SCHEDULE 13D UNDER THE SECURITIES EXCHANGE ACT OF 1934 This Amendment No. 2 to Statement on Schedule 13D amends the Schedule 13D filed by Patterson-UTI Energy, Inc., a Delaware corporation (the "Reporting Person") on June 21, 2002 (the "Initial Schedule 13D"), as amended by Amendment No. 1 to the Initial Schedule 13D filed by the Reporting Person on October 31, 2002 ("Amendment No. 1"). All capitalized terms used herein but not otherwise defined herein shall have the meanings given to them in the Initial Schedule 13D. ITEM 1. SECURITY AND ISSUER. No change since Amendment No. 1 ("No Change"). ITEM 2. IDENTITY AND BACKGROUND. No Change, except that Stephen J. DeGroat is no longer a Director of the Reporting Person and Terry H. Hunt was elected as a Director of the Reporting Person at the Annual Meeting of Stockholders of the Reporting Person held on April 30, 2003. The present principal occupation of Mr. Hunt is energy consultant and investor and his principal business address is 1500 Spring Mill Lane, Villanova, Pennsylvania 19085. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. The Reporting Person, the Issuer and Patterson-UTI Acquisition, LLC, a Texas limited liability company and a wholly owned subsidiary of the Reporting Person (the "Subsidiary"), entered into an Agreement and Plan of Merger dated as of May 26, 2003 (the "Merger Agreement"). Pursuant to the terms of the Merger Agreement, the Issuer will merge with and into the Subsidiary, with the Subsidiary as the surviving company (the "Merger"). Under the terms and subject to the conditions in the Merger Agreement, each issued and outstanding share of common stock, $.10 par value per share, of the Issuer (the "Common Stock"), not owned directly or indirectly by the Reporting Person or Issuer (except shares of Common Stock held by persons who object to the Merger, comply with all of the provisions of Texas law concerning the right of holders of shares of Common Stock to dissent from the Merger and require appraisal of their Common Stock), will be converted into the right to receive $9.09 in cash and 0.312166 of a share of common stock, $.01 par value per share, of the Reporting Person ("Reporting Person Common Stock"). The Reporting Person will pay each holder cash in lieu of any fractional shares. The cash component of the consideration will be funded from funds available on hand and under existing financing facilities and the Reporting Person Common Stock component will be derived from previously authorized but unissued shares of Reporting Person Common Stock. The foregoing description of the Merger Agreement is qualified in its entirety by the terms of the Merger Agreement, which is filed herewith as an exhibit and which is incorporated herein by reference to Exhibit 2.1 to the Form 8-K filed by the Issuer on May 27, 2003. Page 3 of 7 ITEM 4. PURPOSE OF TRANSACTION. Item 4 of Amendment No. 1 is hereby amended and restated in its entirety: The purpose of the transactions contemplated by the Merger Agreement is for the Reporting Person to acquire 100% of the Issuer through the Issuer merging with and into Subsidiary. (a) THE ACQUISITION BY ANY PERSON OF ADDITIONAL SECURITIES OF THE ISSUER, OR THE DISPOSITION OF SECURITIES OF THE ISSUER; Reporting Person has no present intention, plan, or proposal with respect to this paragraph, other than as contemplated by the Merger Agreement. (b) AN EXTRAORDINARY CORPORATE TRANSACTION, SUCH AS A MERGER, REORGANIZATION OR LIQUIDATION, INVOLVING THE ISSUER OR ANY OF ITS SUBSIDIARIES; As more fully described in Item 3 above, the Issuer will merge with and into the Subsidiary, with the Subsidiary as the surviving entity, upon the effective time of the Merger as described in the Merger Agreement.

(d) ANY CHANGE IN THE PRESENT BOARD OF DIRECTORS OR MANAGEMENT OF THE ISSUER, INCLUDING ANY PLANS OR PROPOSALS TO CHANGE THE NUMBER OR TERM OF DIRECTORS OR TO FILL ANY EXISTING VACANCIES ON THE BOARD; At the effective time of the Merger, the officers of the Subsidiary at the time of the Merger will become the officers of the surviving company. The surviving company will be a limited liability company and, therefore, will not have directors (or managers). (e) ANY MATERIAL CHANGE IN THE PRESENT CAPITALIZATION OR DIVIDEND POLICY OF THE ISSUER; Reporting Person has no present intention, plan or proposal with respect to this paragraph. (f) ANY OTHER MATERIAL CHANGE IN THE ISSUER'S BUSINESS OR CORPORATE STRUCTURE, INCLUDING BUT NOT LIMITED TO, IF THE ISSUER IS A REGISTERED CLOSED-END INVESTMENT COMPANY, ANY PLANS OR PROPOSALS TO MAKE ANY CHANGES IN ITS INVESTMENT POLICY FOR WHICH A VOTE IS REQUIRED BY SECTION 13 OF THE INVESTMENT COMPANY ACT OF 1940; Reporting Person has no present intention, plan or proposal with respect to this paragraph.

(h) CAUSING A CLASS OF SECURITIES OF THE ISSUER TO BE DELISTED FROM A NATIONAL SECURITIES EXCHANGE OR TO CEASE TO BE AUTHORIZED TO BE QUOTED IN AN INTER-DEALER QUOTATION SYSTEM OF A REGISTERED NATIONAL SECURITIES ASSOCIATION; After the effective time of the Merger, the common stock of the Issuer shall cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association. (i) A CLASS OF EQUITY SECURITIES OF THE ISSUER BECOMING ELIGIBLE FOR TERMINATION OF REGISTRATION PURSUANT TO SECTION 12(g)(4) OF THE ACT; AND After the effective time of the Merger, the equity securities of the Issuer shall become eligible for termination of registration pursuant to Section 12(g)(4) of the Act. (j) ANY ACT SIMILAR TO ANY OF THOSE ENUMERATED ABOVE. Reporting Person has no present intention, plan or proposal with respect to this paragraph. The responses to (a)-(j) above are qualified in their entirety by the terms and conditions of the Merger Agreement which describes the Merger pursuant to which the Reporting Person will indirectly acquire 100% of the Issuer. ITEM 5. INTEREST IN SECURITIES OF ISSUER. Item 5 of Amendment No. 1 is hereby amended and restated in its entirety: The Reporting Person beneficially owns 1,058,673 shares of the Common Stock, which represents approximately 19.3% of the Issuer's outstanding shares of Common Stock at the close of business on May 23, 2003, based on information provided by the Issuer to the Reporting Person on May 26, 2003. The Reporting Person has sole power to vote or to direct the vote of, and sole power to dispose or to direct the disposition of, 1,058,673 shares of Common Stock beneficially owned by the Reporting Person.
