This Amendment No. 3 to Schedule 13D (this “Amendment No. 3”) relates to the beneficial ownership by the Reporting Persons of the common units representing limited partner interests (the “Common Units”) of Noble Midstream Partners LP, a Delaware limited partnership (the “Issuer”) and amends and supplements the initial statement on Schedule 13D filed by the Reporting Persons with the Securities and Exchange Commission (the “SEC”) on October 5, 2020, the Amendment No. 1 to Schedule 13D filed by the Reporting Persons with the SEC on February 5, 2021 and the Amendment No. 2 to Schedule 13D filed by the Reporting Persons with the SEC on March 5, 2021 (as amended to date, the “Schedule 13D”). This Amendment No. 3 is being filed by the Reporting Persons pursuant to the Joint Filing Statement. Capitalized terms used but not otherwise defined in this Amendment No. 3 shall have the same meanings ascribed to them in the Schedule 13D. Except as specifically provided herein, this Amendment No. 3 does not modify any of the information previously reported in the Schedule 13D.

Item 2. Identity and Background

Item 2 is hereby amended and restated as follows:

(a) The reporting persons are (i) Chevron Corporation, a Delaware corporation (“Chevron”), (ii) Noble Energy, Inc., a Delaware corporation, (iii) NBL Midstream, LLC, a Delaware limited liability company (“NBL Midstream”) and (iv) Cadmium Holdings Inc., a Delaware corporation (“Holdings” and, together with Chevron, Noble and NBL Midstream, the “Reporting Persons”).

NBL Midstream is a wholly-owned subsidiary of Noble and owner of all the membership interests of the General Partner, which is the non-economic general partner of the Issuer. NBL Midstream holds 56,447,616 common units (“Common Units”) representing approximately 62.6% of the Issuer’s limited partner interests. Holdings is a wholly-owned subsidiary of Chevron. As a result of the Merger, Holdings holds 33,779,412 Common Units representing approximately 37.4% of the Issuer’s limited partner interests. Accordingly, the Reporting Persons are hereby filing a joint Schedule 13D.

All disclosures herein with respect to any Reporting Person are made only by such Reporting Person. Any disclosure herein with respect to persons other than the Reporting Persons are made on information and belief after making inquiry to the appropriate party.

(b) (i) The business address of each of Chevron and Holdings is 6001 Bollinger Canyon Road, San Ramon, California 94583-2324. (ii) The business address of Noble is 1001 Noble Energy Way, Houston, Texas 77070. (iii) The business address of NBL Midstream is 1001 Noble Energy Way, Houston, Texas 77070.

(c) Chevron manages its investments in subsidiaries and affiliates and provides administrative, financial, management and technology support to U.S. and international subsidiaries that engage in integrated energy and chemicals operations. Upstream operations consist primarily of exploring for, developing and producing crude oil and natural gas; processing, liquefaction, transportation and regasification associated with liquefied natural gas; transporting crude oil by major international oil export pipelines; transporting, storage and marketing of natural gas; and a gas-to-liquids plant. Downstream operations consist primarily of refining crude oil into petroleum products; marketing of crude oil and refined products; transporting crude oil and refined products by pipeline, marine vessel, motor equipment and rail car; and manufacturing and marketing of commodity petrochemicals, plastics for industrial uses and fuel and lubricant additives. Noble and NBL Midstream are engaged in the energy business. Holdings was formed in connection with the Merger and its sole business is to hold Common Units.

(d) - (e) During the past five years, none of the Reporting Persons have (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) nor (ii) been 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.

(f) Not applicable.

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 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.

Item 3 of the Schedule 13D is hereby amended and supplemented as follows:

The total consideration paid for the Common Units in connection with the Merger was valued at approximately $515,578,567 (based on the closing price of Chevron Common Stock on May 10, 2021) and consisted of the issuance of shares of Chevron Common Stock in exchange for all of the issued and outstanding publicly held Common Units. Each issued and outstanding publicly held Common Unit was converted into the right to receive 0.1393 shares of Chevron Common Stock.

Item 4. Purpose of the Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

On May 11, 2021, pursuant to the terms and conditions of the Merger Agreement, Merger Sub merged with and into the Issuer, with the Issuer continuing and surviving as an indirect, wholly-owned subsidiary of Chevron. Pursuant to the terms of the Merger Agreement, each publicly held Common Unit was converted into the right to receive 0.1393 shares of Chevron Common Stock.

As a result of the Merger, the Reporting Persons collectively are the beneficial owners of all of the Common Units of the Issuer.

Following the consummation of the transactions contemplated by the Merger Agreement, the Issuer’s Common Units ceased to be listed on the Nasdaq Global Select Market (“Nasdaq”), and the Issuer will request that Nasdaq file with the SEC a Form 25 notification of Removal from Listing and/or Registration to delist and deregister the Common Units under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Issuer intends to file a certification on Form 15 under the Exchange Act with the SEC requesting the deregistration of its Common Units under Section 12(g) of the Exchange Act and the suspension of its reporting obligations under Sections 13 and 15(d) of the Exchange Act.

Item 5. Interest in the Securities of the Issuer.

(a) See rows (11) and (13) of the cover pages to this Amendment No. 3 for the aggregate number of Common Units and percentages of Common Units beneficially owned by each of the Reporting Persons, which information is incorporated herein by reference.

(b) See rows (7) through (10) of the cover pages to this Amendment No. 3 for the number of Common Units as to which each Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition, which information is incorporated herein by reference.

(c) Other than as described in Item 3 and Item 4, during the past 60 days none of the Reporting Persons or the Listed Persons has effected any transactions in the Common Units.

(d) None.

(e) Not applicable.
