PacRite-R: is a 92% polyanionic cellulose water-soluble polymer designed to control fluid loss and increases viscosity in water-based drilling fluids. This in short, seals the tiny holes and cracks in the surface of the bore wall. It creates a wall cake that aids in reducing the amount of fluid absorbed by the formation that could cause sloughing and pack off down hole.
