POLYANIONIC CELLULOSE (PAC)
POLYANIONIC CELLULOSE (PAC)
CAS No.: 9004-32-4
Applications: Oil drilling
Embedded Files
Polyanionic Cellulose (PAC) is a high-performance water-soluble polymer derived from cellulose. It is widely used as a fluid loss control additive and viscosity modifier in various water-based systems. Thanks to its excellent salt resistance, thermal stability, and environmental compatibility, PAC plays a crucial role in oil drilling fluids.
Advantages of PAC:
Excellent salt and calcium resistance
Effective in both freshwater and seawater mud systems
High thermal stability and biodegradability
Compatible with other drilling fluid additives
Improves the overall performance and cost-efficiency of drilling operations
1. PAC R (Regular Viscosity Grade)
1. PAC R (Regular Viscosity Grade)
PAC R is a high-viscosity grade designed primarily for drilling fluids used in oil and gas exploration. It provides excellent fluid loss control, enhances rheological properties, and improves borehole stability in both fresh water and salt water systems.
Applications: Oil and gas drilling fluids, completion fluids
Functions: Reduces fluid loss, increases viscosity, stabilizes shale, and improves carrying capacity of drill cuttings

2. PAC LV (Low Viscosity Grade)
2. PAC LV (Low Viscosity Grade)
PAC LV is a low-viscosity grade mainly used where fluid loss control is required but minimal impact on viscosity is desired. It performs effectively in high-salinity and high-temperature conditions, maintaining stable performance across a wide pH range.
Applications: Saltwater drilling fluids, cement slurries, and workover fluids
Functions: Reduces filtration rate, minimizes solids invasion, and improves mud stability without thickening the system
