Highly purified Polyanionic Cellulose (PAC) is the primary fluid-loss reducer in water-based drilling fluids. Drilling fluids often contain Polyanionic Cellulose (PAC). It shares structural similarities with carboxymethyl cellulose (CMC) at the molecular level. In contrast to CMC, it has superior filtration-reducing, anti-salt, anti-collapse, and high-temperature resistance properties. Temperatures of up to 150 degrees Celsius are safe for use. An increased degree of Carboxymethyl substitution and potentially lower levels of residual Sodium Chloride make PAC a premium product. Polyanionic cellulose (PAC) comes in two main varieties: PAC HV (High Viscosity) and PAC LV (Low Viscosity) (Polyanionic cellulose Low Viscosity). With the mixture of other chemicals, PAC is added to drilling fluids to make mud bit cool and lubricate, and suspension formation of cuttings, work efficiently in transportation of drilled material to the surface, and balancing the formation pressure across oil well
PAC can help avoid potentially disastrous outcomes like well blockages and bore collapses during the production process. Because of its low water loss qualities. It uses to adjust the viscosity level and local conditions.
