Drilling Polymer is a readily dispersible polymer additive designed to provide shale stabilization in freshwater to saltwater drilling fluids ranging from low solids muds. It acts as a viscosifier, and friction reducer, while also providing some fluid-loss control. Drilling Polymer forms a protective polymer film on the drill pipe and bit as well as on the walls of the borehole which helps to provide lubrication when drilling in troublesome formations. It is ideally suited for use in horizontal directional drilling, water well, mining, and tunneling applications.
