Advantage:   Bentonite has the characteristic of high mud yield, high gel strength and low shear. It can    improve the borehole stability especially in unconsolidated formation. The high performance    and low concentration of bentonite can reduce the dosage, cost and intensity of labor.   Application: Used for oil and gas well drilling and civil-engineering including drilling fluid system for  horizontal directional drilling, fluid solution for diaphragm walls and piles, lubrication fluids  for micro tunneling or pipe jacking, drilling fluids for water well, exploration and mining,  fluid solution for shield tunneling. relative knowledge for reference: Difference between Sodium Bentonite and Calcium Bentonite for drilling fluid application: Bentonite is often used as the material of drilling fluid. The mud yield of sodium bentonite  is higher and is commonly used in drilling industry. Calcium bentonite can't be used as  the material of drilling fluid before modification treatment.   Bentonite clay grade for water-base drilling fluid:   A) sodium bentonite API standard, commonly used in drilling industry   B) modified bentonite OCMA standard   C) drilling grade  (used in drilling fluid for plugging purpose)
