    PAC-R

    Description

    PAC-R modified natural cellulosic polymer provides filtration control in most water-based drilling fluids. PAC-R additive, when added to a 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.

    Applications/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

     

    Advantage 

    Effective in fresh water, salt water and brackish water-based drilling fluids
    Effective in small quantities for filtration control
    Non-fermenting
    Compatible with other Baroid drilling fluid additives
    Resistant to harsh environments and contaminants

     

    Typical Properties

    Appearance                              White, free-flowing powder
    pH (1% aqueous solution)        8.0

     

    Recommended Treatment

    Using a Venturi mixer, or into vortex of a high-speed stirrer, add slowly and uniformly to the entire circulating system.

    Note: Very salty waters may require twice as much PAC-R additive as fresh water. Preferably,

    PAC-R additive should be mixed in fresh water before it is added to very salty water.

     

    Packaging
    PAC-R filtration control additive is packaged in 50-lb (22.7 kg) or 25KG bags.

     

    PAC-L

    Description

    PAC-L modified natural cellulosic polymer provides filtration control in most water-based drilling fluids without substantially increasing viscosity. PAC-L polymer when added to a QUIK-GELor BORE-GEL slurry, yields a drilling mud system suitable for drilling in sandy formation. PAC-L polymer can be added to vegetable or mineral oil to provide an oil-based fluid suspension, which can be poured into drill string directly.

     

    Applications/Functions

    Can provide filtration control in fresh or brackish water-based drilling fluids
    Can reduce fluid loss without significantly increasing fluid viscosity
    Can encapsulate shale to prevent swelling and disintegration
    Can promote borehole stability in water sensitive formations
    Can minimize rod chatter, rotational torque and circulating pressure
    Can improve hole cleaning and core recovery

     

    Advantages

    Effective in fresh water, salt water and brackish water-based drilling fluids
    Effective in small quantities for filtration control
    Non-fermenting
    Compatible with other Baroid drilling fluid additives
    Resistant to harsh environments and contaminants

     

    Typical Properties

     

    Appearance                              White, free-flowing powder
    pH (1% aqueous solution)        6.5–8.5

     

    Recommended Treatment

    Using a Venturi mixer, or into vortex of a high-speed stirrer, add slowly and uniformly to the entire circulating system.
