        Know all by these presents, I hereby appoint Thomas F. Getten, Reid Lea
and Michael T. Larkin or any one of them acting alone, to act as my agent and
attorney-in-fact for the purpose of completing, executing and filing on my
behalf with the Securities and Exchange Commission, the New York Stock Exchange,
Inc. or any other exchange or self regulatory body, any Form 3 "Initial
Statement of Beneficial Ownership of Securities", Form 4 "Statement of Changes
in Beneficial Ownership of Securities", Form 5 "Annual Statement of Beneficial
Ownership of Securities," or any other similar form to report securities
ownership that may, in the opinion of any of them be necessary, with respect to
any transaction in securities of W&T Offshore, Inc.

Nothing herein shall relieve me of the responsibility for the accuracy of the
information and representations contained in any Form 3, Form 4, Form 5, or
other similar form completed, executed and filed pursuant to this power of
attorney.

This power of attorney shall supersede all similar prior powers of attorney and
will remain effective as to the agents and attorneys-in-fact referred to above

similar form completed, executed and filed pursuant to this power of attorney.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed on this 28th day of April, 2009.
