Api Drilling Bentonite

API Drilling Bentonite is most commonly known for its use as a major component of drilling mud, particularly for oil wells, but is also widely used as an additive for viscosity and filtration control. When exposed to water, Bentonite, characteristic of all clays, swells considerably, making it ideal for protecting subterranean formations from invasion by the other drilling fluids making up the mud by providing a thixotrophic effect.
