PAC™-L modified natural cellulosic polymer provides filtration control in mostwater-based drilling fluids without substantially increasing viscosity. PAC-Lpolymer, when added to a QUIK-GEL® or BORE-GEL® bentonite slurry, yields a fluid 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 and Functions

  • Filtration control in fresh or brackish water-based drilling fluids
  • Encapsulation of shale to prevent swelling and disintegration
  • Borehole stability in water sensitive formations
  • Minimized rod chatter, rotational torque and circulating pressure
  • Improved hole cleaning and core recovery


  • Effective in fresh water, salt water and brackish water-based drilling fluids
  • Effective in small quantities for filtration control
  • Does not significantly increase fluid viscosity
  • Non-fermenting
  • Resistant to harsh environments and contaminants
  • Free-flowing powder for easy addition
  • Compatible with other Baroid drilling fluid additives
