This contract is for completion fluids and associated services on Petrobras’s deepwater high temperature-high pressure wells offshore Brazil.

The contract term is for four years, with an option for an additional four years. Work is expected to begin by the 2008 year-end. The contract comes at a time Tetra is planning to expand its fluids manufacturing operations in Arkansas, US.

Geoffrey Hertel, president and CEO of Tetra Technologies, said: Tetra is very pleased to be offering our products and services to Petrobras, under this contract. The area covered and types of wells reflected in this contract have been highlighted by Petrobras, with a number of significant discoveries. While Tetra has previously supplied Petrobras and ex-national oil companies with completions products and services in Brazil, this is by far our largest fluids contract in this country.
