PAC HV is a high-quality grade of poly-anionic cellulose polymer which is widely use to minimize filtration and increase rheological properties in water-based drilling fluid. It is stable up to 300°F and is applicable in different types of water such as fresh to high-saline ones. PAC HV is optimized for drilling fluids needing low filtration properties as well as high rheological characteristics.
