BENTONITE GRADE DETAILS

Drilling Grade Bentonite Producers Manufacturer

and Supplier:

Bentonite is as a mud constituent for oil- and water- well drilling. Its role is mainly to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head. The special higher mud yield results in using less quantity of Bentonite for the same standard mud. This results in lesser requirement of Bentonite.

Retains thixotopic properties when met with brine and high temperature in deep drilling Gives high barrel yield Withstands formation pressure

Construction Grade Bentonite Producers

Manufacturer and Supplier:

Bentonite in civil engineering applications is traditionally used as a thixotropic, support and lubricant agent in

diaphragm walls and foundations, in tunnelling, in horizontal directional drilling (HDD) and pipe jacking.

Bentonite, due to its viscosity and plasticity, is also used in Portland cement and mortars.
