Know all by these present, that the undersigned hereby constitutes and appoints
each of Bass C. Wallace, Jr. and Kimberly M. O'Brien, signing singly, and with
full power of substitution, as the undersigned's true and lawful
attorney-in-fact to:

1. execute for and on behalf of the undersigned, in the undersigned?s capacity
as an officer and/or director of TETRA Technologies, Inc. (the "Company") Form
ID and Forms 3, 4, and 5 (including amendments thereto) in accordance with
Section 16(a) of the Securities Exchange Act of 1934 and the rules thereunder;

2. do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete and execute any such Form ID, 3, 4,
or 5, complete and execute any amendment or amendments thereto, and timely file
such form with the United States Securities and Exchange Commission and any
stock exchange, self-regulatory association or any other authority, and
provide a copy as required by law or as advisable to such persons as the
attorney-in-fact deems appropriate; and

3. take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of each such attorney-in-fact, may be of
benefit to, in the best interest of, or legally required by, the undersigned,
it being understood that the documents executed by such 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 such attorney-in-fact may
approve in such attorney-in-fact's discretion.

The undersigned 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 undersigned
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 virtue of this power of attorney and the rights and powers
herein granted. The undersigned acknowledges that the forgoing
attorneys-in-fact, in serving in such capacity at the request of the
undersigned, are not assuming, nor is the Company assuming, any of the
undersigned's responsibilities to comply with Section 16 of the Securities
Exchange Act of 1934.

The undersigned further 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 the Company 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 Form 3, 4 or 5
(including amendments thereto).

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
(including amendments thereto) with respect to the undersigned's holdings of
and transactions in securities issued by the Company, 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 this 8th day of August, 2017.
