Our bentonite is a non-treated (or natural) sodium bentonite which meets the requirements of API specification 13A/ISO 13500 section 11 (OCMA grade). It used for its unique rheological properties: at relatively low concentrations, bentonite suspensions develop a yield stress and show strong shear thinning behavior.
Applications for Bentonite
As bentonite provides viscosity and gelling characteristic to water-based drilling fluids, so bentonite is used as a viscosifier to suspend weighting agent and cuttings.
Bentonite clay is also used as a filtrate reducers to decrease fluid loss from a wellbore fluid, forming a thin tough filter cake.
In oilwell cementing, bentonite is used as an extender to increase the viscosity of oilwell cement slurries prior to down-well injection.
