Bentonite Slurry Disposal: Transportation & Disposal Services
Small quantities of bentonite suspended in water form a viscous, shear thinning material often referred to as bentonite slurry. At high enough concentrations, bentonite suspensions begin to take on the characteristics of a gel. For these reasons, it is a common component of drilling mud used to curtail drilling fluid invasion by its propensity for aiding in the formation of mud cake.
