Product Description

API Drilling Starch is an effective and economical fluid loss agent in water based drilling fluids, which is a starch derivative. It is not bacterial degradation when at **0℃, environmentally acceptable and non-toxic. Modified Starch can produce a thin, slick, tough filter cake and promotes faster penetration rates with reducer friction. It can be used in all kinds of drilling fluid systems.
