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
