VIS is a premium grade purified high viscosity, high molecular weight polymer, used as an effective viscosifier and reduce fluid loss to water-based drilling fluids.
Drilling mud additives VIS is a premium grade purified high viscosity, high molecular weight polymer, used as an effective viscosifier and reduce fluid loss to water-based drilling fluids.
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
Extends life of foam or stiff foam in air drilling
Recommended Treatment:
Add drilling polymer VIS 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.
Applications
Controls filtration rates
Retards shale swelling and disintegration
Rapid increase in viscosity
Application Industry:
PANDA Drilling Polymers VIS is used for Civil Construction, Geotechnical, HDD, Mining drilling, and Waterwell drilling.
