PAC-LV (Low Viscous Polyanionic Cellulose)
Introduction
PAC-LV is high-quality Polyanionic Cellulose Polymers. It is used in most water-based drilling fluids including fresh water, seawater and brine up to 300°F. PAC-L has a minimal increase in rheology, is non-toxic and does not require a biocide. PAC-L is can also encapsulate solids to control dispersion of active shale.
Applications/Functions
Control filtration rates with minimal increase in rheology
Aids in the formation of a tough, thin filter cake to minimize the potential for differential sticking
Advantages
Temperatures stable up to 300°F
No fermenting, no biocide needed
Effective in fresh water, seawater and brine fluids
Functions in all pH range
Produces thin, slick, tough filter cake
Inhibit hydratable, swelling shales
Environmentally compatible
