March 19, 2009 (The Woodlands, Texas), TETRA Technologies, Inc. (TETRA or the Company) (NYSE:TTI) updated the progress of its new fluids facility in El Dorado, Arkansas and also commented on the status of its contractual relationship with Chemtura Corporation and its affiliates (Chemtura).

Geoffrey M. Hertel, President and Chief Executive Officer of TETRA, stated, “The start-up of our new facility in El Dorado, Arkansas is currently slightly ahead of schedule, with initial operations expected to commence in the third quarter of 2009, followed by commercial operations in the fourth quarter of 2009. As had previously been announced, in 2006 we entered into a number of agreements with Chemtura relating to our Arkansas operations. On March 18, Chemtura announced that it and twenty-six of its affiliates had filed voluntary petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Although it is impossible to predict the outcome of contractual arrangements as a result of the bankruptcy filings, we do not believe that Chemtura’s filing will have a material impact on our operations. However, TETRA has contingency plans for the procurement of alternative feedstock supplies.

“We believe that the agreements with Chemtura are symbiotic, in that they benefit both parties. We further believe that Chemtura has an incentive to continue our existing agreements and we are optimistic that the bankruptcy filing will not affect our existing arrangements; however, no assurances can be given that the agreements will survive the bankruptcy proceeding. TETRA did not base its Arkansas investment solely on the operations of one third-party plant. If necessary, TETRA potentially can turn to another bromine producer that has a plant in close proximity to our El Dorado facility, as a way to mitigate the impact of any adverse action by Chemtura. Furthermore, starting in the 1990s, TETRA acquired approximately 33,000 gross acres of brine leases in the area. With additional capital expenditures, these leases could allow us to supply our own brine to the facility, if necessary. In summary, while we believe that our agreements with Chemtura are mutually beneficial to the parties and that Chemtura has an incentive to continue our agreements, TETRA does have other options regarding feedstock to our El Dorado fluids plant, should issues arise regarding Chemtura’s ability to supply those feedstocks,” concluded Hertel.
    
TETRA is an oil and gas services company, including an integrated calcium chloride and brominated products manufacturing operation that supplies feedstocks to energy markets, as well as other markets.
