Whiting Petroleum’s 2003 Net Income Up 137%;
Sets Company Records for Reserves, Production and Net Cash Flow From Operations

DENVER – February 25, 2004 – (PR Newswire) – Whiting Petroleum Corporation (NYSE: WLL) today reported net income of $18.3 million, or $0.98 per basic share for the year ended December 31, 2003. This compares to 2002 net income of $7.7 million, or $0.41 per basic share.

Whiting’s 2003 results were impacted by one-time charges totaling $10.6 million net of income taxes. The charges consisted of $6.7 million ($10.9 million pre-tax paid by Whiting’s former parent company with a $4.2 million capital contribution and $6.7 million of WLL common stock) accounting for compensation paid under the Company’s Phantom Equity Plan in connection with the Company’s initial public offering and $3.9 million for the adoption of Financial Accounting Standards No. 143, “Accounting for Asset Retirement Obligations.”


Noteworthy events and results for 2003 included:

  The Company completed its initial public offering in November 2003 at $15.50 per share. Whiting’s stock price increased 18.7% by the close of the year.

  Total assets reached a company-record $536 million at December 31, 2003.

  Net cash flow provided by operating activities for 2003 was $96.4 million, an increase of $33.8 million from 2002.

  Proved reserves as of January 1, 2004 were 438.8 billion cubic feet equivalent (Bcfe), a company-record, 53% of which were natural gas.

  The pre-tax, SEC PV-10 value of the reserves on Jan. 1, 2004 was $784.6 million. This value was calculated using average wellhead prices in effect on December 31, 2003 of $29.43 per barrel and $5.52 per Mcf, inclusive of adjustments for quality and location.

  Production was 37.2 Bcfe, or 101.8 million cubic feet per day (MMcfe/d), both company records. Whiting’s 2004 drilling plans anticipate daily production to increase approximately 10%. However, producing property acquisitions, new field discoveries and improved recovery may all have a meaningful impact on the Company’s 2004 production rate.

Four Year Reserve Replacement 307%, 2003 FD&A cost of $0.86 per Mcfe

In announcing the year-end results, Whiting Chairman, President and Chief Executive Officer, James J. Volker, cited higher production volumes, solid cash operating margins, strong drilling results and improved financial position as primary accomplishments.

“Looking back over the past year, I’m encouraged by several significant achievements that continue our growth trend,” said Volker. “We drilled a single-year, company-record 72 wells with an 89% success rate. We instituted an aggressive plan for growth starting at the beginning of 2000, and since then have posted increases of 41% in annual production and 126% in total proved reserves. Whiting’s four-year production replacement average of 307% is a result of our growth plans; the four-year FD&A cost of $1.15 per Mcfe reflects our conscious efforts to economically execute our plans. We are especially proud of the 2003 reserve replacement rate of 170% at an FD&A cost of $0.86 per Mcfe. This reserve replacement rate and FD&A cost was accomplished with capital expenditures of only $52 million, or 39% of the average $134.7 million of capital expenditures in 2000 through 2002. This is a testament to the drilling and other well work conducted in 2003 when capital expenditures for acquisitions were reduced at the request of our former parent company in preparation for the IPO.” Reconciliations of FD&A and reserve replacement rates are included at the end of this press release.

Revenues, Production and Realized Commodity Prices

Oil and gas sales for the year, excluding the effects of hedging, were $175.7 million for 2003, compared to $122.7 million for 2002. Of the increase, $6.5 million was attributable to increased production volumes and $46.5 million was the result of improved commodity prices.

Crude oil sales in 2003 were 7,100 barrels of oil per day (Bbl/d), an increase of 12% compared to the 6,350 Bbl/d produced in 2002. The majority of the increase in crude oil sales was the result of successful drilling operations in North Dakota. Whiting’s realized average price per barrel, excluding hedging, in 2003 was $27.50, an increase of 18% over 2002‘s realized price of $23.35. Natural gas sales averaged 59.2 MMcf/d in 2003, compared to 58.5 MMcf/d in 2002. The average price received for the Company’s gas sales, excluding hedges, was $4.78 per Mcf in 2003, 49% more than the $3.21 per Mcf received in 2002.

Hedging Activities

Whiting hedged 41% of its natural gas production and 8% of its oil production in 2003, incurring a hedging loss of $8.7 million. The Company’s currently outstanding hedges are summarized below.

April - June, 2004 50,000  $ 28.00 / $ 35.40

Operating Expenses

Lease operating expense (LOE) was $1.16 per Mcfe for 2003 compared to $0.93 per Mcfe for 2002. This increase was due to recent acquisitions in North Dakota and Michigan, where local conditions create higher operating costs when compared to other areas of Whiting’s operations. Whiting expects LOE for 2004 to range from $1.08 to $1.12 per Mcfe. General and administrative expense was $0.34 per Mcfe for 2003. Due to projected additional costs of functioning as a public entity, Whiting projects its general and administrative costs for 2004 to approximate $0.36 to $0.39 per Mcfe.

2004 Capital Spending

Future growth of the Company is centered on having an average of 82% working interest control of our proved undeveloped drilling inventory. Whiting’s 2004 capital expenditure budget for development activities of $68 million will be split approximately 48% for development of its proved reserves and 52% to drill exploration prospects and develop currently unproven properties. Any acquisition opportunities would be in addition to the development budget.

Capital Resources and Liquidity

Whiting entered 2004 with $53.6 million of cash and working capital of $51.3 million. On February 17, 2004, Whiting paid down $40 million on its existing $350 million credit facility. After the repayment, the facility has an outstanding balance of $145 million and maintains the same borrowing base of $210 million. The debt repayment was provided entirely from cash on hand in excess of projected drilling and production needs.

“The reduction in long-term debt trims the Company’s 2004 interest payments by approximately $1.1 million,” said Volker. “We now have greater financial flexibility to grow Whiting’s assets and valuation for its shareholders.”
