Polyanionic cellulose regular (PAC-R) is used as a viscosity builder and water loss reducer in all water-based drilling fluids, as well as in salty drilling fluids. PAC-R provides stability of the well by preventing hydration and dispersion of the shale. It is not affected by bacterial degradation and is used in a wide pH range.
It is unaffected and used in a wide pH range.
