Updated Third Quarter and Full-Year 2006 Guidance

W&T is revising its third quarter and full year 2006 estimated guidance to reflect the Kerr-McGee transaction. Currently, we anticipate an 18 percent increase in third quarter production and a 16 percent increase for the full year 2006 over our stand-alone guidance. Approximately 2.8 Bcfe has been deferred resulting from third party pipeline repair delays, primarily at East Cameron 321 and Mississippi Canyon 718. The guidance assumes incremental production and expenses as of September 1, 2006.
