W&T Offshore Confirms 2005 Guidance



W&T Offshore announced that it has confirmed fourth quarter 2005 guidance. In addition, the independent oil and natural gas company updated first quarter 2006 production guidance to reflect delays in certain pipeline, sales system, and other infrastructure repairs related to Hurricanes Katrina and Rita; the availability of certain equipment; and other operational issues. The company notes that the guidance is for stand-alone W&T and does not include the effect of the recently announced transaction with Kerr-McGee, which is expected to close during the second quarter.

Fourth Quarter 2005 Production Guidance Confirmation

W&T expects to report that production for the fourth quarter of 2005 exceeded the previously announced guidance range of 11.7 to 12.3 billion cubic feet of natural gas equivalent (Bcfe). The Company also reports that it expects operating expense to be in line with or lower than the previously announced guidance ranges.

    Updated First Quarter 2006 and Full Year 2006 Production Guidance
    W&T is revising its first quarter production guidance, as follows:

                              Revised First   Prior First     Estimate for
    Estimated Production       Quarter 2006   Quarter 2006     Full-Year
                                                                  2006
    Crude oil (MMBbls)           1.0 - 1.1     1.1 - 1.2       5.8 - 6.1

    Total (Bcfe)                15.9 - 16.3   17.2 - 18.3     83.0 - 87.7

Primary contributors to the revision in guidance for the first quarter 2006 are:

    *  South Timbalier 229 - Platform downtime due to longer than expected use
       of a rig used to drill a successful exploration well and related
       compressor downtime.  Approximately 0.4 Bcfe net expected to be
       deferred during the first quarter.
    *  Main Pass 69 - Delay in pipeline repair.  Approximately 0.3 Bcfe net
       expected to be deferred during the first quarter.
    *  Green Canyon 178 (Baccarat) - Electrical failure in subsea umbilical.
       Approximately 0.3 Bcfe net expected to be deferred during the first
       quarter.
    *  Ship Shoal 222 - Delay in sales system repair.  Approximately 0.2 Bcfe
       net expected to be deferred during the first quarter.
    *  Eugene Island 205 - Delay in rig availability due to success at Ship
       Shoal 149.  Approximately 0.2 Bcfe net expected to be deferred during
       the first quarter.
    *  East Cameron 321 - Delay in sales system repair.  Approximately 0.2
       Bcfe net expected to be deferred during the first quarter.

    Full-year 2006 production guidance is not being revised.
    W&T also confirms that first quarter 2006 and full year 2006 operating
expense guidance is unchanged from previously announced guidance.  See table

"We are pleased to be able to confirm that our fourth quarter 2005 performance was in line with or better than our guidance for that period," said Tracy W. Krohn, Chairman and Chief Executive Officer. "We of course were hopeful that more progress would have been made during the first quarter with respect to certain properties, but would emphasize that our updated guidance primarily reflects a deferral of production, not a loss of reserves. Because others operate some of these properties or pipelines, we do not control the timing of all of the repairs. We will continue to work to expedite repairs to those properties we do operate, and encourage our third-party operators to do the same," Mr. Krohn continued.
