Detailed Description
Product Description PAC HV (PAC R) is a premium grade purified high viscosity, high molecular weight, polyanionic cellulose, designed to provide viscosity and reduce API filtration rate to water-based drilling fluids. PAC HV can meet requirement of M-I SWACO, HALLIBURTON, BAKER HUGHES. Advantages Reduces the filtration rate of the fluid Increases and improves the fluid rheology (including suspension and hole cleaning) Stabilizes fluid rheology in the presence of contaminants Coat and encapsulate cuttings and solids in the drilling fluid, thereby inhibiting the swelling and disintegration of water sensitive solids Improves the character and consistency of wall cake, thereby reducing the potential for stuck pipe Application Range and Method When use, directly mixed into drilling fluid. Recommend dosage: Add 0.5-2.0 lb/bbl (1.43-5.71 kg/m³) of PAC-HV filtration control agent slowly through the mud hopper.
