The Company also drilled or participated in the drilling of two non- commercial wells, as follows:

      Lease Name/Well              Category           Working Interest %
    High Island 38 #2           Exploration/Deep Shelf        53%
    Ship Shoal 317 #1           Exploration/Shelf             75%

The Company also announced that it has sanctioned for development its Green Canyon Block 646 prospect ("Daniel Boone"). The discovery well was drilled in 2004 to a total measured depth of 12,365 feet. Daniel Boone is located approximately 119 miles off the coast of Louisiana in 4,230 feet of water. The discovery well encountered approximately 275 feet of high quality oil and natural gas-bearing sands. W&T intends to produce the well via a subsea production system tied back to the Front Runner spar, which is operated by Murphy Oil. W&T owns a 60% working interest in Daniel Boone and is the operator.

Tracy W. Krohn, Chairman and Chief Executive Officer, stated, "While I am pleased that we are twelve for fourteen so far this year for an 86% success rate, we are disappointed that we had two non-commercial wells. However, we remain encouraged and excited about our 2008 drilling program. Currently we have 9 rigs running and remain active. We recently brought on production at Ship Shoal 224 E-18, Ship Shoal 300 A-2ST and Ship Shoal 314 A-2ST and anticipate more throughout the year. Additionally, we have completed a well stimulation program on three wells at our Mahogany project. "

"We have also finalized our development plans for our Green Canyon 646 #1 discovery well on the Daniel Boone prospect. We believe the timing is excellent to commence the development of Daniel Boone and expect first production in second half 2009. It has taken a considerable amount of time to finalize the details of the project and locate the optimal facility to deliver the production. Development costs for Daniel Boone are included in our previously announced 2008 capital budget."
