Our PAC-HV is used as drilling fluid additives.
PAC-HV is short for polyanionic cellulose of high viscosity. It is high molecular weight, high viscosity polymer for water-based drilling fluids, which can effectively reduces the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environments.
