Performance biocides for oil & gas fields, water treatment operations
With experience gained over the last 25 years, Rhodia has secured a growing reputation as an innovative partner for service companies supporting the oil & gas field and water treatment industries.
Rhodia’s biocide TOLCIDE® PS is targeted at a wide range of applications in oil & gas field and water treatment markets. TOLCIDE ® PS is a successful, fast-acting and powerful microbiocide, 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.
Innovative TOLCIDE® PS A-series to combine performance and respect of the environment
Rhodia’s has designed a new TOLCIDE® PS A-SERIES range combining 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,effective over a wide pH range, and easily analysed in the field, is approved for use in many environmentally sensitive areas of the world including the North Sea.
This new biocide products help develop cost-effective and environmentally friendly solutions to maximize production from oil and gas reservoirs while reducing the overall consumption of chemicals by 20% (in Laboratory tests).
Reducing the overall consumption of biocides with eco-friendly solutions is a major challenge in the oilfield market.
Rhodia has design TOLCIDE® PS A-SERIES biocide technology to solve problems of water clarity, scale formation, corrosion and microbiological fouling in the potable, industrial and waste water markets. Our customers enjoy the benefits of improved process efficiency and have the solutions to comply with the ever increasing legislative demands for environmental protection, conservation and improved human health in the use of water.
Feature and benefits of the new biocide TOLCIDE® PS A-SERIES in Oilfield
Control reservoir souring
TOLCIDE®PS A-SERIES is the product of choice for use in water injection or (Produced Water Re-Injection) PWRI systems to help control reservoir souring and “sweeten” sour reservoirs.
Control Microbial induced Corrosion (MIC)
TOLCIDE®PS A SERIES is the product of choice for controlling MIC throughout oilfield water systems due to its ability to penetrate bio-films and control sessile bacteria and its ability to remove porous FeS deposits which accelerate pitting corrosion.
Flow lines (in conjunction with mechanical cleaners)
Facilitate demulsification in sour systems
TOLCIDE®PS A-SERIES can supplement conventional demulsification processes by controlling particulate FeS build-up (both by controlling SRB & dissolving existing FeS particles).
Improving separated water quality
Reducing overboard sheen
Removal of “FeS” based deposits… including “Schmoo”
Outperformance of standard THPS formulations
TOLCIDE®PS A SERIES has supplementary dispersion and scale control properties.
TOLCIDE®PS A SERIES has an outstanding rating as it is biodegradable and non-bioaccumulative, and on discharge rapidly breaks down to environmentally benign products. The biocide formulation is halogen free.
