Polyanionic Cellulose

Descripción del producto

Property:

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 
(**0°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.
 

Usage:
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.
PAC-RV 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. 
PAC-RV increases and stabilizes viscosity to improve rheology, wellhole cleaning and
suspension property by coating and encapsulating cuttings and solids of drilling fluids. 
PAC-RV is effective over a wide range of pH environments. It lubricates solids in the system,
improve wall cake characteristics and reduces the potential for stuck pipe.

Package and Storage:
