W&T OFFSHORE ANNOUNCES PERMIAN BASIN ACQUISITION

HOUSTON — April 26, 2011 — W&T Offshore, Inc. (NYSE: WTI) today announced that it has entered into a purchase and sale agreement with private sellers to acquire approximately 21,900 gross leasehold acres (21,500 net acres) in the West Texas Permian Basin for a purchase price of $366 million, subject to adjustments and an effective date of January 1, 2011. The reserves are over 91% oil and natural gas liquids. At January 1, 2011, estimates of proved reserves to be acquired are approximately 27 million barrel equivalents (164 Bcfe); and, estimates of proved and probable reserves to be acquired are approximately 53 million barrel equivalents (318 Bcfe) (both using a 6 to 1 Mcf to barrel equivalency). The current wells produce around 2,800 barrel equivalents per day. Since the effective date of the proposed acquisition, production has increased from about 1,900 barrel equivalents. The sellers have three active rigs drilling in the field and ongoing completions are being made on the new wells. We expect to keep at least three rigs working in the field throughout the remainder of 2011. Accordingly, we would expect daily production to increase.

There is significant upside potential in the acquisition with hundreds of proved undeveloped and probable well locations. Capital expenditures associated with planned development activities for these properties for the rest of 2011 are currently estimated at $35 to $40 million. The closing, which is subject to customary closing conditions and normal closing price adjustments, including effective date adjustments, is anticipated in the second quarter and will be funded from cash on hand and borrowings under our revolving bank credit facility.

Tracy W. Krohn, Chairman and Chief Executive Officer, commented, “The acquisition of the Permian Basin oil properties will allow us to continue with our goals of a steadier growth pattern coupled with good cash flow and positive full cycle economics. We believe that there are many more attractive acquisition opportunities for us both onshore and offshore.”
