Known by all these present, that the undersigned hereby constitutes and appoints
each of Kevin McDonald, Valorie Wanner and Safieh Hill, signing severally and
not jointly, with full power of substitution, the undersigned's true and lawful
attorney-in-fact (herein so called) to:

        1.  prepare, execute in the undersigned's name and on the undersigned's
        behalf, and submit to the United States Securities and Exchange
        Commission (the  "SEC") a Form ID, Uniform Application for Access Codes
        to File on EDGAR and any other documents necessary or appropriate to
        obtain or maintain codes and passwords enabling the undersigned to make
        electronic filings with the SEC of reports required by Section 16(a) of
        the Securities Exchange Act of 1934, as amended, and the rules
        thereunder (collectively, the "Exchange Act"), or any other rule or
        regulation of the SEC;

        2.  execute for and on behalf of the undersigned (a) Forms 3, 4 and 5
        (including amendments thereto) in accordance with Section 16(a) of the
        Exchange Act, (b) Form 144 and (c) Schedules 13D and 13G (including
        amendments thereto) in accordance with Sections 13(d) and 13(g) of the
        Exchange Act, but only to the extent each such form or schedule relates
        to the undersigned's beneficial ownership of securities of NexTier
        Oilfield Solutions Inc. or any of its affiliates, subsidiaries or
        successors (collectively, "NexTier");

        3.  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 such Form
        3, 4 or 5, Form 144 or Schedule 13D or 13G (including amendments
        thereto) and timely file such Forms or Schedules with the SEC and any
        stock exchange, 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

        4.  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 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 such form and shall contain such terms and
        conditions as the attorney-in-fact may approve in the attorney-in-fact's
        discretion.

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

     The undersigned hereby agrees that each such 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 NexTier and each such 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 such attorney-in-fact for purposes of executing,
acknowledging, delivering or filing Forms 3, 4 or 5, Form 144 or Schedule 13D or
13G (including amendments thereto) and agrees to reimburse NexTier and such
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 Forms 3, 4 and 5, Form 144 and
Schedules 13D and 13G (including amendments thereto) with respect to the
undersigned's holdings of and transactions in securities issued by NexTier,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact. This Power of Attorney revokes all other powers of
attorney that the undersigned has previously granted concerning the matters
described herein.

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