Polyanionic cellulose (PAC HV&LV) is an effective additive for reducing the A.P.I. filtration rate of many water based drilling fluids. PAC HV&LV may also be used to increase viscosity and improve wellhole cleaning in a wide variety of fluid environments. PAC HV&LV provides a cost effective means of improving water based drilling fluid performance.

Applicable Fluid Types:

PAC-HV&LV is applicable in the following general types of fluid systems.

• Freshwater Muds
• Seawater Muds
• Saltwater Muds (up to and including saturation)
• KCL Muds
• Solids Free Brine (NACL and KCL)
• Native Muds

PAC-HV&LV may be used efficiently in the indicated types of fluid to:

• Reduce the filtration rate of the fluid
• Increase and improve the fluid rheology (including suspension and hole cleaning)
• Stabilize fluid rheology in the presence of contaminants
• Coat and encapsulate cutting and solids in the drilling fluid, thereby inhibiting the swelling and disintegration of water sensitive solids.
• Improve the character and consistency of wallcake, thereby reducing the potential for stuck pipe.

Packaging:

Packaged in 25 kg multiwall paper sacks.
