Product performance and characteristics:
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. PAC is an indispensable product for drilling mud making. 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. 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. It 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. It is suitable for confecting the completion fluid with these 3 kinds of water above.
Applications:
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.
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.
Packing:
Packed in 25kg kraft paper bags with PE liner inside
