    Bentonite in Drilling Mud Advanced Science News

    Apr 24, 2015· The most common use of bentonite is in drilling fluids. The bentonite in the flush fluid lubricates and cools the cutting tools while protecting against corrosion. As the drilling fluid generates hydrostatic pressure in the borehole, it hinders fluid and gas penetration. The drilling liquid conveys the drill cuttings to the surface.

    Feb 01, 2015· The hydraulic conductivity of the bentonite cake prepared from B3 had the highest overall k, but was the least affected when exposed to acidic solutions. An increase in k of ∼10× was observed in B3 at 0.5 M which could be attributed to the chemical composition of exchangeable cations (Mg 2+ ) relative to GCL1 and GCL2 which contained sodium bentonite.
