HOUSTON, Dec. 6, 2013 /PRNewswire/ -- W&T Offshore, Inc. (NYSE: WTI) today
announced a sub-salt oil discovery at the "Dantzler" exploration prospect in
the Deepwater Gulf of Mexico. The well is located on Mississippi Canyon block
782 in 6,580 feet of water and was drilled to a total depth of 19,234 feet.
Wireline logging data indicates approximately 120 feet of net pay in two
high-quality Miocene reservoirs which are primarily crude oil. W&T Offshore
holds a 20% working interest in this well, which is operated by Noble Energy,
Inc.

The Dantzler discovery is located roughly 12 miles west of W&T's previous
discoveries at Big Bend and Troubadour in the Mississippi Canyon 698 and 699
blocks. The operator has provided discovered gross resource^(1) estimates at
Dantzler of between 55 and 95 million barrels of oil equivalent.

Tracy W. Krohn, W&T Offshore's Chairman and Chief Executive Officer, stated,
"The discovery at Dantzler continues our string of successful deepwater
exploration projects and provides us with another impact discovery to grow
both our reserves and production in the Gulf of Mexico."

(1) Range of resource estimate based on 75th and 25th percentile
probabilities.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. These forward-looking statements reflect our current
views with respect to future events, based on what we believe are reasonable
assumptions. No assurance can be given, however, that these events will occur.
These statements are subject to risks and uncertainties that could cause
actual results to differ materially including, among other things, market
conditions, oil and gas price volatility, uncertainties inherent in oil and
gas production operations and estimating reserves, unexpected future capital
expenditures, competition, the success of our risk management activities,
governmental regulations, uncertainties and other factors discussed in W&T

The Securities and Exchange Commission requires oil and gas companies, in
their filings with the SEC, to disclose proved reserves that a company has
demonstrated by actual production or conclusive formation tests to be
economically and legally producible under existing economic and operating
conditions. The SEC permits the optional disclosure of probable and possible
reserves, however, we have not disclosed the Company's probable and possible
reserves in our filings with the SEC. We use certain terms in this news
release, such as "gross resources." This estimate is by its nature more
speculative than estimates of proved, probable and possible reserves and
accordingly are subject to substantially greater risk of being actually
realized. The SEC guidelines strictly prohibit us from including these
estimates in filings with the SEC. Investors are urged to consider closely the
disclosures and risk factors in our most recent annual report on Form 10-K and
in other reports on file with the SEC, available from our website at
www.wtoffshore.com.
