Tolcide® PS50A is a rapid acting, powerful microbiocide which has been designed to control bacteria in oilfield water-flood operations and production systems. It can be used to control reservoir souring in oilfields contaminated with sulphate reducing bacteria and alleviate production problems associated with iron sulphide deposition.
With a relatively low order of aquatic toxicity and being both biodegradable and non-bioaccumulative, Tolcide® PS50A is approved for use in many environmentally sensitive areas of the world, including the North Sea.
Tolcide PS50A is supplied as a liquid formulation which is non-foaming, fully miscible with water and insoluble in oils.
