Poly Anionic Cellulose (PAC-RG)
PAC-RG is a water-soluble, cellulose-based anionic polymer used widely in Water-Based Drilling Fluids (WBM).It is primarily designed for fluid loss control but also provides moderate viscosity and stabilization to the mud system. PAC-R is a standard material used across oil & gas, mineral exploration drilling, and workover fluids.
