This Amendment No. 1 to the statement on Schedule 13D originally filed on July 23, 1999, (the "Statement"), is filed by First Reserve Fund VII, Limited Partnership, a Delaware limited partnership ("Fund VII"), First Reserve Fund VIII, L.P., a Delaware limited partnership ("Fund VIII" and together with Fund VII, the "Funds"), First Reserve GP VII, L.P., a Delaware limited partnership ("GP VII"), First Reserve GP VIII, L.P., a Delaware limited partnership ("GP VIII"), First Reserve Corporation, a Delaware corporation ("First Reserve" and together with GP VII, GP VIII and the Funds, the "Reporting Parties") and relates to the Common Stock, par value $0.001 per share (the "Common Stock"), of Superior Energy Services, Inc., a Delaware corporation (the "Issuer" or "Superior"). That Schedule 13D is hereby amended as set forth below. ITEM 2. IDENTITY AND BACKGROUND The text of Item 2 of the Statement is hereby deleted in its entirety and replaced with the following: This Schedule 13D is being filed jointly by First Reserve Fund VII, Limited Partnership, a Delaware limited partnership ("Fund VII"), First Reserve Fund VIII, L.P., a Delaware limited partnership ("Fund VIII" and together with Fund VII, the "Funds"), First Reserve GP VII, L.P., a Delaware limited partnership ("GP VII"), First Reserve GP VIII, L.P., a Delaware limited partnership ("GP VIII"), First Reserve Corporation, a Delaware corporation ("First Reserve" and together with GP VII, GP VIII and the Funds, the "Reporting Parties"). GP VII is the general partner of Fund VII, and First Reserve is the general partner of GP VII. GP VIII is the general partner of Fund VIII, and First Reserve is the general partner of GP VIII. The Reporting Parties, by and through the holdings of Fund VII and Fund VIII, directly own more than 5% of the issued and outstanding shares of Common Stock. The Funds are Delaware limited partnerships with a limited term of existence, the principal purpose of each of which is to make equity, equity-linked and debt investments in companies engaged in various energy and energy related activities. GP VII is a Delaware limited partnership, the sole purpose of which is to act as the general partner of Fund VII. GP VIII is a Delaware limited partnership, the sole purpose of which is to act as the general partner of Fund VIII. First Reserve is a Delaware corporation and is the general partner of both GP VII and GP VIII. The principal business of First Reserve is to provide investment management services to the Funds and to other investment funds managed by First Reserve. The principal business and office address of the Reporting Persons is One Lafayette Place, Greenwich, Connecticut 06830. Information with respect to the executive officers and directors of First Reserve, including name, business address, present principal occupation or employment and the organization in which such employment is conducted, and their citizenship is listed on the attached Schedule I, which is incorporated in this Schedule 13D by reference. William E. Macaulay and John A. Hill were previously included as Reporting Parties but are no longer Page 7 of 12

Reporting Parties because First Reserve does not believe that Mr. Macaulay and Mr. Hill share beneficial ownership of the shares. During the last five years, none of the Reporting Parties nor any executive officer or director of First Reserve has (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to a civil proceeding or a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. ITEM 4. PURPOSE OF TRANSACTION The text of Item 4 of the Statement is hereby amended by adding the following: On May 3, 2004, Fund VII sold 3,000,000 shares of Common Stock and Fund VIII sold 2,000,000 shares of Common Stock (the "Registered Shares"), pursuant to the effective Form S-3 Registration Statement No. 333-107749. Also on that date, Fund VII sold 780,000 shares of Common Stock and Fund VIII sold 520,000 shares of Common Stock in reliance on an exemption from registration pursuant to Rule 144 of the Securities Act of 1933, as amended (the "Rule 144 Shares"). All of the shares were sold by the Funds in broker's transactions at a price of $10.00 per share, with a commission of $0.05 per share. This Amendment No. 1 to Schedule 13D shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Registered Shares in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state. The offering of Registered Shares is being made only by means of a prospectus and prospectus supplement. A written prospectus meeting the requirements of Section 10 of the Securities Act of 1933 may be obtained from Superior Energy Services at 1105 Peters Road, Harvey, Louisiana 70058. The Reporting Parties intend to review their investment in Superior on a continuing basis and, depending upon the price of and other market conditions relating to the Common Stock, subsequent developments affecting Superior, Superior's business and prospects, other investment and business opportunities available to the Reporting Parties, general stock market and economic conditions, tax considerations and other factors deemed relevant, may decide to increase or decrease the size of their investment in Superior.

(e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER The text of Item 6 of the Statement is hereby amended by adding the following: Because the conditions in the Escrow Agreement regarding the average closing prices of Superior Common Stock were satisfied, all of the escrowed shares were released to Mr. Kotts on August 12, 1999.
