Item 2. Identity and Background

     (a) This Schedule 13D is filed by (i) Encore Acquisition Company, a Delaware corporation (“EAC”), (ii) Encore Partners LP Holdings LLC, a Delaware limited liability company (“LP Holdings”), (iii) EAP Operating, Inc., a Delaware corporation (“EAP Operating”), (iv) EAP Properties, Inc., a Delaware corporation (“EAP Properties”), and (v) Encore Operating, L.P., a Texas limited partnership (“Encore Operating” and, together with EAC, LP Holdings, EAP Operating and EAP Properties, the “Reporting Persons”).

          EAC is a publicly traded oil and natural gas company. EAC is the sole member of LP Holdings and is the sole shareholder of each of EAP Operating and EAP Properties. EAP Operating and EAP Properties are the sole general partner and sole limited partner, respectively, of Encore Operating. Accordingly, the Reporting Persons are hereby filing a joint Schedule 13D.

          Encore Energy Partners GP LLC, a Delaware limited liability company (the “General Partner”), is the general partner of the Issuer.

     (b) The business address of each of the Reporting Persons is 777 Main Street, Suite 1400, Fort Worth, Texas, 76102.

     (c) The principal business of EAC is to engage in the acquisition and development of oil and natural gas reserves from onshore fields in the United States. LP Holdings’ principal business is to hold a limited partner interest in the Issuer. EAP Operating and EAP Properties’ principal businesses are to hold a general partner interest and a limited partner interest, respectively, in Encore Operating. Encore Operating’s principal business is to hold oil and natural gas properties and related assets of EAC and a limited partner interest in the Issuer.

     (d) – (e) During the past five years, none of the Reporting Persons have (i) been convicted in a criminal proceeding nor (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of which 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.

     (f) Not applicable.

     In accordance with the provisions of General Instruction C to Schedule 13D, information concerning the executive officers, directors and each person controlling the Reporting Persons, as applicable (collectively, the “Listed Persons”), required by Item 2 of Schedule 13D is provided on Schedule 1 and is incorporated by reference herein. To the Reporting Persons’

knowledge, none of the Listed Persons have been, during the last five years, (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (ii) a party to a civil proceeding of 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 3. Source and Amount of Funds or Other Consideration

     The Issuer was formed in February 2007 as a Delaware limited partnership to acquire, exploit and develop oil and natural gas properties and to acquire, own and operate related assets. Upon the formation of the Issuer, LP Holdings and the General Partner contributed $588 and $12, respectively, to the Issuer. Prior to the Issuer’s initial public offering of 9,000,000 Common Units (the “Offering”), LP Holdings’ limited partner interest in the Issuer was converted to 10,279,639 Common Units.

     At the closing of the Offering, the following actions, among others, occurred:

	•		Encore Operating transferred certain oil and natural gas assets and related assets located in the Permian Basin of West Texas to the Issuer in exchange for 4,043,478 Common Units; and
	•		through a series of transactions, 260,870 Common Units owned by LP Holdings were transferred to the General Partner, which the General Partner exchanged for an equal number of general partner units in the Issuer in order to maintain its 2% general partner interest.

     In the event the underwriters exercise their option to purchase additional Common Units in connection with the Offering, additional Common Units owned by LP Holdings will be transferred to the General Partner, which will exchange them for an equal number of general partner units in the Issuer in order to maintain its 2% general partner interest.

Item 4. Purpose of Transaction

     The Reporting Persons acquired the Common Units reported herein solely for investment purposes. The Reporting Persons may make additional purchases of Common Units either in the open market or in private transactions depending on the Reporting Person’s business, prospects and financial condition, the market for the Common Units, general economic conditions, stock market conditions and other future developments.

     The following describes plans or proposals that the Reporting Persons may have with respect to the matters set forth in Item 4(a)-(j) of Schedule 13D:

     (a) None.

     (b) None.

     (c) None.

     (d) The General Partner is not elected by the Issuer’s unitholders and will not be subject to re-election on a regular basis in the future. The Issuer’s unitholders will also not be entitled to elect the directors of the General Partner or directly or indirectly participate in the Issuer’s management or operation. As owner of the General Partner, EAC will have the ability to elect all the members of the board of directors of the General Partner.

     (e) EAC as indirect owner of the General Partner of the Issuer, may cause the Issuer to change its dividend policy or its capitalization, through the issuance of debt or equity securities, from time to time in the future.

The Reporting Persons may change their plans or proposals in the future. In determining from time to time whether to sell the Common Units reported as beneficially owned in this Schedule 13D (and in what amounts) or to retain such securities, the Reporting Persons will take into consideration such factors as they deem relevant, including the business and prospects of the Issuer, anticipated future developments concerning the Issuer, existing and anticipated market conditions from time to time, general economic conditions, regulatory matters, and other opportunities available to the Reporting Persons. The Reporting Persons reserve the right to acquire additional securities of the Issuer in the open market, in privately negotiated transactions (which may be with the Issuer or with third parties) or otherwise, to dispose of all or a portion of their holdings of securities of the Issuer or to change their intention with respect to any or all of the matters referred to in this Item 4.

     Depending on the factors described in the preceding paragraph, and other factors that may arise in the future, the Listed Persons may be involved in such matters and, depending on the facts and circumstances at such time, may formulate a plan with respect to such matters. In addition, the Listed Persons may entertain discussions with, and proposals to, the Issuer, to other unitholders of the Issuer or to third parties.
