AMENDMENT NO. 6 TO SCHEDULE 13D

This Amendment No. 6 to Schedule 13D (this “Amendment”) amends (where indicated) the Schedule 13D filed with the Securities and Exchange Commission on December 12, 2012 (as amended prior to this Amendment and, where applicable, as further amended hereby, the “Schedule 13D”), and relates to the beneficial ownership by the Reporting Persons of the common units representing limited partner interests of Western Midstream Partners, LP, a Delaware limited partnership (the “Issuer”).  Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Schedule 13D.  This Amendment is being filed by the Reporting Persons pursuant to their Joint Filing Agreement filed as Exhibit M to Amendment No. 5 to the Schedule 13D.  This Amendment is being filed to disclose material changes to the facts set forth in the Schedule 13D as a result of the consummation of the Merger (as defined in this Amendment). As a result of the Merger, Occidental (as defined in this Amendment), as the ultimate beneficial owner of the Reporting Persons’ interests in the Issuer, will file a Schedule 13D in respect of its ownership interests in the Issuer on behalf of itself and its applicable subsidiaries. The Reporting Persons will cease to file amendments to the Schedule 13D as of the date hereof.

Item 2.
Identity and Background

Item 2 of the Schedule 13D is hereby amended and supplemented by replacing Schedule I thereto with Schedule I hereto.

In accordance with the provisions of General Instruction C to Schedule 13D, information concerning the general partners, executive officers, board of 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 I and is incorporated by reference herein. To the Reporting Persons’ knowledge, none of the persons listed on Schedule I as a director or executive officer of Anadarko, WGR, AMH, WGRAH, KWC or AE&P has 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

Item 3 of the Schedule 13D is hereby amended by adding the following after the final paragraph:

The information provided or incorporated by reference in Item 4 below is hereby incorporated by reference into this Item 3.



Item 4.
Purpose of Transaction

Subsection (d) of Item 4 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(d) The information set forth in Item 4(j) is incorporated by reference into this Item 4(d).

Item 4 of the Schedule 13D is hereby amended by adding the following after the final paragraph of subsection (j):

On August 8, 2019, Occidental Petroleum Corporation, a Delaware corporation (“Occidental”), completed its previously announced acquisition of Anadarko Petroleum Corporation, a Delaware corporation (“Anadarko”), the indirect general partner and majority unitholder of the Issuer, through the merger of Baseball Merger Sub 1, Inc., a Delaware corporation and an indirect, wholly owned subsidiary of Occidental (“Merger Subsidiary”), with and into Anadarko (the “Merger”), with Anadarko surviving and continuing as the surviving corporation in the Merger. As a result of the Merger, Anadarko became an indirect, wholly owned subsidiary of Occidental.

At the effective time of the Merger, in accordance with the Agreement and Plan of Merger, dated May 9, 2019 (the “Merger Agreement”), by and among Anadarko, Occidental and Merger Subsidiary, each outstanding share of common stock of Anadarko (except as otherwise specified in the Merger Agreement) was converted into the right to receive $59.00 in cash and 0.2934 of a share of common stock of Occidental, plus cash in lieu of any fractional Occidental shares that otherwise would have been issued (the “Merger Consideration”). Occidental financed the cash portion of the Merger Consideration with the proceeds of the following debt and equity financings: (1) a $10.0 billion equity investment by Berkshire Hathaway Inc., (2) an $8.8 billion senior unsecured term loan credit facility, with Citibank, N.A., as administrative agent, and certain financial institutions, as lenders, and (3) the issuance of senior unsecured notes in an aggregate principal amount of $13.0 billion.

As a result of the Merger, Occidental (1) indirectly, wholly owns and controls Western Midstream Holdings, LLC (the “General Partner”), the Issuer’s general partner, and (2) indirectly holds approximately 55.5% of the Issuer’s limited partner units.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached as Exhibit V hereto, and is incorporated by reference herein.

As a result of the Merger, Occidental, as the ultimate beneficial owner of the Reporting Persons’ interests in the Issuer, will file a Schedule 13D in respect of its ownership interest in the Issuer on behalf of itself and its applicable subsidiaries. The Reporting Persons will cease to file amendments to the Schedule 13D as of the date hereof.

On August 8, 2019, in connection with the consummation of the Merger, Milton Carroll, Benjamin M. Fink, Robin H. Fielder, Robert G. Gwin, Daniel E. Brown, Mitchell W. Ingram and Amanda M. McMillian resigned from the board of directors (the “Board”) of the General Partner effective immediately following the consummation of the Merger.



On August 8, 2019, in connection with the consummation of the Merger, Occidental appointed Mses. Marcia E. Backus and Jennifer M. Kirk and Messrs. Oscar K. Brown, Peter J. Bennett, Michael P. Ure and Glenn M. Vangolen to the Board. Additionally, Mr. Vangolen was appointed as Chairman of the Board.

On August 8, 2019, in connection with the consummation of the Merger, the Board appointed Michael P. Ure as President and Chief Executive Officer, and Craig W. Collins as Senior Vice President and Chief Operating Officer, to succeed Robin H. Fielder and Gennifer F. Kelly, respectively.

Item 5.
Interest in Securities of the Partnership.

Subsection (d) of Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(d)
The Reporting Persons have the right to receive distributions from, and the proceeds from the sale of, the respective common units reported by such persons on the cover pages of the Schedule 13D and in this Item 5.  See Schedule I for the information applicable to the Listed Persons.  Except for the foregoing, no other person is known by the Reporting Persons to have the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of, common units beneficially owned by the Reporting Persons or, to the Reporting Persons’ knowledge, the Listed Persons other than, as a result of the Merger, Occidental and its subsidiaries.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 is hereby amended by adding the following:

The information provided or incorporated by reference in Item 4 above is hereby incorporated by reference into this Item 6.

Item 7.
Material to be Filed as Exhibits.

This Amendment supplements Item 7 of the Schedule 13D by inserting the following paragraph after the last paragraph of Item 7 of the Schedule 13D.

Exhibit V
Agreement and Plan of Merger, dated as of May 9, 2019, among Occidental Petroleum Corporation, Baseball Merger Sub 1, Inc. and Anadarko Petroleum Corporation (incorporated by reference to Exhibit 2.1 of Occidental Petroleum Corporation’s Current Report on Form 8-K filed with the SEC on May 10, 2019 (file no. 001-09210)).
