For the purification process, Bentonite was first sieved to get only particles with size less than 2 μ m; afterwards, it was homoionized with a solution of 1 N NaCl and then filtered. In order to obtain the acid-activated clay, the parent Bentonite was dispersed in a solution of HCl (1.0 M) and vigorously stirred at 80 °C for 4 h.

Bentonite is used in drilling mud to lubricate and cool the cutting tools ( drill bit ), to remove cuttings, to stabilize the borehole walls, and to help prevent blowouts (by maintaining a sufficient hydraulic pressure in the well). Bentonite also curtails drilling fluid invasion by its propensity for aiding in the formation of mud cake. [11]
