Bentonite Extender

AM2F Energy Bentonite Extender is used with water-based drilling fluids. It has a shear-thinning property that exhibits high lift capacity and low shear rate, maximixing the drill rate.


AM2F Bentonite Extender is used in in freshwater, seawater, high brine water and solids free brine systems. It acts as a viscosity agent, fluid loss controller, bentonite extender, encapsulator, bore-hole stabilizer and flocculation agent.
