CSOILFIELD offers alternative special solutions to stimulate well and maximize the production. S-APHBREAK is a delayed acid generator used for the slow release of acid to act as a filter cake breaker, oxidizer and gel breaker. When spotted down-hole, it reacts with water, generates acid and subsequently dissolves the calcium carbonate and polysaccharide. The cost-effective system allows time to enable running work-over and completion operations, increasing hydrocarbon production rates. Advantages include low cost, ease of mixing and pumping, and excellent filter cake removal with minimal formation damage.
