previously unrecognised deferred tax assets are reassessed at each balance sheet date and are recognised to the extent that it is probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantially enacted at the balance sheet date. Deferred tax assets and deferred tax liabilities are offset, if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority. F-27 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Revenue recognition Revenue is recognised when it is probable that the economic benefits will flow to the Group and when the revenue can be measured reliably, on the following bases: (i) Oil and gas sales Oil and gas sales represent the invoiced value of sales of oil and gas attributable to the interests of the Group, net of royalties and PRC government share oil that are lifted and sold on behalf of the PRC government. Sales are recognised when the significant risks and rewards of ownership of oil and gas have been transferred to customers. Oil and gas lifted and sold by the Group above or below the Group's participating interests in the production sharing contracts result in overlifts and underlifts. The Group records these transactions in accordance with the entitlement method under which overlifts are recorded as liabilities and underlifts are recorded as assets at year end oil prices. Settlement will be in kind when the liftings are equalised or in cash when production ceases. The Group has entered into gas sales contracts with customers which contain take-or-pay clauses. The clauses require those customers to take a specified minimum volume of gas each year. If the minimum volume of gas is not taken, those customers must pay for the deficiency gas, even though the gas is not taken. Those customers can offset the deficiency payment against any future purchases in excess of the specified volume. The Group records any deficiency payments as deferred revenue which is included in other payables until any make-up gas is taken by those customers or the expiry of the contracts. (ii) Marketing revenues Marketing revenues represent sales of oil purchased from the foreign partner under the production sharing contracts and revenues from the trading of oil through the Company's subsidiary in Singapore. The title, together with the risks and rewards of the ownership of such oil purchased from the foreign partners, is transferred to the Group from the foreign partners and other unrelated oil and gas companies before the Group sells such oil to its customers. The cost of the oil sold is included in crude oil and product purchases. (iii) Other income Other income mainly represents project management fees charged to the foreign partners and handling fees charged to customers and is recognised when the services are rendered. (iv) Dividend income Dividend income is recognised when the shareholders' right to receive payment has been established. (v) Interest income Interest income from deposits placed with banks and other financial instruments is recognised on a time proportion basis taking into account the effective yield on the assets. F-28 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Employee benefits Share-based payment transactions The Company has adopted share option schemes for the purpose of providing incentives and rewards to eligible participants who contribute to the success of the Group's operations. Employees (including directors) of the Group will from time to time receive remuneration in the form of share-based payment transactions, whereby employees render services as consideration for equity instruments ("equity-settled transactions"). The cost of equity-settled transactions with employees is measured by reference to the fair value at the date at which they are granted. The fair value is determined by using a Black-Scholes model, further details of which are given in note 31. In valuing equity-settled transactions, no account is taken of any performance conditions, other than conditions linked to the price of the shares of the Company, if applicable. The cost of equity-settled transactions is recognised, together with a corresponding increase in equity, over the period in which the performance and/or service conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award (the "vesting date"). The cumulative expenses recognised for equity-settled transactions at each balance sheet date until the vesting date reflects the extent to which the vesting period has expired and the Group's best estimate of the number of equity instruments that will ultimately vest. The charge or credit to the income statement for a period represents the movement in cumulative expense recognised as at the beginning and end of that period. No expense is recognised for awards that do not ultimately vest, except for awards where vesting is conditional upon a market condition, which are treated as vesting irrespective of whether or not the market condition is satisfied, provided that all other performance conditions are satisfied. Where the terms of an equity-settled award are modified, as a minimum, an expense is recognised as if the terms had not been modified. In addition, an expense is recognised for any modification, which increases the total fair value of the share-based payment arrangement, or is otherwise beneficial to the employee as measured at the date of modification. Where an equity-settled award is cancelled, it is treated as if it had vested on the date of cancellation, and any expenses not yet recognised for the award is recognised immediately. However, if a new award is substituted for the cancelled award, and is designated as a replacement award on the date that it is granted, the cancelled and new awards are treated as if they were a modification of the original award, as described in the previous paragraph. The Group has adopted the provisions of HKFRS 2 retrospectively to all stock options granted from the date of its incorporation. The dilutive effect of outstanding options is reflected as additional share dilution in the computation of earnings per share. F-29 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Retirement and termination benefits The Group participates in defined contribution plans in accordance with local laws and regulations for full-time employees in the PRC and other countries in which it operates. The plans provide for contributions ranging from 5% to 22% of the employees' basic salaries. The Group's contributions to these defined contribution plans are charged to expense in the year to which they relate. Dividends Final and special final dividends proposed by the directors are classified as a separate allocation of retained earnings within the equity section of the balance sheet, until they have been approved by the shareholders in a general meeting. When these dividends have been approved by the shareholders and declared, they are recognised as a liability. Interim and special interim dividends are simultaneously proposed and declared, because the Company's memorandum and articles of association grant the directors the authority to declare interim dividends. Consequently, interim dividends are recognised immediately as a liability when they are proposed and declared. Borrowing costs Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, i.e. assets that necessarily take a substantial period of time to get ready for their intended use or sale, are capitalised as part of the cost of those assets. The capitalisation of such borrowing costs ceases when the assets are substantially ready for their intended use or sale. To the extent that funds are borrowed specifically for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalisation on that asset is determined as the actual borrowing costs incurred on that borrowing during the period less any investment income on the temporary investment of those borrowings. To the extent that funds are borrowed generally and used for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalisation is determined by applying a capitalisation rate to the expenditures on that asset. The capitalisation rate is the weighted average of the borrowing costs applicable to the borrowings of the group that are outstanding during the period, other than borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs capitalised incurred during a period should not exceed the amount of borrowing cost incurred during that period. Borrowing costs include interest charges and other costs incurred in connection with the borrowing of funds, including amortisation of discounts or premiums relating to the borrowing, and amortisation of ancillary costs incurred in connection with arranging the borrowing. F-30 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Foreign currencies These financial statements are presented in RMB. Each entity in the Group maintains its books and records in its own functional currency. Foreign currency transactions are initially recorded using the functional currency rates ruling at the date of transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the functional currency rates of exchange ruling at the balance sheet date. Exchange differences are dealt with in the income statement. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. On consolidation, the balance sheet of the Company and the overseas subsidiaries, other than the subsidiaries in the PRC, are translated into RMB at the exchange rates ruling at the balance sheet date and, their income statements are translated into RMB at the weighted average exchange rates for the year. The resulting translation differences are included in the cumulative translation reserve. For the purpose of the consolidated cash flow statement, the cash flows of overseas subsidiaries are translated into RMB at the exchange rates ruling at the dates of the cash flows. Frequently recurring cash flows of overseas subsidiaries which arise throughout the year are translated into RMB at the weighted average exchange rates for the year. Repairs, maintenance and overhaul costs Repairs, maintenance and overhaul costs are normally charged to the income statement as operating expenses in the period in which they are incurred. Operating leases Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating leases. Where the Company is the lessee, rentals payable under the operating leases are charged to the income statement on the straight-line basis over the lease terms. Contingencies Contingent liabilities are not recognised in the financial statements. They are disclosed unless the possibility of an outflow of resources embodying economic benefits is remote. A contingent asset is not recognised in the financial statements, but are disclosed when an inflow of economic benefits is probable.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D) Subsequent events Post-year-end events that provide additional information about the Company's position at the balance sheet date or those that indicate the going concern assumption is not appropriate (adjusting events) are reflected in the financial statements. Post-year-end events that are not adjusting events are disclosed in the notes when material. Use of estimates The preparation of financial statements in conformity with Hong Kong GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The most significant estimates pertain to proved oil and gas reserve volumes and the future development, purchase price allocation, provision for dismantlement and impairment as well as estimates relating to certain oil and gas revenues and expenses. Actual amounts could differ from those estimates and assumptions. More details are given in notes 3, 16 and 28. F-32 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 4. ACQUISITIONS During the year, the Group completed the acquisition of the North West Shelf Project ("NWS Project"), including an interest of approximately 5.3% in the NWS Project and a 25% interest in the China LNG Joint Venture, a new joint venture established within the NWS Project. The Group acquired the NWS Project to expand its upstream oil and gas reserves and production. The Group's participation in the NWS Project has not started commercial operations. Details of the net assets acquired are as follows: Purchase consideration: RMB'000 ------------- Consideration paid 4,341,783 Direct costs relating to the acquisition 87,522 -------------- Total purchase consideration 4,429,305 -------------- The assets and liabilities arising from the acquisition are as follows: RMB'000 -------------- Oil and gas properties 3,129,662 Intangible assets - gas processing rights 1,299,643 -------------- Net assets acquired 4,429,305 -------------- Purchase consideration settled in cash 4,429,305 -------------- The purchase price allocation set out above is still preliminary, pending the confirmation of the tax basis of the underlying assets. The interest of the Group in the NWS Project has been charged to the other partners of the Project as security for certain of the Group's liabilities relating to the Project. In addition, the Company, through its wholly-owned subsidiary, has signed an agreement with a Canadian based company, MEG Energy Corporation ("MEG"), to acquire a 16.69% equity interest in MEG. The Company completed the transaction and paid C$150 million (equivalent of RMB1,017 million) for the acquisition of 13,636,364 common shares of MEG in March 2005. MEG is principally engaged in the exploitation and production of oil sands. The investment in the unlisted shares of this company is accounted for as a non-current available-for-sales asset and is stated at cost less any impairment. F-33 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 5. PRODUCTION SHARING CONTRACTS PRC For production sharing contracts in the PRC, the foreign parties to the contracts ("foreign partners") are normally required to bear all exploration costs during the exploration period and such exploration costs can be recovered according to the production sharing formula after commercial discoveries are made and production begins. After the initial exploration stage, the development and operating costs are funded by the Group and the foreign partners according to their respective participating interests. In general, the Group has the option to take up to 51% participating interest in a production sharing contract and may exercise such option after the foreign partners have independently undertaken all the exploration risks and costs and made viable commercial discoveries. After the Group exercises its option to take a participating interest in a production sharing contract, the Group accounts for the oil and gas properties using the proportional method under which the Group recognises its share of development costs, revenues and expenses from such operations according to its participating interest in the production sharing contract. The Group does not account for either the exploration costs incurred by its foreign partners or the foreign partners' share of development costs and revenues and expenses from such operations. Part of the annual gross production of oil and gas in the PRC is distributed to the PRC government as settlement of royalties which are payable pursuant to a sliding scale. The Group and the foreign partners also pay the value-added tax to the tax bureau at a pre-determined rate. In addition, there is a pre-agreed portion of oil and gas designated to recover all exploration costs, development costs, operating costs incurred and related interest according to the participating interests between the Group and the foreign partners. Any remaining oil after the foregoing priority allocations is first distributed to the PRC government as government share oil on a pre-determined ratio pursuant to a sliding scale, and then distributed to the Group and the foreign partners according to their respective participating interests. As the government share is not included in the Group's interest in the annual production, the net sales of the Group do not include the sales revenue of the government share oil. The foreign partners have the right either to take possession of their allocable remainder oil for sale in the international market, or to negotiate with the Group to sell their allocable remainder oil to the Group for sale in the PRC market. Overseas The Group and the other partners to the overseas production sharing contracts are required to bear all exploration, development and operating costs according to their respective participating interests. Exploration, development and operating costs which qualify for recovery can be recovered according to the production sharing formula after commercial discoveries are made and production begins. The Group's net interest in the production sharing contracts in overseas consists of its participating interest in the properties covered under the relevant production sharing contracts, less oil and gas distributed to the local government and the domestic market obligation. F-34 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 6. SEGMENT INFORMATION Segment information is presented by way of two segment formats: (i) on a primary segment reporting basis, by business segment; and (ii) on a secondary segment reporting basis, by geographical segment. Intersegment transactions: segment revenue, segment expenses and segment performance include transfers between business segments and between geographical segments. Such transfers are accounted for at cost. Those transfers are eliminated on consolidation. (a) Business segments The Group is organised on a worldwide basis into three major operating segments. The Group is involved in the upstream operating activities of the petroleum industry that comprise independent operations, production sharing contracts with foreign partners and trading business. These segments are determined primarily because the senior management makes key operating decisions and assesses performance of the segments separately. The Group evaluates the performance of each segment based on profit or loss from operations before income taxes.

EARNINGS PER SHARE (CONT'D) Net income per ADS for the three years ended December 31, 2005 has been computed by dividing net income by the number of ADS outstanding. Each ADS represented 100 shares. The calculation of basic earnings per share amounts is based on the net profit for the year and the weighted average number of ordinary shares in issue during the year. The calculation of diluted earnings per share amounts is based on the net profit for the year, adjusted to reflect the interest expense and losses recognised on the derivative component of the convertible bonds. The weighted average number of ordinary shares used in the calculation is the ordinary shares in issue during the year, as used in the basic earnings per share calculation, and the weighted average number of ordinary shares assumed to have been issued at no consideration on the deemed exercise or conversion of all the dilutive potential ordinary shares into ordinary shares.

F-62 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 29. SHARE CAPITAL (CONT'D) Share option schemes (cont'd) The fair value of the share options granted during the year was HK$103,811,616. The fair value of equity-settled share options granted during the year was estimated as at the date of grant, using the Black-Scholes model, taking into account the terms and conditions upon which the options were granted. The following table lists the assumptions to the model used for the year ended December 31, 2005: Dividend yield 2% Expected volatility 31% Risk-free interest rate 4.57% Expected life of option 5 years Weighted average share price HK$5.62 The expected life of the options is based on the historical data and is not necessarily indicative of the exercise patterns that may occur. The expected volatility reflects the assumption that the historical volatility is indicative of future trends, which may also not necessarily be the actual outcome. No other feature of the options granted was incorporated into the measurement of fair value. Any changes to the above assumptions may affect the estimation of the fair value of the option. 2,300,100 share options granted under the 2002 Share Option Scheme and the 2001 Share Option Scheme have been exercised since the respective dates of grant and up to the date when the Board of Directors approved the financial statements. On April 1, 2005, Mr. Erwin Schurtengberger surrendered 1,150,000 share options following his resignation as an independent non-executive director of the Company. The weighted average closing price of the shares immediately on the day before the exercise of the options was HK$4.04. The share options exercised during the year resulted in the issue of 2,300,100 ordinary shares of the Company and new share capital of RMB49,000 and share premium of RMB4,451,000. The total number of options exercisable as of December 31, 2005 was 70,416,522. No share options had been cancelled during the year ended December 31, 2005. At the balance sheet date, the Company had 169,063,300 share options outstanding under these share options schemes which represented approximately 0.4% of the Company's shares in issues as at that date. The exercise in full of the remaining share options would, under the present capital structure of the Company, result in the issue of 169,063,300 additional ordinary shares of the Company and additional share capital of RMB3,517,531 and share premium of RMB602,823,748.

CONTINGENT LIABILITIES As of December 2005 and 2004, there were no material contingent liabilities not provided for in the financial statements. F-66 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 34. COMMITMENTS (i) Capital commitments As at December 31, 2005, the Group and the Company had the following capital commitments, principally for the construction and purchase of property, plant and equipment: 2004 2005 ----------- ----------- RMB'000 RMB'000 Contracted for 9,568,971 7,511,100 Authorised, but not contracted for 20,331,504 23,736,582 As at December 31, 2005, the Group had unutilised banking facilities amounting, to approximately RMB33,450,791,000 (2004: RMB20,662,120,000). (ii) Operating lease commitments (a) Office properties The Group leases certain of its office properties under operating lease arrangements, leases properties are negotiated for terms ranging from 10 months to 3 years. As at December 31, 2005, the Group had total minimum lease payments under non-cancelable operating leases falling due as follows: 2004 2005 ------------ ------------ RMB'000 RMB'000 Commitments due: - Within one year 24,824 157,181 - After one year but within two years 549 22,351 - After two year but within five years -- 23,972 ------------ ------------ 25,373 203,504 ============ ============ (b) Plant and equipment The Group leases certain of its plant and equipment under operating lease arrangements for a term of 10 years.

COMMITMENTS (CONT'D) (iii) Financial instruments (a) Currency swap contracts As at December 31, 2005, the Group had a currency swap contract with a financial institution to sell United States dollars in exchange for Japanese Yen in order to hedge against future repayments of certain Japanese Yen denominated loans. The hedged Japanese Yen loans bore interest at a fixed rate of 4.5% per annum. The interest stipulated in the swap contract for the United States dollars was the floating LIBOR rate. The details are as follows: 2004 2005 ------------------------------ -------------------------- Weighted Weighted Notional average Notional average contract contractual contract contractual amount exchange rate amount exchange rate (JPY'000) (JPY/US$) (JPY'000) (JPY/US$) Year 2005 271,470 95.00 -- -- 2006 271,470 95.00 271,470 95.00 2007 271,470 95.00 271,470 95.00 (b) Fair value of financial instruments The carrying value of cash and cash equivalents, time deposits, available-for-sale investments, accounts receivables, other current assets, accounts payable and other payables approximated to fair value due to the short maturity of these instruments. The estimated fair value of long term bank loans based on current market interest rates was approximately RMB868,886,000 as at December 31, 2005 (2004: RMB967,770,000). The estimated fair value of long term guaranteed notes based on current market interest rates was approximately RMB 16,592,412,000 as at December 31, 2005 (2004: RMB16,428,934,000). F-68 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 35. CONCENTRATION OF RISKS (a) Credit risk The carrying amount of cash and cash equivalents, time deposits, liquidity funds and bond investments, accounts receivable and other receivables, and due from related parties and other current assets except for prepayments represents our maximum exposure to credit risk in relation to financial assets. The majority of the Group's accounts receivable is related to sales of oil and natural gas to third party customers. The Group performs ongoing credit evaluations of the customers' financial condition and generally do not require collateral on accounts receivable. The Group maintains a provision for doubtful accounts and actual losses have been within management's expectation. No other financial assets carry a significant exposure to credit risk. (b) Currency risk Substantially all of the Group's oil and gas sales are denominated in Renminbi and US dollars. In the past decade, the PRC government's policy of maintaining a stable exchange rate and China's ample foreign reserves has contributed to the stability of the Renminbi. Starting from July 21, 2005, China reformed the exchange rate regime by moving into a managed floating exchange rate regime based on market supply and demand with reference to a basket of currencies. Renminbi would no longer be pegged to the US dollar. From that day to December 31, 2005, Renminbi has appreciated by approximately 2.5% against US dollars. The appreciation of Renminbi against US dollars may have the following impact on the Group. On one hand, since the benchmark oil and gas prices are usually in US dollars, the Group's oil and gas sales may decrease due to the depreciation of US dollars against Renminbi. On the other hand, the depreciation of US dollars against Renminbi will also decrease the Group's costs for imported equipment and materials, most of which are denominated in US dollars. In addition, the debt repayment by the Group will decrease since more than 99% of the Group's debts are also denominated in U.S. dollars. As of the end of 2005, the balance of the yen-denominated loans was only RMB37,307,000. Since the Group has hedged the yen loans against foreign currency swaps, the Group does not expect any exchange risk relating to Japanese yen in the future. (c) Interest rate risk As of the end of 2005, the interest rates for all balance of our debts were fixed. The term of the weighted average balance was approximately 8 years. The average interest rate payable by the Group is favorable under the environment of interest rate hike. (d) Business risk The major operations are conducted in the PRC, Indonesia and Australia and accordingly are subject to special considerations and significant risks not typically associated with investments in equity securities of the United States of America and Western European companies. These include risks associated with, among others, the oil and gas industry, the political, economic and legal environments, influence of the national authorities over price setting and competition in the industry. F-69 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 35. CONCENTRATION OF RISKS (CONT'D) (e) Concentration of customers A substantial portion of the oil and gas sales of the Group is made to a small number of customers on an open account basis. Details of the sales to these customers are as follows: 2003 2004 2005 ------------ ----------- ----------- RMB'000 RMB'000 RMB'000 China Petroleum & Chemical Corporation 6,975,069 10,634,066 15,625,736 PetroChina Company Limited 1,446,169 1,944,709 1,776,199 Castle Peak Power Company Limited 841,285 1,070,436 1,107,314 36. ADDITIONAL FINANCIAL INFORMATION As at December 31, 2005, net current assets and total assets less current liabilities of the Group amounted to approximately RMB30,805,199,000 and RMB101,148,848,000 (2004: RMB24,890,362,000 and RMB83,399,497,000 (restated)), respectively. 37. SUBSEQUENT EVENT On January 8, 2006, the Company signed a definitive agreement with South Atlantic Petroleum Limited ("SAPETRO") to acquire a 45% working interest in an offshore oil mining license 130 "OML 130" in Nigeria for a cash consideration of US$2.268 billion, subject to adjustment. Conditional on, among other things, the approval of the Nigerian National Petroleum Corporation ("NNPC") and the PRC government, the transaction is expected to be completed in the first half of 2006. On January 27, 2006, CNOOC Africa Limited, a wholly-owned subsidiary of the Company, signed an agreement to acquire from AERD Projects Nigeria Limited a 35% of right to Oil Prospecting Licence 229 "OPL229" in Nigeria for US$ 60 million in cash, subject to adjustments. 38. SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (a) Net profit and net equity (i) Short term investments In 2003, according to Hong Kong GAAP, available-for-sale investments in marketable securities were measured at fair value and related unrealised holding gains and losses are included in the current period's earnings. According to US GAAP, such investments are also measured at fair value and classified in accordance with Statement of Financial Accounting Standards ("SFAS") No.115. Under US GAAP, related unrealised gains and losses on available-for-sale securities were excluded from the current period's earnings and included in other comprehensive income. F-70 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 38. SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONT'D) (a) Net profit and net equity (continued) (ii) Impairment of long-lived assets Under Hong Kong GAAP, impairment charges are recognised when a long-lived asset's carrying amount exceeds the higher of an asset's fair value less costs to sell and value in use, which incorporates discounting the asset's estimated future cash flows. Under US GAAP, long-lived assets are assessed for possible impairment in accordance with SFAS No.144, "Accounting for the impairment or disposal of long-lived assets". SFAS No. 144 requires the Group to (a) recognise an impairment loss only if the carrying amount of a long-lived asset is not recoverable from its undiscounted cash flows and (b) measure an impairment loss as the difference between the carrying amount and fair value of the asset. SFAS No. 144 requires that a long-lived asset to be abandoned, exchanged for a similar productive asset, or distributed to owners in a spin-off be considered as held and used until it is disposed of. SFAS No. 144 also requires the Group to assess the need for an impairment of capitalised costs of proved oil and gas properties and the costs of wells and related equipment and facilities on a property-by-property basis. If an impairment is indicated based on undiscounted expected future cash flows, then an impairment is recognised to the extent that net capitalised costs exceed the estimated fair value of the property. Fair value of the property is estimated by the Group using the present value of future cash flows. The impairment was determined based on the difference between the carrying value of the assets and the present value of future cash flows. It is reasonably possible that a change in reserve or price estimates could occur in the near term and adversely impact management's estimate of future cash flows and consequently the carrying value of properties. In addition, under Hong Kong GAAP, a subsequent increase in the recoverable amount of an asset (other than goodwill and available-for-sale equity investments) is reversed to the income statement to the extent that an impairment loss on the same asset was previously recognised as an expense when the circumstances and events that led to the write-down or write-off cease to exist. The reversal is reduced by the amount that would have been recognised as depreciation had the write-down or write-off not occurred. Under US GAAP, an impairment loss establishes a new cost basis for the impaired asset and the new cost basis should not be adjusted subsequently other than for further impairment losses. For the year ended December 31, 2005, an impairment of approximately RMB90,190,000 was recognised under Hong Kong GAAP and US GAAP. (iii) Acquisition of CNOOC Finance Under HK GAAP, the Company adopted the purchase method to account for the acquisition of 31.8% equity interest in CNOOC Finance in December 2003. Under the purchase method, the acquired results are included in the consolidated results of operations of the Company from the date of the acquisition. As the Company and CNOOC Finance are under common control of CNOOC, under US GAAP, the acquisition is considered to be a transfer of businesses under common control and the acquired assets and liabilities are accounted at historical cost in a manner similar to the pooling of interests method. Accordingly, the consolidated financial statements for all periods presented have been retroactively restated as if the current structure and operations had been in existence since inception. The cash consideration paid by the Company is treated as an equity transaction in the year of the acquisition for US GAAP purpose.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONT'D) (a) Net profit and net equity (continued) (iv) Accounting for convertible bonds With effect from January 1, 2005, under HKAS 32 Financial Instruments: Disclosure and Presentation, financial instruments with cash settlement options and other derivative components will need to be bifurcated into a debt component and a derivative component. The derivative component is marked to market at each balance sheet date and the differences will be charged/credited to the income statement. The debt component is stated at amortised cost. The requirements of HKAS 32 have been applied retrospectively with comparative amounts restated. Under US GAAP, convertible bonds are subject to different rules on the bifurcation of the debt and derivative components. However, there is no significant difference on the accounting treatment adopted under HK GAAP and US GAAP for the Group's convertible bonds. (v) Provision for dismantlement HK GAAP requires the provision for dismantlement to be recorded for a present obligation whether that obligation is legal or constructive. The associated cost is capitalized and the liability is discounted and accretion expense is recognised using the credit-adjusted risk-free interest rate in effect when the liability is initially recognised. Prior to 2003, the Company accrued for dismantlement costs on a unit-of-production basis under SFAS No.19, "Financial accounting and reporting by oil and gas producing companies" under US GAAP. The Company adopted SFAS No.143 "Accounting for asset retirement obligations" on January 1, 2003. SFAS No.143 requires that the fair value of a liability for an asset retirement obligation be recognised in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalised as part of the carrying amount of long-lived asset. The liability is discounted and accretion expense is recognised using the credit-adjusted risk-free interest rate in effect when the liability is initially recognised. The impact of the adoption of SFAS No.143 is included in the cumulative effect of change in accounting policy for dismantlement liabilities below.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONT'D) (b) Comprehensive income According to SFAS No. 130, "Reporting comprehensive income", the Group is required to include a statement of other comprehensive income for revenues and expenses, gains and losses which under US GAAP are included in comprehensive income and excluded from net income. 2003 2004 2005 RMB'000 RMB'000 RMB'000 ------------------------------------------ Net income under US GAAP 11,979,509 16,176,492 25,343,158 Other comprehensive income: Foreign currency translation adjustments 36,243 (42,301) (493,289) Unrealised gains /(losses) on available-for-sale investments/Short term investments 21,503 (25,228) 69,069 Less: Reclassification adjustment for gains included in net income (27,088) (2,972) (20,036) ------------------------------------------ Comprehensive income under US GAAP 12,010,167 16,105,991 24,898,902 ------------------------------------------ Roll forward of accumulated other comprehensive income components are as follows: Unrealised Foreign gains on Accumulated currency available other translation -for-sale comprehensive adjustments investments income RMB'000 RMB'000 RMB'000 ------------------------------------------ Balance at January 1, 2003 (13,596) 53,821 40,225 Reversal of current year's realised gains -- (27,088) (27,088) Current year's change 36,243 21,503 57,746 ----------------------------------------- Balance at January 1, 2004 22,647 48,236 70,883 Reversal of current year's realised gains -- (2,972) (2,972) Current year's change (42,301) (25,228) (67,529) ----------------------------------------- Balance at December 31, 2004 (19,654) 20,036 382 Reversal of current year realised gains -- (20,036) (20,036) Current year's change (493,289) 69,069 (424,220) ----------------------------------------- Balance at December 31, 2005 (512,943) 69,069 (443,874) ----------------------------------------- F-74 CNOOC LIMITED AND ITS SUBSIDIARIES NOTES TO FINANCIAL STATEMENTS (All amounts expressed in Renminbi unless otherwise stated) 38. SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONT'D) (c) Use of estimates in the preparation of financial statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The most significant estimates pertain to proved oil and gas reserve volumes and the future development, provision for dismantlement as well as estimates relating to certain oil and gas revenues and expenses. Actual amounts could differ from those estimates and assumptions. (d) Segment reporting The Group's segment information is based on the segmental operating results regularly reviewed by the Group's chief operating decision maker. The accounting policies used are the same as those used in the preparation of the Group's consolidated Hong Kong GAAP financial statements. (e) Impact of Recently Issued Accounting Standards In December 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No.153, "Exchange of Non-monetary Asset an amendment of APB Opinion No.29".This Statement, which address the measurement of exchange of non-monetary assets, is effective prospectively for non-monetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. The adoption of this Statement is not expected to impact the Company's consolidated financial position or results of operations. In December 2004, the FASB issued Statement No. 123 (revised 2004), "Share Based Payment" (FAS No.123R), which replaces FAS No.123 and superseded APB Opinion No.25, "Accounting For Stock Issued to Employees". FAS No.123R requires all share-based payments to employees, including grants of employee stock options, to be recognised in the financial statement based on their fair values beginning with the first interim period after June 15, 2005, with early adoption encouraged. Under the SEC's rule, FAS No.123R is now effective for the Company beginning January 1, 2006, The proforma disclosures previously permitted under FAS No 123 no longer will be an alternative to financial statement recognition. The Company believes the adoption of the FAS No. 123R will have no material impact on its consolidated financial statement as the Company currently accounts for the stock options under the fair value recognition provision of FAS No. 123. In 2005, the FASB has finalized an amendment to statement No.19, "Financial Accounting and Reporting by Oil and Gas Producing Companies" ("FAS No. 19") that change the way oil and gas producers account for deferred exploratory drilling costs. The new standard would relax the one-year limitation, so long as oil and gas reserves have been discovered and an enterprise "is making sufficient progress assessing the reserves and the economic and operating viability of the project." We believe the adoption of amendment to FAS No. 19 will have no material impact on its consolidated financial position or results of operations.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONT'D) (e) Impact of Recently Issued Accounting Standards (continued) In March 2005, the FASB issued FASB Interpretation Number 47("FIN No.47"), "Accounting for conditional asset retirement obligations". The interpretation clarifies the requirement to record abandonment liabilities stemming from legal obligations when the retirement depends on a conditional future event. FIN No.47 requires that the uncertainty about the timing or method of settlement of a conditional retirement obligation be factored into the measurement of the liability when sufficient information exists. FIN No.47 is effective for fiscal years ending after December 15, 2005 and application of the interpretation did not change how abandonment obligations are currently calculated by the Company. In May 2005, the FASB issued FAS No. 154, i(degree)Accounting Changes and Error Corrections,i+/- a replacement of APB Opinion No. 20, i(degree)Accounting Changesi+/- and FAS No. 3, i(degree)Reporting Accounting Changes in Interim Financial Statementsi+/- (i(degree)FAS No. 154i+/-). FAS No.154 changes the requirements for the accounting for, and reporting of, a change in accounting principle. Previously, voluntary changes in accounting principles were generally required to be recognised by way of a cumulative effect adjustment within net income during the period of the change. FAS No. 154 requires retrospective application to prior periodsi- financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. FAS No. 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the statement does not change the transition provisions of any existing accounting pronouncements. The Company does not believe adoption of FAS No. 154 will have a material effect on its financial position, cash flows or results of operations. In February 2006, the FASB issued FAS No. 155 "Accounting for Certain Hybrid Financial Instruments, an amendment of FASB Statements No. 133 and 140" ("FAS No.155"). FAS No. 155 clarifies certain issues relating to embedded derivatives and beneficial interests in securitized financial assets, including permitting fair value measurement for any hybrid financial instrument that contains an embedded derivative, eliminating the prohibition on a qualifying special-purpose entity from holding certain derivative instruments, and providing clarification that concentrations of credit risk in the form of subordination are not embedded derivatives. The provisions of FAS No. 155 are effective for all financial instruments acquired or issued after fiscal years beginning after September 15, 2006. The Company does not believe adoption of FAS No. 155 will have a material effect on its financial position, cash flows or results of operations.

The disclosures are categorized by the geographical areas in which the Group conducts oil and gas activities. Except for PRC and Indonesia, the information on the other geographical areas, such as Australia, Myanmar and Morocco, etc., are combined in the following disclosures as "Others", among which all the other projects are still in exploration or joint study stage except that the North West Shelf Project in Australia is in development stage. (a) Reserve quantity information Crude oil and natural gas reserve estimates are determined through analysis of geological and engineering data which appear, with reasonable certainty, to be recoverable at commercial rates in the future from known oil and natural gas reservoirs under existing economic and operating conditions. Estimates of crude oil and natural gas reserves have been made by independent engineers. The Group's net proved reserves consist of its percentage interest in reserves, comprised of a 100% interest in its independent oil and gas properties and its participating interest in the properties covered under the production sharing contracts in PRC, less (a) an adjustment for the Group's share of royalties payable by the Group to the PRC government and the Group's participating interest in share oil payable to the PRC government under the production sharing contracts, and less (b) an adjustment for production allocable to foreign partners under the PRC production sharing contracts as reimbursement for exploration expenses attributable to the Group's participating interest, and plus (a) its participating interest in the properties in Australia, and (b) the participating interest in the properties covered under the production sharing contracts in Indonesia less an adjustment of share oil attributable to the Indonesian government and the domestic market obligation.

include estimated future dismantlement costs of dismantling offshore oil platforms and gas properties. ** The amounts include prepayments made in 2004 for the NWS Project of RMB 4,693,809,000 and a tax refund of RMB152,993,000 related to the acquisition of the NWS Project received in 2005. (e) Standardised measure of discounted future net cash flows and changes therein In calculating the standardised measure of discounted future net cash flows, year-end constant price and cost assumptions were applied to the Group's estimated annual future production from proven reserves to determine future cash inflows. Year end average realised oil prices used in the estimation of proved reserves and calculation of the standardised measure were US$48 as at December 31, 2005 (2004: US$32; 2003: US$30). Future development costs are estimated based upon constant price assumptions and assume the continuation of existing economic, operating and regulatory conditions. Future income taxes are calculated by applying the year-end statutory rate to estimate future pre-tax cash flows after provision for the tax cost of the oil and natural gas properties based upon existing laws and regulations. The discount was computed by application of a 10% discount factor to the estimated future net cash flows. Management believes that this information does not represent the fair market value of the oil and natural gas reserves or the present value of estimated cash flows since no economic value is attributed to potential reserves, the use of a 10% discount rate is arbitrary, and prices change constantly from year-end levels.
