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.
