PAC-R, a high molecular weight polyanionic cellulose, provides filtration control and supplementary viscosity in most water-based drilling fluids.
*Applications/Functions: Control filtration rates, Retard shale swelling and disintegration, Provide supplementary viscosity in fresh water, sea water, and brine-based fluids
*Advantages: Effective in small concentrations for viscosity and filtration control, Stable at temperatures up to 300'F(149'C), Effective in moderate to high pH systems, Nontoxic, Does not require a bactericide |
