                                     May 22, 2019

     Know all by these present, that I, Steven E. West, hereby constitute and
appoint each of Teresa L. Dick and P. Matt Zmigrosky as my true and lawful
attorneys-in-fact (each an "Attorney-in-Fact" and, collectively, the
"Attorneys-in-Fact"), each, individually or jointly, to:

     (1)     execute and deliver for and on behalf of me, in my capacity as one
             or more of an officer, director or significant stockholder of
             Rattler Midstream LP or any of its subsidiaries (collectively, the
             "Company"), Forms 3, 4 and 5 and any amendments thereto in
             accordance with Section 16(a) of the Securities Exchange Act of
             1934, as amended (the "Exchange Act") and the rules and regulations
             thereunder;

     (2)     do and perform any and all acts for and on behalf of me that 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 the same with the United States Securities and Exchange
             Commission (the "SEC") and any stock exchange or similar authority,
             and provide a copy as required by law or as either such Attorney-
             in-Fact deems advisable and appropriate, including, without
             limitation, the filing of a Form ID or any other documents
             necessary or appropriate to enable such documents to be filed
             electronically with the SEC; and

     (3)     take any other action of any type whatsoever in connection with the
             foregoing that, in the opinion of such Attorney-in-Fact, may be of
             benefit to, in the best interest of, or legally required by, or
             for, me, it being understood that the documents executed by such
             Attorney-in-Fact on behalf of me pursuant to this Limited Power of
             Attorney shall be in such form and shall contain such information
             and disclosures as such Attorney-in-Fact may approve in his or her
             sole discretion.

       I hereby grant to the Attorneys-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 I might or could do if
personally present, with full power of substitution, resubstitution or
revocation, and I hereby ratify and confirm all that the Attorneys-in-Fact, or
their substitute or substitutes, shall lawfully do or cause to be done by virtue
of this Limited Power of Attorney and the rights and powers granted herein.
I acknowledge that the Attorneys-in-Fact, in serving in such capacity at my
request, are not assuming, nor is the Company assuming, (i) any of my
responsibilities to comply with the requirements of the Exchange Act or the
Securities Act of 1933, as amended (the "Securities Act"), or any liability for
my failure to comply with such requirements, or (ii) any obligation or liability
I incur for profit disgorgement under Section 16(b) of the Exchange Act.  I
further acknowledge that this Limited Power of Attorney does not relieve me from
responsibility for compliance with my obligations under the Exchange Act or the
Securities Act.

       This Limited Power of Attorney shall remain in full force and effect
until I am no longer required to file Forms 3, 4 and 5 with respect to my
holdings of and transactions in securities issued by the Company, unless earlier
revoked by me in a signed writing delivered to the Attorneys-in-Fact.

     IN WITNESS WHEREOF, I have executed this Limited Power of Attorney as of
the date first written above.

                                              /s/ Steven E. West
