The undersigned hereby constitutes and appoints Ryan Dalton and Colin

substitution, as the undersigned's true and lawful attorney-in-fact to:

     1.   execute for and on behalf of the undersigned any Form 3, Form 4, Form
          5 and Form 144 (including any amendments, corrections, supplements or
          other changes thereto) in accordance with Section 16(a) of the
          Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
          the rules thereunder, but only to the extent each form or schedule
          relates to the undersigned's beneficial ownership of securities of
          Parsley Energy, Inc. or any of its subsidiaries;

     2.   do and perform any and all acts for and on behalf of the undersigned
          that may be necessary or desirable to complete and execute any Form 3,
          Form 4, Form 5 or Form 144 (including any amendments, corrections,
          supplements or other changes thereto) and timely file the forms or
          schedules with the Securities and Exchange Commission and any stock
          exchange or quotation system, self-regulatory association or any other
          authority, and provide a copy as required by law or advisable to such
          persons as the attorney-in-fact deems appropriate; and

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

The undersigned hereby grants to the attorney-in-fact full power and
authority to do and perform all and every act 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 undersigned might or could do if personally
present, with full power of substitution or revocation, hereby ratifying and
confirming all that the attorney-in-fact shall lawfully do or cause to be done
by virtue of this Power of Attorney and the rights and powers granted herein.
The undersigned acknowledges that the attorneys-in-fact, in serving in such
capacity at the request of the undersigned, are not assuming (nor is Parsley
Energy, Inc. assuming) any of the undersigned's responsibilities to comply with
Section 16 of the Exchange Act.

The undersigned agrees that the attorney-in-fact may rely entirely on
information furnished orally or in writing by or at the direction of the
undersigned to the attorney-in-fact. The undersigned also agrees to indemnify
and hold harmless Parsley Energy, Inc. and the attorney-in-fact against any
losses, claims, damages or liabilities (or actions in these respects) that arise
out of or are based upon any untrue statements or omissions of necessary facts
in the information provided by or at the direction of the undersigned, or upon
the lack of timeliness in the delivery of information by or at the direction of
the undersigned, to the attorney-in fact for purposes of executing,
acknowledging, delivering or filing a Form 3, Form 4, Form 5 or Form 144
(including any amendments, corrections, supplements or other changes thereto)
with respect to the undersigned's holdings of and transactions in securities
issued by Parsley Energy, Inc., and agrees to reimburse Parsley Energy, Inc. and
the attorney-in-fact on demand for any legal or other expenses reasonably
incurred in connection with investigating or defending against any such loss,
claim, damage, liability or action.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Form 3, Form 4, Form 5 and Form 144
(including any amendments, corrections, supplements or other changes thereto)
with respect to the undersigned's holdings of and transactions in securities
issued by Parsley Energy, Inc., unless earlier revoked by the undersigned in a
signed writing delivered to the attorney-in-fact. This Power of Attorney does
not revoke any other power of attorney that the undersigned has previously
granted.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of the date written below.
