Polyanionic Cellulose Regular (PAC-R) is used as a viscosity builder and fluid loss reducer in all water-based drilling fluids, and it is also suitable for use in saltwater drilling fluids. PAC-R prevents shale hydration and dispersion, thereby ensuring wellbore stability. It is resistant to bacterial degradation and can be used over a wide pH range.
