Drill Rig Parts - Drispac Polymers PAC-R for Drilling Fluid HV-CMC

Drispac® Polymers are high-quality polyanionic cellulose polymers.

PAC™-R modified natural cellulosic polymer provides filtration control in most water-based drilling

fluids.PAC-R additive, when added to a QUIK-GEL® slurry, yields a drilling mud system suitable for drilling

in sandy formation. PAC-R additive can be added to vegetable or mineral oil to provide an oil-based fluid

suspension, which can be poured into drill string directly. PAC-R additive is also used in air/gel-foam

drilling.

Advantages

Controls fluid loss

Promotes fragile gels

Inhibits hydratable, swelling shales

Increases resistance of clay mud to contamination

Non-fermenting, no preservative needed

Good thermal stability

Produces thin, slick, tough filter cake

Environmentally compatible

Retards drilled solids build-up

Eliminates fisheyes in mud

Reduces friction and can reduce ECD

Works well on rigs with poor mixing facilities

Works well at any salinity

Functions

Can provide filtration control in fresh or brackish water-based drilling fluids

Can promote borehole stability in water sensitive formations

Can minimize rotational torque and circulating pressure

Can improve hole cleaning and core recovery

Can stiffen foam to improve cuttings transport in air/foam drilling

Can reduce air requirements, uphole velocity and borehole annulus pressure in air/foam drilling

Appearance ----- White, free-flowing powder

PH (1% aqueous solution) ----- 6.0-8.5

Packaging PAC-R filtration control additive is packaged in (25 kg) bags.
