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 (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.
