UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The following unaudited pro forma condensed consolidated balance sheet of W&T Offshore, Inc. (the “Company,” “we” or “our”) as of March 31, 2007 illustrates the pro forma effect on the Company’s historical financial position of the issuance of the Company’s $450 million 8 1/4% Senior Notes due 2014 (the “Notes”). The unaudited pro forma condensed consolidated statement of income of the Company for the three months ended March 31, 2007 illustrates the pro forma effect on the Company’s results of operations of the issuance in June 2007 of the Notes. The unaudited pro forma condensed consolidated balance sheet as of March 31, 2007 was prepared assuming that the issuance of the Notes had occurred on March 31, 2007. The unaudited pro forma condensed consolidated statement of income for the three months ended March 31, 2007 was prepared assuming that the Notes were issued and proceeds applied on January 1, 2007.

The unaudited adjustments that are described in the accompanying notes and the resulting unaudited pro forma condensed consolidated financial information are based on available information and certain assumptions we believe are reasonable in connection with the transaction as described above. In our opinion, all adjustments that are necessary to present fairly the pro forma information have been made. The unaudited pro forma condensed consolidated financial information does not purport to represent what the Company’s financial position or results of operations would have been had the transaction occurred on the dates indicated or the financial position or results of operations for any future date or period.

The unaudited pro forma condensed consolidated financial information and accompanying notes should be read in conjunction with the historical financial statements and the accompanying notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which are set forth in our annual report on Form 10-K for the year ended December 31, 2006 and the quarterly report on Form 10-Q for the quarter ended March 31, 2007.
