W&T Offshore Completes Permian Basin Acquisition

HOUSTON, May 11, 2011 /PRNewswire via COMTEX/ --

W&T Offshore, Inc. (NYSE: WTI) today announced that it has completed the purchase of approximately 21,900 gross leasehold acres (21,500 net acres) in the West Texas Permian Basin from private sellers, with an effective date of January 1, 2011. The announced purchase price of $366 million is subject to customary post-effective adjustments.

At January 1, 2011, estimates of the acquired proved reserves were approximately 27 million barrel equivalents (164 Bcfe) and estimates of probable reserves were approximately 26 million barrel equivalents (154 Bcfe) (both using a 6 to 1 Mcf to barrel equivalency). The proved reserves are approximately 91% oil and natural gas liquids.

Tracy W. Krohn, Chairman and Chief Executive Officer, commented, "Through this Permian Basin oil property acquisition, combined with 9,400 net exploratory acres we recently acquired in the basin, we now have a new focus area that offers the potential for substantial longterm growth and attractive full-cycle economic returns. Additionally, the oil and liquids component of our total estimated proved reserves as of December 31, 2010 increases from 47% to 58%. Currently, the acreage acquired from this acquisition has approximately 73 wells producing about 2950 barrel of oil equivalent per day and hundreds of proved undeveloped and probable well locations that have been identified. For the balance of 2011, we have allocated between $35 million and $40 million in capital expenditures associated with planned development and expect to maintain an active drilling program with at least three rigs working in West Texas. This budgeted amount is within our total 2011 capital plan of $310 million that we announced previously. Initially we will be targeting the Spraberry, Dean, Wolfcamp and Strawn formations in the Wolfberry trend, but we believe there may be potential for production from deeper formations as well."
