PAC-HV 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-R can provide secondary viscosity and effective at low concentrations. It is non-toxic and does not require a biocide. PAC-R will create an envelope around exposed shales and cuttings to encapsulate them, reducing dispersion and permitting improvement of wellbore integrity. The encapsulation protects the shale from exposure to water.
Control filtration rates and provide supplementary viscosity
Aids in the formation of a thin, resilient, low-permeability filter cake to minimize the potential for differential sticking and the invasion of filtrate and mud solids into permeable formations.
Temperatures stable up to 300°F
No fermenting, no biocide needed
Effective in fresh water, seawater and brine fluids
Functions in moderate to high pH range
Encapsulates shale particles to inhibit swelling and dispersion
White to yellow powder
pH (1% aqueous solution)
A typical treatment range is 0.5-2 ppb
