Product name: Poly anionic cellulose
Appearance: Free flowing off-white powder
Application:
PAC-HV is 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.
PAC-LV is for use in solids-laden,water-based drilling fluids,which can effectively reduces the filtration rate of many water-based drilling fluids,without causing significant increases in viscosity or gel strengths.
