LIMITED POWER OF ATTORNEY FOR
SECTION 16 REPORTING OBLIGATIONS

    Know all by these presents, that the undersigned, David L. Treadwell (the
"Reporting Person"), hereby constitutes and appoints each of Kyle O'Neill and
Erin C. Simonson as the Reporting Person's true and lawful attorney-in-fact to:

    (1) prepare, execute in the Reporting Person's name and on the Reporting
Person's behalf, and submit to the United States Securities and Exchange
Commission (the "SEC") a Form ID, including amendments thereto, and any other
documents necessary or appropriate to obtain codes, passwords, and passphrases
enabling the Reporting Person 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 U.S. Well Services, Inc. (the
"Company"), Forms 3, 4 and 5 in accordance with Section 16(a) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), 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,
and 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 hereby grants to each 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,
or such attorney-in-fact's substitute or substitutes, shall lawfully do or cause
to be done by the virtue of this power of attorney and the rights and powers
herein granted. The Reporting Person acknowledges that the foregoing attorneys-
in-fact, in serving in such capacity at the request of the Reporting Person, are
not assuming, nor is the Company assuming, any of the Reporting Person's
responsibilities to comply with Section 16 of the Exchange Act.

    This Power of Attorney shall remain in full force and 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 foregoing attorney-in-fact.

    IN WITNESS WHEREOF, the Reporting Person has caused this Power of Attorney
to be executed as of this 20th day of March, 2020.
