REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Shareholders of
Carrizo Oil & Gas, Inc.

We have audited the accompanying consolidated balance sheet of Carrizo Oil & Gas, Inc. as of December 31, 2003 and 2002, and the related consolidated statements of operations, shareholders' equity and cash flows for each of the two years in the period ended December 31, 2003. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit. The consolidated financial statements of Carrizo Oil & Gas, Inc. as of December 31, 2001 and for the year then ended, were audited by other auditors who have ceased operations and whose report dated March 20, 2002, expressed an unqualified opinion on those statements, before the revisions described in Note 2.

We conducted our audit in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company at December 31, 2003 and 2002, and the consolidated results of its operations and its cash flows for the two years then ended, in conformity with accounting principles generally accepted in the United States.

As described in Note 2, the Company revised the reported amount of the after-tax write-down that would have been taken as of December 31, 2001 using prices in effect at that date. We audited the adjustments describe in Note 2 that were applied to revise the reported amount of the full cost ceiling test write-down had the Company not utilized the improvements in pricing subsequent to December 31, 2001 and/or the addition of proved oil and natural gas reserves on existing properties subsequent to the end of the period but prior to issuance of financial statements. Our procedures included (a) agreeing the revised tax basis in the full cost ceiling test computation to the Company's underlying records obtained from management, and (b) testing the mathematical accuracy of the revisions to the full cost ceiling computation. In our opinion such adjustments are appropriate and have been properly applied. However, we were not engaged to audit, review, or apply any procedures to the 2001 consolidated financial statements of the Company other than with respect to such adjustments and accordingly, we do not express an opinion or any other form of assurance on the 2001 consolidated financial statements taken as a whole.

As discussed in Note 2 to the consolidated financial statements, effective January 1, 2003, the Company changed its method of accounting for asset retirement obligations.
