HOUSTON, July 13, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- W&T Offshore, Inc. (NYSE: WTI) has updated second quarter and full-year 2007 production guidance.

Updated Second Quarter and Full Year 2007 Production Guidance


    W&T is revising its second quarter and full-year 2007 production guidance,
as follows:


                           Revised      Prior
                           Second      Second       Revised         Prior
    Estimated Production   Quarter     Quarter     Full-Year      Full-Year
                            2007        2007         2007           2007

    Crude oil (MMBbls)   2.05 - 2.15  2.1 - 2.2    7.7 - 8.0      8.1 - 8.5

    Natural gas (Bcf)    18.2 - 18.6 20.0 - 21.0  74.7 - 78.7    84.1 - 88.7

    Total (Bcfe)         30.5 - 31.5 32.7 - 34.4 121.0 - 127.0  132.7 - 140.0

Significant contributors to the revision in guidance for the second quarter and full-year 2007 are:

    -- Mississippi Canyon 718 "Pluto" -- Life of current reservoir extended
       from June to November deferring rate increase from recompletion.
    -- Main Pass 163/185 -- One-month project start up delay.
    -- Ewing Bank 989 "Cypress" -- Production performance less than forecast,
       completion sanded up on June 25.  Recompletion plans in progress.
    -- Eugene Island 205 C-4ST -- Completion watered out earlier than
       expected.


From the above-mentioned items, total production impact for the second quarter 2007 is a reduction of approximately 2 Bcfe.

Tracy W. Krohn, Chairman and Chief Executive Officer stated, "The Company has had unanticipated production deferral at Mississippi Canyon 718 'Pluto,' other wells produced at rates less than anticipated and we experienced a completion failure at Ewing Bank 989 'Cypress.' Accordingly, the Company is revising both second quarter and full-year guidance downward." Mr. Krohn continued, "Despite the lower production, our realized oil and gas prices were higher than we expected during the second quarter and as a result, the Company will exceed the First Call analysts' consensus estimates, which average $0.44 per share for the second quarter."
