PRODUCT DESCRIPTION
PAC HV1 is a premium grade purified high viscosity, high molecular weight, polyanionic cellulose, and meet the API 13A Section 18 Specification.
APPLICATION
(1) PAC HV1 is designed to provide viscosity and reduce API filtration rate to water based drilling fluids. PAC HV1 can meet requirement of M-I SWACO, HALLIBURTON, BAKER HUGHES, Chevron a
(2) Controls filtration rates
(3) Retards shale swelling and disintegration
(4) Provides supplementary viscosity in fresh water, sea water and brine-based fluids
(5) Be used in mining drilling engineering
ADVANTAGES
(1) Effective in fresh water, salt water, and brine-based fluids
(2) Controls fluid loss
(3) Inhibits hydratable, swelling shale
(4) Environmentally compatible
(5) Does not require a bactericide
(6) Stable at temperatures up to 300°F /149°C
USAGE
Add PAC-HV1 in concentration of 1.4 to 5.7 kg/m³ (0.5 to 2.0 lb/bbl) to any active system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
STORAGE
(1) Avoid high-intensity extreme pressure and prolonged exposure to strong sunlight.
(2) Keep bag closed.
(3) Keep away from heat, sparks and flames.
