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

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.
