SEITEL ANNOUNCES SECOND QUARTER REVENUE AND CASH RESALES

Schedules Conference Call

HOUSTON, July 7, 2009 - Seitel, Inc., a leading provider of seismic data to the oil and gas industry, today announced that, based on preliminary information, total revenue for the quarter ended June 30, 2009, is expected to be $21.3 million, a 52% decrease from total revenue of $44.7 million for the same period last year.  Cash resales for the second quarter of 2009 were $7.2 million, down 78% from the same quarter of last year and down 28% on a sequential basis.  Seitel's cash resales reflected decreases throughout all of our geographical areas, with both large and small clients curtailing their expenditures on data from our library.  The absence of large licensing deals and the low number of library card contracts continue to hurt our licensing revenue.  Cash resales fell year-on-year by 79% and 74% in the U.S. and Canada, respectively.  For the six month period, Seitel's cash resales were $17.2 million, down $35.3 million or 67% as compared to 2008. 

We believe that the drop in our cash resales has been driven by weak prices for natural gas, further exacerbated by the economic uncertainty and tough credit markets that have triggered a sharp reduction in exploration spending in the U.S. and Canada.  North American drilling activity continued to fall during the second quarter, with the average year to date rig count dropping by 38% compared to the same period of last year.  Despite this sharp reduction in drilling activity, we believe that production of natural gas has not fallen significantly and continues to exceed current demand.  We have seen no indications at this point that our industry environment will improve materially in the near term or that our resales will increase.  Nonetheless, we expect that lower drilling activity will have an impact on natural gas production in the medium term, and that drilling and production costs in North America will continue to fall. The resulting tighter natural gas storage and improved returns for our customers should stimulate drilling activity and improve our licensing revenue to levels more in line with historical results.

On June 30, 2009, our cash balances stood at approximately $28.7 million.   The company is not in compliance with the covenants on its undrawn $25 million Wells Fargo Foothill credit facility.  We are still in discussions with our bank on the status of the credit facility.

The press release also includes the non-GAAP financial measure, cash resales, for which the most comparable GAAP measure is total revenue.

CASH RESALES

Cash resales represent licensing contracts from our seismic data library payable in cash. We believe this measure is helpful in determining the level of cash from operations available for cash operating expenses, debt service and unfunded capital expenditures. The following is a quantitative reconciliation of this non-GAAP financial measure to the most directly comparable GAAP financial measure, total revenue (in millions):

		Three Months Ended						Six Months Ended
		March 31,		June 30,		June 30,			June 30,		June 30,
		2009		2009 (a)		2008			2009 (a)		2008
Cash resales	$	10.0	$	7.2	$	32.7		$	17.2	$	52.5
Add other revenue components not included in cash resales:
Acquisition revenue		18.0		8.2		12.5			26.3		31.0
