Product overview

Polyanionic Cellulose is a high-substitution anionic cellulose derivative used for filtration control and rheology in water-based drilling, drill-in and completion fluids. PAC-LV is selected where low viscosity contribution is preferred, while PAC-HV can add both fluid-loss control and viscosity.

Function & Usage

  • Build Drilling-Fluid Rheology

    Supports viscosity, suspension or carrying performance in compatible drilling-fluid and oilfield systems. Typical uses: Fluid-loss control in freshwater, seawater and saltwater drilling fluids, Viscosity and suspension support with PAC-HV, Low-solids and reservoir drill-in fluid systems.

  • Build Drilling & Completion Fluids

    Supports filtration control, rheology, density, shale inhibition or reservoir-compatible brine design in suitable drilling, drill-in, completion and workover fluids. Typical uses: Fluid-loss control in freshwater, seawater and saltwater drilling fluids, Viscosity and suspension support with PAC-HV, Low-solids and reservoir drill-in fluid systems.
