This Amendment No. 5 to Schedule 13D amends and supplements the initial statement on Schedule 13D filed jointly by Sanchez Energy Partners I, LP, a Delaware limited partnership (“SEP I”); SEP Management I, LLC, a Delaware limited liability company (“SEP Management”); Sanchez Oil & Gas Corporation, a Delaware corporation (“SOG”); Antonio R. Sanchez, III; and A. R. Sanchez, Jr. with the SEC on August 19, 2013, as amended by Amendment No. 1 to Schedule 13D filed with the SEC on April 7, 2014, as further amended by Amendment No. 2 to Schedule 13D filed with the SEC on May 16, 2014, as further amended by Amendment No. 3 to Schedule 13D filed with the SEC on December 24, 2014 and as further amended by Amendment No. 4 to Schedule 13D filed with the SEC on March 24, 2015 (as further amended or amended and restated hereby, the “Schedule 13D”) and relates to the beneficial ownership by the Reporting Persons of common units of Issuer. Except as otherwise set forth herein, the Schedule 13D remains in full force and effect.  All capitalized terms used in this Amendment No. 5 have the same meaning as those set forth in the Schedule 13D. This Amendment is being filed to disclose the disposition by SEP I of common units representing limited partner interests (“Units”) in Sanchez Production Partners LP (“Issuer”) to its partners.

Item 3. Source and Amount of Funds or Other Consideration.

On July 27, 2015, SEP I distributed its 5,951,482 Units to its partners (the “Distribution”).  SEP Management is SEP I’s general partner, and SEP I’s limited partners include SOG, San Juan Oil & Gas No. 2, Ltd., a Texas limited partnership (“San Juan”), and Sanexco, Ltd., a Texas limited partnership (“Sanexco”), among others; simultaneously with the Distribution, San Juan and Sanexco made pro rata distributions of the Units received by them to their respective partners, including Sanchez Management Corporation, a Texas corporation (“SMC”). On July 27, 2015, simultaneously with such distributions, SMC made a pro rata distribution for no consideration of the 10,596 Units beneficially owned by it to its sole shareholder, A.R. Sanchez, Jr. The distributions were a return on such partners’ or shareholder’s, as applicable, capital contributions, thus no consideration was paid for the Units distributed.

On August 3, 2015, the Issuer effected a reverse split of its Units, whereby each holder of Units immediately prior to the reverse split received one Unit for each ten Units it owned (the “Reverse Split”). The number of Units shown to be beneficially owned by the Reporting Persons in this Schedule 13D reflects the Reverse Split. As a result of the Reverse Split, the number of Units was reduced to approximately 3,145,060.

Item 4. Purpose of Transaction.

The Reporting Persons acquired the securities reported in this Schedule 13D solely for investment purposes. The Reporting Persons may make additional purchases or dispositions of Issuer’s securities either in the open market or in private transactions depending on the Reporting Person’s business, prospects and financial condition, the market for Issuer’s securities, general economic conditions, stock market conditions and other future developments.

Except as described in this Item 4, the Reporting Persons do not have, as of the date of this Schedule 13D, any plans or proposals that relate to or would result in any of the actions or events specified in clauses (a) through (i) of Item 4 of Schedule 13D. The Reporting Persons may change their plans or proposals in the future. In determining from time to time whether to sell or dispose of Issuer securities (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 Issuer, anticipated future developments concerning 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 Issuer in the open market, in privately negotiated transactions (which may be with Issuer or with third parties) or otherwise, to dispose of all or a portion of their holdings of securities of Issuer or to change their intention with respect to any or all of the matters referred to in this Item 4.

Depending on these factors, and other factors that may arise in the future, the Reporting Persons may be involved in such matters and, depending on the facts and circumstances at such time and subject to applicable law, may formulate a plan with respect to such matters.  In addition, the Reporting Persons may from time to time hold discussions with or make proposals to management of Issuer, the board of managers of Issuer, to other unitholders of Issuer or to third parties regarding such matters.

The information set forth in this Item 4 is subject to change, and there can be no assurances that the matters described in this Item 4 will occur or that any of the Reporting Persons will or will not take, or cause to be taken, any of the actions described above or any similar actions.
