Feature of our product: -good adhesion -good suspension -good lubricity -good thixotropy -good plasticity -good catalytic -good exchangeability -good adsorbability 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.   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.
