W&T Offshore Provides Operational Update and Drilling Successes

HOUSTON, Oct. 17 /PRNewswire-FirstCall/ -- W&T Offshore, Inc. (NYSE: WTI) today announced it is currently producing approximately 96 million cubic feet of gas equivalent (MMcfe) net per day, which represents 51% of the Company's pre-Hurricane Rita and 39% pre-Hurricane Katrina production. The Company also reports that it has been successful with its exploration and development drilling program that includes eight successful wells out of nine wells drilled since the end of the second quarter, six of which were drilled since Hurricane Katrina.

The Company's production is back online in part due to the repairs and availability of third party infrastructure, and processing plant repairs, some of which occurred earlier than anticipated. W&T expects additional production to return online over the next several weeks, as further field repairs are completed and third party processing plants and pipelines are brought back online. The Company still estimates that approximately 55 MMcfe per day of its net production is shut-in because of Hurricane Katrina. W&T's pre-Hurricane Katrina and Rita volumes were approximately 245 MMcfe net per day. Based on estimates for deferred production due to the hurricanes, W&T expects third quarter net production to range between 16.3 and 18.0 billion cubic feet of gas equivalent (Bcfe), or between 179 and 197 MMcfe per day.

Tracy W. Krohn, Chairman and Chief Executive Officer, stated, "The outstanding coordinated efforts between W&T personnel and our various service providers demonstrates what empowered employees can achieve when given a difficult task. Among other activities resulting in increased production, the team coordinated the rerouting of products around a temporarily shut-down processing facility south of Lafayette, Louisiana, to an alternative facility, thereby facilitating the resumption of approximately 40 MMcfe of net daily production. We are focused on developing additional solutions that will further enhance our ability to produce volumes shut-in by the recent storms."

    W&T also continues to have success with its exploration and development
program.  Since the end of the second quarter, the Company successfully
drilled four exploration wells and four development wells, with one
unsuccessful development well.  This includes five successful wells since
Hurricane Katrina.
