Rhodia extends its biocide Tolcide® product range

News release

Paris (France) — Cranbury – NJ (USA) December 11, 2008 — Rhodia announces the launch of new biocide products that help develop cost-effective and environmentally friendly solutions to maximize production from oil and gas reservoirs.

Rhodia’s innovative new TOLCIDE® PS A-series range combines a biocide with a proprietary polymer that is both biodegradable and non-bioaccumulative. This non-foaming formulation, fully miscible with water and insoluble in oils, is approved for use in many environmentally sensitive areas of the world including the North Sea. This new range is based on the successful fast- acting, powerful microbiocide, TOLCIDE ®, designed to eliminate bacteria from oilfield waterflood operations or fracturing fluids in oil and gas reservoirs. It is also used in industrial water-treatment installations.

"Reducing the overall consumption of biocides with eco-friendly solutions is a major challenge in the oilfield market. This innovative formulation combines a well-known powerful biocide and an original polymer-based system to achieve excellent control over bacteria and biofilm combined . Thanks to this new biocide, we have seen reduction of more than 20 percent of chemicals in laboratory testing. These results have been confirmed by initial feedback from our customers," said Bruno Langlois, Business Development Director of Rhodia Novecare’s Oil Field Market.

“As the global leader in this biocide market, Tolcide ® technology demonstrates our ability to increase product performance while developing environmental benefits” added Brian Downward , Business Director of Rhodia Novecare’s Oil Field Market. ”With more than 25 years experience in oil field and taking advantage of our technological and industrial expertise in sustainable development chemistry, we are committed to helping our customers in this approach.”

Rhodia supplies a wide range of performance chemicals for oil drilling, stimulations, cementing and production fluids, drawing on a variety of technologies that includes guar biopolymers (Jaguar®), synthetic polymers, surfactants, phosphorus derivatives (Aquarite®) and biocides (Tolcide®).
