Ferrochrome lignosulfonate is a fluid loss control agent used in drilling fluids to resist high temperatures and salty solutions. It reduces the apparent viscosity of fresh water drilling muds by at least 85% and salt water muds by at least 70% under normal temperatures, and reduces the viscosity of fresh water muds by at least 65% and salt water muds by at least 55% under high temperatures. Ferrochrome lignosulfonate is a yellow brown powder packaged in 25kg woven bags.
