Property:
PAC is a kind of anionic cellulose with featured the properties of high purity, high DS. It is demi-natural polymer additive, thickening agent, filtrate reducer.
PAC is an indispensable product for drilling mud making. It is high purity product. The water solution is transparent and viscid. As one kind of water-soluble polymer, PAC 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 is 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. PAC is suitable for confecting the completion fluid with these 3 kinds of water above.
Usage:
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.
Package:
25kgs bags with pallets.
