For Immediate Release

TETRA TECHNOLOGIES, INC.

REPORTS FIRST QUARTER 2008 RESULTS

May 12, 2008 (The Woodlands, Texas), TETRA Technologies, Inc. (TETRA or the Company) (NYSE:TTI) today announced first quarter 2008 results of $0.10 per share. The $0.10 per share compares to $0.27 per share reported in the first quarter of 2007. The 2008 first quarter earnings are consistent with and slightly above the estimated earnings reflected in the directional earnings guidance graph included in the April 7 press release, for all business segments. All financial data in the text portion of this release are before discontinued operations, and all per share amounts are fully diluted.

Consolidated revenues for the quarter ended March 31, 2008 were $225,156,000 versus $243,596,000 in the first quarter of 2007. Total gross profit was $42,047,000 in the first quarter of 2008 versus $57,465,000 in the first quarter of 2007. Income before discontinued operations was $7,354,000 in the first quarter of 2008 and $20,347,000 in the comparable period of 2007. Net income was $6,687,000 in 2008’s first quarter versus $20,662,000 in 2007’s first quarter.

Consolidated results per share from continuing operations for the first quarter of 2008 were earnings of $0.10 with 75,463,000 weighted average diluted common shares outstanding versus $0.27 with 75,091,000 weighted average diluted common shares outstanding in the first quarter of 2007.

Divisional pretax earnings from continuing operations in the first quarter of 2008 versus the first quarter of 2007 were: Fluids Division – $6,841,000 in 1Q 2008 and $7,947,000 in 1Q 2007; Well Abandonment & Decommissioning Services (WA&D Services) – a loss of $4,103,000 in 1Q 2008 and earnings of $11,041,000 in 1Q 2007; Maritech – $7,374,000 in 1Q 2008 and $11,128,000 in 1Q 2007; and, Production Enhancement Division – $15,372,000 in 1Q 2008 and $11,458,000 in 1Q 2007.

Financial data relating to net income, as well as discontinued operations, are available in the accompanying financial table in this press release.

Geoffrey M. Hertel, President and Chief Executive Officer, stated, “Our aggregate first quarter earnings would have been in line with our original earnings guidance range, if not for the effects of the weather related shortfall in Well Abandonment & Decommissioning (WA&D) Services. In the seasonally weak first quarter, any weather problems can turn a modest profit into a modest loss in WA&D Services. This happened in 2008’s first quarter, and as a result, our first quarter earnings were approximately $0.07 less than what we planned in our original guidance range. We previously disclosed that weather had negatively affected our WA&D Services during the first quarter on April 7, when we modified our segment guidance. The actual earnings for all business areas, including WA&D Services, were slightly better than those reflected in the directional earnings guidance graph included in the April 7 press release.

“First quarter results were not expected to make or break our earnings for the entire 2008 fiscal year. However, the final three quarters of 2008 are each very important. Dramatic sequential improvement is expected to begin in the current, second quarter. Drivers for this anticipated improvement include: in WA&D Services, expected increases in activity, particularly in heavy-lift and diving; in Maritech, increasing production and projected higher prices; in Fluids, the seasonal impact of TCE; and, in Production Enhancement, expected increasing activity in testing. It should be noted that we are not allowed to project any estimates for Compressco.

“We are all aware that over the last nine months, TETRA has had to overcome a number of obstacles, including: dramatically reduced earnings in Fluids, primarily due to a contract termination and lack of inventory gains which occurred in 2006; a $20 million annualized earnings drop in Maritech associated with differing hedge prices in 2006 and 2007; and finally, our over-aggressive attempt to offset the first two items by trying to triple the size of WA&D Services (causing numerous operational issues). In the second quarter of 2008, we do not believe that any of these previously experienced problems will cause year-to-year earnings shortfalls. Because of our new Chemtura Agreements, the costs of our fluids should begin to decline. Maritech’s current hedged prices are equal to or slightly better than those experienced in 2007. Finally, we believe that most, if not all, of our operational issues in WA&D Services have been eliminated. Couple this with continuing improvement in our Production Enhancement Division, and we should begin to show dramatic sequential earnings growth in the second quarter of 2008.

“Specifically, in Fluids, we anticipate that second quarter 2008 earnings should be the best that we will have reported since the second quarter of 2007 and could even surpass each quarter since 2006. Similarly, in WA&D Services, the second quarter should equal or surpass each quarter since the second quarter of 2007, and could surpass each quarter reported since 2006. In Maritech, it is anticipated that earnings will equal or surpass every quarter since the first quarter of 2007 and could even exceed the exceptional fourth quarter of 2006 (when large volumes of natural gas were hedged at $10.46/MCF). We expect second quarter earnings in Production Enhancement to continue to set sequential and all-time earnings records.

“The foregoing is not intended to describe a high-water earnings level for TETRA, where all factors align in a positive manner. To the contrary, we believe that third quarter 2008 earnings in all of our business segments should improve again over the current second quarter levels. What we do hope to show in the next two quarters is the beginning of a dramatic improvement in our bottom line earnings,” concluded Hertel.
