The principal executive offices of the Issuer are located at 410 Seventeenth Street, Suite 2300, Denver, Colorado 80202. ITEM 2. IDENTITY AND BACKGROUND This Schedule 13D is being filed by ERI Investments, Inc., a Delaware corporation ("ERI"), Equitable Resources, Inc., a Pennsylvania corporation ("Equitable" and together with ERI, the "ERI Entities"), and the following individuals: Murry S. Gerber and David L. Porges. ERI's principal business is to serve as a holding company for various subsidiaries and affiliates of Equitable. The address of ERI's principal office is: 801 West Street, 2nd Floor, Wilmington, Delaware 19801. The principal business of Equitable is to serve as an integrated energy company with an emphasis on the Appalachian area natural gas supply, natural gas transmission and distribution and leading-edge energy management services for customers throughout the United States and selected foreign markets. The address of its principal office is: One Oxford Centre, 301 Grant Street, Suite 3300, Pittsburgh, Pennsylvania 15219. Murry S. Gerber, a director of the Issuer, is Chairman, President and Chief Executive Officer of Equitable. David L.

The address of each of Mr. Gerber and Mr. Porges is: One Oxford Centre, Suite 3300, 301 Grant Street, Pittsburgh, Pennsylvania 15219-6401. Mr. Gerber and Mr. Porges are United States citizens. Neither ERI, Equitable nor any of their respective directors, executive officers, members or managers, has, during the past five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or an 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 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION The shares of Common Stock to which this statement on Schedule 13D relates were acquired by means other than purchase. The method of acquisition is described in Item 4 below. ITEM 4. PURPOSE OF THE TRANSACTION On August 21, 2001, the stockholders of Belco Oil & Gas Corp., a Nevada corporation ("Belco"), and the stockholders of Westport Resources Corporation, a Delaware corporation ("Westport"), approved and adopted the Agreement and Plan of Merger dated as of June 8, 2001 6 7 (the "Merger Agreement") by and between Belco and Westport providing for the merger of Westport with and into Belco (the "Merger"). In connection with the Merger, Belco changed its name to Westport Resources Corporation ("New Westport" or the "Issuer"). As of August 21, 2001, the effective time of the Merger, Belco's common stock, par value $0.01 per share ("Belco Common Stock"), was no longer outstanding and was automatically cancelled and retired, and certificates evidencing shares of Belco Common Stock only represented the right to receive, without interest, shares of New Westport's common stock, par value $0.01 per share ("New Westport Common Stock"). In the Merger, Belco common stockholders received 0.4125 of a share of New Westport Common Stock for each share of Belco Common Stock they owned. The outstanding shares of Belco 6 1/2% Convertible Preferred Stock, par value $0.01 per share, remained outstanding and the existing ratio was adjusted so that holders would receive 0.465795 of a share of New Westport Common Stock for each share of Belco 6 1/2% Convertible Preferred Stock upon conversion. In addition, as of the effective time of the Merger, Westport's common stock, par value $0.01 per share ("Westport Common Stock") was no longer outstanding and was automatically cancelled and retired, and certificates evidencing shares of Westport Common Stock only represented the right to receive, without interest, shares of New Westport. Westport stockholders received one share of New Westport Common Stock for each share of Westport Common Stock they owned. Immediately prior to the Merger, Westport's stockholders approved the amendment to the Westport Resources Corporation 2000 Stock Incentive Plan ("Westport Stock Plan") to increase the number of shares of Westport Common Stock reserved for issuance under the Westport Stock Plan from 4,110,813 shares to 6,232,484 shares. Pursuant to the Merger Agreement, at the effective time of the Merger, the Westport Stock Plan was assumed and adopted by New Westport and each outstanding employee or director stock option of Westport granted under the Westport Stock Plan was assumed by New Westport and became an option to purchase an equivalent number of shares of New Westport Common Stock. In connection with the Merger, Belco's articles of incorporation and bylaws were amended to, among other things, change its name to "Westport Resources Corporation," decrease the number of authorized shares of the Issuer's common stock, create a classified board of directors, provide for indemnification of certain persons, including directors and officers of Belco and, after the Merger, New Westport, and elect not to be governed by the Nevada Revised Statutes "Combination" provisions. As a condition to the consummation of the Merger, each of the directors and officers of Belco resigned or was removed. Pursuant to the Merger Agreement, New Westport amended articles of incorporation, New Westport amended bylaws and the Shareholders Agreement (defined below), 11 directors were elected to serve on the New Westport board of directors. The directors were divided into three classes as follows: Class I: Class II: Class III: Laurence D. Belfer Alex M. Cranberg Robert A. Belfer James M. Funk David L. Porges Murry S. Gerber Peter R. Hearl Donald D. Wolf Michael Russell William F. Wallace Randy Stein Since the effective time of the Merger, New Westport is managed by the former executive management team of Westport. Grant W. Henderson, former President and Chief 7 8 Operating Officer of Belco, also joined the New Westport management team as Executive Vice President and General Manager of the Southern Division based in Dallas. Donald D. Wolf is the Chairman and Chief Executive Officer and Barth E. Whitham is President and Chief Operating Officer of New Westport. In connection with the Merger, certain stockholders of Westport and Belco entered into the Second Amended and Restated Stockholders Agreement, dated as of July 20, 2001 (the "Shareholders Agreement") attached hereto as Exhibit 10.2, among Westport, Belco, ERI, Westport Energy LLC, a Delaware limited liability company ("WELLC"), and certain stockholders of Belco specified in the Shareholders Agreement (the "Belfer Group"), pursuant to which, among other things, WELLC, ERI and the Belfer Group agreed to vote shares of the Issuer owned and controlled by them in a manner prescribed in the Shareholders Agreement to determine the composition of the board of directors of the Issuer. The Shareholders Agreement requires supermajority approval of the New Westport board of directors for actions of New Westport and its subsidiaries involving (i) issuance of additional shares of New Westport Common Stock (with some exceptions), (ii) incurrence of certain level of debt, and (iii) certain sale transactions. The Shareholders Agreement also contains provisions imposing restrictions, subject to certain conditions, on the right of each of ERI, WELLC and the Belfer Group to (i) acquire beneficial ownership of any additional securities or debt instruments of New Westport and its subsidiaries, or (ii) form a group (as such term is defined in Regulation 13D promulgated under the Securities Exchange Act of 1934, as amended) for such purpose, without the consent of the other parties to the Shareholders Agreement. In addition, pursuant to the Shareholders Agreement, WELLC, ERI and the Belfer Group were granted certain registration rights. Each of WELLC, ERI and the Belfer Group received unlimited piggyback registration rights. ERI and WELLC were granted three demand registration rights and the Belfer Group was granted two demand registration rights. In connection with registration rights received under the Shareholders Agreement, each of WELLC, ERI and the Belfer Group agreed to enter into holdback agreements if requested by the underwriters in underwritten offerings. The Shareholders Agreement became effective at the effective time of the Merger. The shares of New Westport Common Stock owned by the ERI Entities, Murry S. Gerber and David L. Porges (collectively, the "Equitable Parties") are being held for investment purposes. The Equitable Parties intend to review their investment in New Westport on the basis of various factors, including New Westport's business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for New Westport's securities in particular, as well as other developments and other investment opportunities. Based upon such review, the Equitable Parties will take such actions in the future as they deem appropriate in light of the circumstances existing from time to time. The Equitable Parties may acquire New Westport Common Stock or other securities of New Westport either in the open market or in privately negotiated transactions. Similarly, the Equitable Parties may determine to dispose of some or all of New Westport's securities currently owned by it or otherwise acquired by it, either in the open market (subject to applicable legal restrictions), or in registered or privately negotiated transactions. None of the Equitable Parties presently have any plans or intentions to acquire additional New Westport securities, other than as disclosed in this Item 4. The foregoing is subject to the terms of the Shareholders Agreement. 8 9 ITEM 5.
