The undersigned (the "Reporting Person") hereby constitutes and
appoints Mark A. Erickson, Russell T. Kelley, Jr., Eric J. Christ and
Tom L. Brock and each of them, as the Reporting Person's true and
lawful attorney-in-fact to:

(1)  prepare, execute in the undersigned's name and on the

Commission (the "SEC") a Form ID, including amendments thereto, and any

enabling the undersigned to make electronic filings with the SEC of
reports required by Section 16(a) of the Securities Exchange Act of
1934 or any rule or regulation of the SEC;

(2)  execute for and on behalf of the Reporting Person, in the
Reporting Person's capacity as an officer or director of Extraction Oil
& Gas, Inc. (the "Company"), Forms 3, 4 and 5 in accordance with
Section 16(a) of the Securities Exchange Act of 1934 and the rules
thereunder;

(3)  do and perform any and all acts for and on behalf of the Reporting
Person which may be necessary or desirable to complete and execute any
such Form 3, 4 or 5, complete and execute any amendment or amendments
thereto, and timely file such form with the SEC and any stock exchange
or similar authority; and

(4)  take any other action of any type whatsoever in connection with
the foregoing which, in the opinion of such attorney-in-fact, may be of
benefit to, in the best interest of, or legally required by, the
Reporting Person, it being understood that the documents executed by
such attorney-in-fact on behalf of the Reporting Person pursuant to
this Power of Attorney shall be in such form and shall contain such
terms and conditions as such attorney-in-fact may approve in such
attorney-in-fact's discretion.

The Reporting Person grants to such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever
requisite, necessary, or proper to be done in the exercise of any of
the rights and powers herein granted, as fully to all intents and
purposes as the Reporting Person might or could do if personally
present, with full power of substitution or revocation, hereby
ratifying and confirming all that such attorney-in-fact shall lawfully
do or cause to be done by virtue of this Power of Attorney and the
rights and powers herein granted.  The Reporting Person acknowledges
that the foregoing attorney-in-fact, in serving in such capacity at the
request of the Reporting Person, is not assuming, nor is the Company
assuming, any of the Reporting Person's responsibilities to comply with
Section 16 of the Securities Exchange Act of 1934.

This Power of Attorney shall remain in effect until the Reporting
Person is no longer required to file Forms 3, 4 and 5 with respect to
the Reporting Person's holdings of, and transactions in securities
issued by, the Company, unless earlier revoked by the Reporting Person
in a signed writing delivered to the attorney-in-fact.



IN WITNESS WHEREOF, the Reporting Person has caused this Power of
Attorney to be executed on February 17, 2017.
