Formed in 1978 and reincorporated in 1993 as a Delaware corporation, we focus our contract drilling operations in: o Texas, o New Mexico, o Oklahoma, o Louisiana, o Mississippi, o Utah, and o Western Canada (Alberta, British Columbia and Saskatchewan). We currently have a drilling fleet of 324 drilling rigs, of which 287 operated in 2001. A drilling rig includes the structure, power source and machinery necessary to cause a drill bit to penetrate rock to a depth desired by the customer. We provide drilling fluids, completion fluids and related services to oil and natural gas producers in the Permian Basin of West Texas and Southeast New Mexico, South Texas, East Texas, Oklahoma, the Gulf Coast regions of Texas and Louisiana, and the Gulf of Mexico. Drilling and completion fluids are used by oil and natural gas operators during the drilling process to control pressure when drilling oil and natural gas wells. We also provide pressure pumping services in the Appalachian Basin. These services consist primarily of well stimulation and cementing for completion of new wells and remedial work on existing wells. To a lesser extent, we are engaged in the development, exploration, acquisition and production of oil and natural gas. Our oil and natural gas operations are not financially material and do not warrant further disclosure as a business segment. We conduct our operations through our subsidiaries. Our principal office is located at 4510 Lamesa Highway, Snyder, Texas 79550, and our telephone number is (915) 574-6300. You can obtain additional information about us in the reports and other documents incorporated by reference in this prospectus. See "Incorporation of Certain Documents by Reference" and "Where You Can Find More Information." 5 RISK FACTORS Ownership of shares of Patterson-UTI common stock involves certain risks. In determining whether to purchase shares being offered for sale under this prospectus, you should carefully consider the following risk factors and other information contained in or incorporated by reference in this prospectus or in any applicable prospectus supplement. PATTERSON-UTI IS DEPENDENT ON THE OIL AND NATURAL GAS INDUSTRY AND MARKET PRICES FOR OIL AND NATURAL GAS. DECLINES IN OIL AND NATURAL GAS PRICES HAVE ADVERSELY AFFECTED OUR OPERATIONS. Our revenue, profitability and rate of growth are substantially dependent upon the oil and natural gas industry and prevailing prices for oil and natural gas. In recent years, oil and natural gas prices and, therefore, the level of drilling, exploration, development and production, have been extremely volatile. Prices are affected by: o market supply and demand, o international military, political and economic conditions, and o the ability of the Organization of Petroleum Exporting Countries, commonly known as OPEC, to set and maintain production and price targets. All of these factors are beyond our control. Beginning in the third quarter of 2001 and continuing through the date of this prospectus, commodity price uncertainty has adversely affected our operations. We expect oil and natural gas prices to continue to be volatile and to affect our financial condition and operations and ability to access sources of capital. INDUSTRY CONDITIONS FOR CONTRACT DRILLING SERVICES HAVE BEEN POOR FOR MUCH OF THE TIME SINCE 1982. The contract drilling business experienced increased demand for drilling services from 1995 through most of 1997 due to higher oil and natural gas prices. The increase in demand returned, beginning in mid-1999 and continued through the second quarter of 2001. However, except for those periods and other occasional upturns, the market for onshore contract drilling services and the other services we provide has generally been depressed since 1982, when the number of operable land drilling rigs was at record levels. Since this time there have been substantially more drilling rigs available than necessary to meet demand in most operational and geographic segments of the North American land drilling industry. As a result, drilling contractors have had difficulty sustaining profit margins. In addition to adverse effects that future declines in demand could have on Patterson-UTI, ongoing factors which could adversely affect utilization rates and pricing, even in an environment of stronger oil and natural gas prices and increased drilling activity, include: o movement of drilling rigs from region to region, o reactivation of land-based drilling rigs, or o new construction of drilling rigs. We cannot predict either the future level of demand for our contract drilling services or future conditions in the oil and natural gas contract drilling business. 6 SHORTAGES OF DRILL PIPE, REPLACEMENT PARTS AND OTHER RELATED RIG EQUIPMENT ADVERSELY AFFECTS PATTERSON-UTI'S OPERATING RESULTS. During periods of increased demand for drilling services, the industry has experienced shortages of drill pipe, replacement parts and other related rig equipment. These shortages caused the price of these items to increase significantly and required that orders for the items be placed well in advance of expected use. These price increases and delays in delivery caused us to substantially increase capital expenditures in our contract drilling segment. Severe shortages could impair our ability to operate our drilling rigs. THE VARIOUS BUSINESS SEGMENTS IN WHICH WE OPERATE ARE HIGHLY COMPETITIVE WITH EXCESS CAPACITY WHICH MAY ADVERSELY AFFECT OUR OPERATING RESULTS. Our land drilling and pressure pumping businesses are intensely competitive due to the fact that the supply of available land drilling rigs and pressure pumping equipment exceeds the demand for those rigs and equipment. This excess capacity has resulted in substantial competition for drilling and pressure pumping contracts. The fact that drilling rigs and pressure pumping equipment are mobile and can be moved from one market to another in response to market conditions heightens the competition in the industry. Patterson-UTI believes that price competition for drilling and pressure pumping contracts will continue for the foreseeable future due to the existence of available rigs and pressure pumping equipment. In addition, some of our competitors have greater financial resources than we do which may enable them to: o better withstand industry downturns, o compete more effectively on the basis of price, and o acquire existing rigs or equipment or build new rigs or equipment. In recent years, many drilling and pressure pumping companies have consolidated or merged with other companies. Although this consolidation has decreased the total number of competitors, we believe the competition for drilling and pressure pumping services will continue to be intense. The drilling and completion fluids services industry is highly competitive. Price is generally the most important competitive factor in the industry. Other competitive factors include the availability of chemicals and experienced personnel, the reputation of the fluids services provider in the drilling industry and our relationship with existing customers. Some of our competitors have substantially greater resources and longer operating histories than we have. We believe that competition for drilling and completion fluids service contracts will continue to be intense. LABOR SHORTAGES ADVERSELY AFFECT OUR OPERATING RESULTS. During periods of increased demand for contract drilling services, the industry experiences shortages of qualified drilling rig personnel. During these periods, our ability to attract and retain sufficient qualified personnel to market and operate our drilling rigs is adversely affected. Labor shortages also cause wage increases, which impact our operating margins. CONTINUED GROWTH OF PATTERSON-UTI THROUGH RIG ACQUISITION IS NOT ASSURED. We have increased our drilling rig fleet over the past several years through mergers and acquisitions. In May 2001, UTI merged with Patterson in a so-called "merger of equals." The combination of the two companies doubled the number of our drilling rigs. The land drilling industry has 7 experienced significant consolidation over the past several years, and there can be no assurance that acquisition opportunities will continue to be available. Additionally, we are likely to continue to face intense competition from other companies for available acquisition opportunities. There can be no assurance that we will: o have sufficient capital resources to complete additional acquisitions, o successfully integrate acquired operations and assets, o be able to manage effectively the growth and increased size, o be successful in deploying idle or stacked rigs, o be able to maintain the crews and market share attributable to operating drilling rigs acquired, or o be successful in improving our financial condition, results of operation, business or prospects in any material manner as a result of any completed acquisition. We may incur substantial indebtedness to finance future acquisitions and also may issue equity securities or convertible securities in connection with any such acquisitions. Debt service requirements could represent a significant burden on our results of operations and financial condition and the issuance of additional equity could be dilutive to our existing stockholders. Also, continued growth could strain our management, operations, employees and resources. THE NATURE OF OUR BUSINESS OPERATIONS PRESENTS INHERENT RISKS OF LOSS, THAT, IF NOT INSURED OR INDEMNIFIED AGAINST COULD ADVERSELY AFFECT PATTERSON-UTI'S OPERATING RESULTS. Our operations are subject to many hazards inherent in the contract drilling, pressure pumping and drilling and completion fluids businesses, which in turn could cause personal injury or death, work stoppage or serious damage to our equipment. Our operations could also cause environmental and reservoir damages. We maintain insurance coverage and have indemnification agreements with many of our customers. However, there is no assurance that such insurance or indemnification agreements would adequately protect Patterson-UTI against liability from all consequences of the hazards. Additionally, there can be no assurance that insurance would be available to cover any or all of these risks, or, even if available, that insurance premiums or other costs would not rise significantly in the future, so as to make such insurance prohibitive. VIOLATIONS OF ENVIRONMENTAL LAWS AND REGULATIONS COULD MATERIALLY ADVERSELY AFFECT PATTERSON-UTI OPERATING RESULTS. The drilling of oil and natural gas wells is subject to various state, federal and foreign laws, rules and regulations. The cost to Patterson-UTI of compliance with these laws and regulations could be substantial. Failure to comply with these requirements could subject Patterson-UTI to substantial civil and criminal penalties. In addition, federal law imposes a variety of regulations on "responsible parties" related to the prevention of oil spills and liability for damages from such spills. Patterson-UTI, as an owner and operator of land-based drilling rigs may be deemed to be a responsible party under federal laws. Our operations and facilities are subject to numerous state and federal environmental laws, rules and regulations, including, without limitation, laws concerning the containment and disposal of hazardous substances, oil field waste and other waste materials, the use of underground storage tanks and the use of underground injection wells. We generally try to require our customers to contractually assume responsibility for compliance with environmental regulations, however, we are not always successful in shifting all of those risks, nor is there any assurance that the applicable customer will be financially able to bear those risks assumed. 8 SOME OF OUR CONTACT DRILLING SERVICES ARE DONE UNDER TURNKEY AND FOOTAGE CONTRACTS, WHICH ARE FINANCIALLY RISKY. A portion of our contract drilling is done under turnkey contracts and footage contracts, which involve significant risks. Under turnkey contracts, we contract to drill a well to a certain depth under specified conditions at a fixed price. Under footage contacts, we contract to drill a well to a certain depth under specified conditions at a fixed price per foot. The risk to us under these types of drilling contracts are greater than on a well drilled on a daywork basis. Unlike daywork contracts, we must bear the cost of performing drilling services until the target depth is reached. We must also make significant up-front working capital commitments prior to receiving payment. In addition, we must assume most of the risk associated with the drilling operations, generally assumed by the operator of the well on a daywork contract, including blowouts, loss of hole from fire, machinery breakdowns and abnormal drilling conditions. Accordingly, if severe drilling problems are encountered in drilling wells under such contracts, we could suffer substantial losses. ANTI-TAKEOVER MEASURES IN OUR CHARTER DOCUMENTS AND UNDER STATE LAW COULD DISCOURAGE AN ACQUISITION OF PATTERSON-UTI AND THEREBY AFFECT THE RELATED PURCHASE PRICE. Patterson-UTI, as a Delaware corporation, is subject to the Delaware General Corporation Law, including Section 203, an anti-takeover law enacted in 1988. We have also enacted certain anti-takeover measures, including a stockholders' rights plan. In addition, our board of directors has the authority to issue up to one million shares of preferred stock and to determine the price, rights (including voting rights), conversion ratios, preferences and privileges of that stock without further vote or action by the holders of the common stock. As a result of these measures and others, potential acquirers of Patterson-UTI may find it more difficult or be discouraged from attempting to effect an acquisition transaction with us. This may deprive holders of our securities of certain opportunities to sell or otherwise dispose of the securities at above-market prices pursuant to any such transactions. WE HAVE PAID NO DIVIDENDS ON OUR COMMON STOCK AND HAVE NO PLANS TO PAY DIVIDENDS. We have not declared or paid cash dividends on our common stock in the past. We do not expect to declare or pay any cash dividends on our common stock in the foreseeable future. The terms of our existing credit facility limit the payment of dividends without the prior written consent of the lenders. USE OF PROCEEDS We will not receive any proceeds from the sale of our common stock by the selling stockholders. DIVIDEND POLICY Patterson-UTI has not paid cash dividends on our common stock in the past and does not expect to pay any cash dividends on the common stock in the foreseeable future. Instead, we intend to retain our earnings to support the operations and growth of our businesses. Any future cash dividends would depend on future earnings, capital requirements, Patterson-UTI's financial condition and other factors deemed relevant by our Board of Directors. In addition, the terms of our existing credit facility limit the payment of dividends without the prior written consent of the lenders. 9 SELLING STOCKHOLDERS The following table sets forth the name of each selling stockholder, the total number of shares of our common stock beneficially owned by each selling stockholder as of June 11, 2002, and the total number of shares that each selling stockholder may offer and sell pursuant to this prospectus.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation Law (the "DGCL") provides for indemnification by a corporation of costs incurred by directors, employees and agents in connection with an action, suit or proceeding brought by reason of their position as a director, employee or agent. The person being indemnified must have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation. The DGCL provides that a corporation may advance payment of expenses. The DGCL further provides that the indemnification and advancement of expenses provisions of the DGCL will not be deemed exclusive of any other rights to which these indemnifications or advancements of expenses may be entitled under bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action under official capacity and as to action in another capacity when holding such office. In addition to the general indemnification section, Delaware law provides further protection for directors under Section 102(b)(7) of the DGCL. This section was enacted in June 1986 and allows a Delaware corporation to include in its certificate of incorporation a provision that eliminates and limits certain personal liability of a director for monetary damages for certain breaches of the director's fiduciary duty of care, provided that any such provision does not (in the words of the statute) do any of the following: [E]liminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of this Title (dealing with willful or negligent violation of the statutory provision concerning dividends and stock purchases and redemptions), or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective.... II-1 The Board of Directors is empowered to make other indemnification as authorized under any bylaw, agreement, the Certificate of Incorporation, Bylaws or corporate resolution so long as the indemnification is consistent with the DGCL. Patterson-UTI's Restated Certificate of Incorporation, as amended, provides that, to the fullest extent permitted by the DGCL, a director of Patterson-UTI will not be liable to Patterson-UTI or its stockholders for monetary damages for breach of fiduciary duty as a director. Patterson-UTI's Amended and Restated Bylaws provide that Patterson-UTI, to the maximum extent and in the manner permitted by the DGCL, shall indemnify each of its directors and officers against expenses (including attorneys' fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was an agent of Patterson-UTI, provided however, that Patterson-UTI may modify the extent of such indemnification by individual contracts with its directors and executive officers and, provided further, that Patterson-UTI shall not be required to indemnify any director or officer in connection with any proceeding (or part thereof) initiated by such person unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized in advance by the board of directors of Patterson-UTI, (iii) such indemnification is provided by Patterson-UTI, in its sole discretion, pursuant to the powers vested in Patterson-UTI under the DGCL or (iv) such indemnification is required to be made pursuant to an individual contract. Patterson-UTI's Amended and Restated Bylaws also provide that Patterson-UTI shall advance the payment of expenses. Patterson-UTI maintains director and officer liability insurance covering director and officer indemnification. Patterson-UTI also has an Indemnity Agreement with each of its directors and executive officers. The standard for indemnification under the Indemnity Agreement is substantially the same as under Patterson-UTI's Amended and Restated Bylaws, as amended. The Indemnity Agreement, however, provides for the creation of a trust account in the event of a "change in control" (as defined in the Indemnity Agreement), funded in an amount sufficient to reasonably satisfy any and all expenses incurred by a director or executive officer in connection with investigating, preparing for, participating in, and/or defending any proceeding relating to any Indemnifiable Event (as defined in the Indemnity Agreement). The trustee of such trust account is to be selected by the director or executive officer receiving the indemnity under the Indemnity Agreement. In the Agreement and Plan of Merger between Patterson Energy, Inc. and UTI Energy Corp. dated as of February 4, 2001, pursuant to which UTI Energy Corp. ("UTI") merged with and into Patterson Energy, Inc. with Patterson-UTI as the surviving corporation ("Merger"), Patterson-UTI agreed to indemnify the former officers and directors of UTI from liabilities arising out of actions or omissions in their capacity as such prior to the effective time of the Merger, and advance reasonable litigation expenses incurred in connection with such actions or omissions, to the full extent permitted under UTI's certificate of incorporation and bylaws. Further, for a period of six years after the effective time of the Merger, Patterson-UTI will provide the former officers and directors of UTI with an insurance and indemnification policy that provides coverage through the effective time of the Merger; provided that the maximum aggregate amount of premiums that Patterson-UTI will be required to pay to provide and maintain this coverage does not exceed $300,000 per year.

Patterson-UTI hereby undertakes: (a) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the Prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information II-3 set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of such securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (1)(a)(i) and (1)(a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by Patterson-UTI pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement. (b) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (d) That, for purposes of determining any liability under the Securities Act of 1933, each filing of Patterson-UTI's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 2. Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Securities Act") may be permitted to directors, officers and controlling persons of Patterson-UTI pursuant to the foregoing provisions, or otherwise, Patterson-UTI has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Patterson-UTI of expenses incurred or paid by a director, officer or controlling person of Patterson-UTI in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, Patterson-UTI will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. II-4 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, Patterson-UTI certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Snyder, State of Texas, on the 12th day of June, 2002.
