HOUSTON, Nov. 28, 2012

HOUSTON, Nov. 28, 2012 /PRNewswire/ --W&T Offshore, Inc. (NYSE: WTI) today
announced a discovery at the Big Bend exploration prospect in the deepwater
Gulf of Mexico. The well is located on Mississippi Canyon Block 698 in 7,200
feet of water and was drilled to a total depth of 15,989 feet. Open-hole
logging identified approximately 150 feet of net oil pay in two high-quality
Miocene reservoirs. W&T Offshore holds a 20% working interest in this well,
which is operated by Noble Energy, Inc. (NYSE: NBL).

Tracy W. Krohn, W&T Offshore's Chairman and Chief Executive Officer, stated,
"This well is an excellent oil discovery that should provide a very attractive
economic return on investment. It represents the type of deepwater Gulf of
Mexico project that we have increased our exposure to over the last few
years. The logging and pressure/volume/temperature data has confirmed Big
Bend's superb reservoir properties and fluid characteristics that are
indicative of many of the reservoirs in the deepwater Gulf of Mexico."

Offshore Update:
At our Mahogany field, Ship Shoal 349,we recently recompleted the SS 349 A2
well to a new pay zone which had not previously produced in the field. In
November, the completion achieved an initial production rate of 850 barrels of
oil and 1.1 MMcf per day of gas (1,000 barrels of oilequivalent per day),
which was well aboveexpectations. We have subsequently moved the rig to
conclude the drilling of the A9 ST-2development well to a new producing
location within the "P" sand. This well is part of our ongoing and highly
successful exploitation program for the field and is expected to provide
additional incremental production in the first quarter of 2013.

The West Cameron 73 #2 (30% WI; Walter operated) discovery well is currently
being completed in the deepest pay zone and is expected to be on production
during the third quarter of 2013. At our Matterhorn field, Mississippi Canyon
243,we have commenced operations to drill theA2 replacement well and expect
tohave that well completedearly in the first quarter of 2013. We are
currently drilling the Main Pass 108 B1 ST-2well, which will be the first of
a multi-well exploration program in and around our Main Pass area.

Onshore Operations
We completed 13 new wells in the Permian Basinat our Yellow Rose field
(Martin, Dawson, Gaines and Andrews counties) so far during the quarter,
bringing the total completed new well count to 59 year to date. During the
month of October, our Yellow Rose field grossproduction averaged
approximately 3,485 barrels (2,685barrels net) ofoil equivalent per day. In
November, we achieved a one dayrate of 4,069 barrels gross (3,133 barrels
net) of oil per day from the field. We are encouraged by the results to date
of our horizontal wells at our Yellow Rose field and expect more horizontal
wells to be part of our 2013 capital budget plans.

In Terry County in the Permian Basin, we have drilled and fracture treated the
Holmes 23-4 Unit 1-H, the first horizontal Wolfcamp well in our Terry County
area. The well is currently in the first few days of flowback. The
secondTerry County horizontal Wolfcampwell, the State Travis-Henson Unit
20#1-His currently drilling.

Outlook: The guidance for full year 2012 represents the Company's best
estimate of the range of likely future results, and is affected by the factors
described below in "Forward-Looking Statements."

Our prior guidance and revised guidance for the full yearis presented below.
Our revised productionguidance for the full year 2012reflectsthe effect of
production deferrals resulting from multiplethird-party pipeline outages,
production delays and lower NGL production across the system. We expect our
production rate at the end of 2012 to beapproximately 50,000 Boe per day, or
300 MMcfe per day.
