CELPOL® Polyanionic Cellulose
CELPOL® products are low- to high-viscous polyanionic celluloses developed for use in drilling fluids, fracturing, workover and completion fluids. They provide excellent fluid loss control and, depending on grade, will provide supplemental increase of apparent viscosity and yield point to assist in solids transfer from the bit region to the surface. Additionally, these grades contribute to shale inhibition by providing a protective layer over active clay surfaces. CELPOL® polymers have excellent thermal stability and can be used in a variety of fluid types, from freshwater to sea water and saturated, salt water mud systems.
