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 (PAC R) can meet requirement of M-I SWACO, HALLIBURTON, BAKER HUGHES, Chevron and meet the API 13A Section 18 Specification.

Advantages

• Effective in fresh water, salt water, and brine-based fluids
• Controls fluid loss
• Inhibits hydratable, swelling shale
• Environmentally compatible
• Does not require a bactericide
• Is stable at temperatures up to 300°F /149°C

Applications

• Controls filtration rates
• Retards shale swelling and disintegration
• Provide supplementary viscosity in fresh water, sea water, and brine-based fluids

Recommended Treatment

AddPAC-HV (PAC R) in concentration of 5-2.0 lb/bbl (1.43-5.71 kg/m³) to any active system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
