Polyanionic cellulose (PAC) is a kind of nonionic cellulose ether. The PAC polymer featured the properties of high purity, high DS, particularly high viscosity (PAC-HV), or low viscosity (PAC-LV). These products are demi-natural polymer additive, thickening agent, filtrate reducer.
Polyanionic cellulose is an indispensable product for drilling mud making. It is a high purity product. The water solution of this PAC polymer powder is transparent and viscid. As a water-soluble polymer, polyanionic cellulose dissolves immediately in cold/hot water. And it can be used as a thickening agent, rheology controller, bond, stabilizer, colloid protector, suspending agent, and filtrate reducer.
Polyanionic cellulose is a good drilling mud additive. It is also an important material for confecting well liquid, a high mud volume product that featured high acid-resistance and salt-resistance ability. PAC is a good filtrate reducer with the capacity of increasing viscosity and anti-high temperature (150°C) in the freshwater, seawater, or even saturated brine well-completion liquid. This polymer is suitable for confecting the completion fluid with these 3 kinds of water above.

PAC-HV is for water-based drilling fluids. It can effectively reduce the filtration rate of many water-based oil and gas drilling fluids. And the high viscosity PAC polymer may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environments.
PAC-LV is for use in solids-laden, water-based drilling fluids, which can effectively reduce the filtration rate of many water-based drilling fluids. The low viscosity PAC polymer can not cause significant increases in viscosity or gel strength.
PAC R is a cost-effective additive to reduce the API filtration rate of many water-based drilling fluids. Such as freshwater, seawater, saturated saltwater, and solids-free brines, native mud, flocculated mud, inhibited mud, and contaminated systems. PAC R increases and stabilizes viscosity to improve rheology, wellhole cleaning, and suspension property by coating and encapsulating cuttings and solids of drilling fluids. PAC R is effective over a wide range of pH environments. It lubricates solids in the system, improves wall cake characteristics, and reduces the potential for the stuck pipe.
