Polyanionic Cellulose (PAC)




Polyanionic Cellulose (PAC) (Polyanionic Cellulose) is a kind of nonionic cellulose ether

featured the properties of high purity, high DS, particularly high viscosity or low viscosity.

These products are demi-natural polymer additive, thickening agent, filtrate reducer.

Polyanionic Cellulose (PAC) is an indispensable product for drilling mud making.

Polyanionic Cellulose (PAC) is high purity product; the water solution of this white powder is

transparent and viscid. As water-soluble polymer, it dissolves immediately in cold/hot water and

can be used as a thickening agent, rheology controller, bond, stabilizer, colloid protector, suspending agent, and filtrate reducer.

Polyanionic Cellulose (PAC) is a good drilling mud additive and also an important material

for confecting well liquid, a high mud volume product that featured high acid-resistance and

salt-resistance ability. Polyanionic Cellulose (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. Polyanionic Cellulose (PAC) is suitable for confecting the

completion fluid with these 3 kinds of water above

Polyanionic Cellulose (PAC) -HV is for water-based drilling fluids, which can effectively reduces

the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase

and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environment.

Polyanionic Cellulose (PAC) -LV is for use in solids-laden, water-based drilling fluids,

which can effectively reduces the filtration rate of many water-based drilling fluids,

without causing significant increases in viscosity or gel strength.

Polyanionic Cellulose (PAC) R is a cost-effective additive to reduce API filtration rate of

many water based drilling fluids including freshwater, seawater, saturated saltwater and

solids-free brines, native mud, flocculated mud, inhibited mud and contaminated systems.

Polyanionic Cellulose (PAC) R increases and stabilizes viscosity to improve rheology,

wellhole cleaning and suspension property by coating and encapsulating cuttings and

solids of drilling fluids. Polyanionic Cellulose (PAC) R is effective over a wide range of

pH environments. It lubricates solids in the system, improve wallcake characteristics and reduces the potential for stuck pipe.

Package and Storage:

Packed in multiply paper bags or fiber drums (25KG), or as per customer requirement; keep dry.
