Business/Energy Editors

THE WOODLANDS, Texas--(BUSINESS WIRE)--March 20, 2000

TETRA Technologies, Inc. ("TETRA" or the "Company") (NYSE:TTI) today announced that its wholly owned affiliate, TETRA Technologies Norge ("TTN"), a Norwegian company, has entered into a Residuals Processing Agreement with Renovasjon Nord A/S ("RN"). RN has existing contracts with a number of oil and gas exploration companies to take and process volumes of liquid and solid residuals.

TTN combines the residuals processing expertise of TETRA Process Services with the infrastructure and exploration/production energy relationships of TETRA International. TTN has begun construction of a processing facility in Kristiansund, Norway. RN currently has contracts to process residuals with four major exploration/production operators working offshore. Most contracts are multi-year.

TETRA's Chief Operating Officer Geoffrey M. Hertel stated, "In 1999, we reviewed the existing U.S. market for our TETRA Process Services subsidiary. This market is involved in processing oily residuals from refineries. We found it to be a $60 million annual market. While analyzing our options, we determined that a $200 million annual market existed for similar services to exploration and production companies. Much of this market involves offshore operations in foreign areas. This contract in Norway is our first significant success penetrating this market."

Hertel continued, "Our longstanding relationship with energy companies in the North Sea and our existing operating entity in Norway laid the groundwork for this contract. Couple this with the technology and knowledge of residuals processing brought by TETRA Process Services and you can see why we were able to obtain this new business."

"This onshore facility will not only process materials from offshore platforms, but will service other local customers of RN. We hope that this type of contract becomes prototypical of contracts that we are exploring in other foreign areas. In relationship to TETRA Process Services' current size, this contract would be deemed material," Hertel concluded.

TETRA is primarily an energy services company, including an integrated chemicals operation that supplies feedstocks to energy markets, as well as other markets.
