Drilling Fluid Additives Technical high viscosity carboxymethyl cellulose
PAC HV is high viscosity polyanionic cellulose and low molecular weight, low viscosity type polymer designed specifically for use in solids-laden, water-based drilling fluids, which can effectively reduces the filtration rate of many water-based drilling fluids, especially solids-laden fluids, without causing significant increases in viscosity or gel strengths.
