Polyanionic Cellulose (PAC) is a high-performance, water-soluble polymer derived from cellulose, specifically engineered for use in water-based drilling fluids. PAC is widely recognized for its exceptional fluid loss control and viscosity building properties, making it an essential additive for maintaining wellbore stability, optimizing hole cleaning, and enhancing overall drilling efficiency. It is particularly effective in fresh water, sea water, and saturated salt water mud systems, providing consistent performance across diverse drilling environments.

How PAC Works: Polyanionic Cellulose functions by adsorbing onto clay particles and drill solids, forming a protective colloidal barrier that reduces permeability and minimizes filtrate invasion into permeable formations. The polyanionic nature of the polymer provides enhanced stability in the presence of electrolytes, allowing it to maintain its fluid loss control and viscosifying properties even in high-salt environments where conventional polymers may fail. This makes PAC particularly valuable for offshore drilling and operations using saltwater-based muds.

Key Benefits of PAC:
• Superior Fluid Loss Control – Effectively reduces filtrate invasion, maintaining wellbore stability and formation protection.
• Excellent Viscosifying Properties – Enhances mud viscosity for improved cuttings suspension and hole cleaning.
• Salt Water Compatibility – Performs exceptionally well in fresh water, sea water, and saturated salt water systems.
• Temperature Stability – Maintains properties under elevated downhole temperatures.
• Shale Inhibition – Helps stabilize reactive shales and prevent hydration-related issues.
• Non-Fermenting – Resistant to bacterial degradation, ensuring long-term stability.
• Compatible with Other Additives – Works synergistically with other drilling fluid chemicals.

PAC Grades & Their Applications:
• PAC HV (High Viscosity) – Provides maximum viscosity building for enhanced cuttings suspension in large-diameter holes.
• PAC R (Regular Viscosity) – Balanced performance for general-purpose fluid loss control and viscosity.
• PAC LV (Low Viscosity) – Designed for filtration control with minimal impact on rheology.
• PAC ULV (Ultra Low Viscosity) – Maximum filtration control with negligible viscosity increase.
