Drilling Grade
Bentonite having good thixotropic suspension properties and very low filtrate volume is selectively prepared as additive to the drilling fluid. It is widely used in petroleum drilling and drill for the pilling work eg. civil construction grade.
Petroleum industries through out the world follows the standards laid by American Petroleum Institute (API) and Oil Companies Materials Association (O.C.M.A.)
