Polyanionic Cellulose

Brief Introduction:

filtration control and viscosity control

PAC-L, medium molecular weight polyanionic cellulose, provides filtration control and light viscosity in most water-based drilling fluids.

 

Control filtration rates

Retard shale swelling and disintegration

Provide supplementary viscosity in freshwater, seawater, and brine-based fluids

Add 0.5-2.0 lb/bbl (1.43-5.71 kg/m3) of PAC-L slowly through the mud hopper

 

PAC-R, high molecular weight polyanionic cellulose, provides filtration control and supplementary viscosity in most water-based drilling fluids.

 

Control filtration rates

Retard shale swelling and disintegration

Provide supplementary viscosity in freshwater, seawater, and brine-based fluids

Add 0.5-2.0 lb/bbl (1.43-5.71 kg/m3) of PAC-R slowly through the mud hopper

 

BZ-WFD, medium molecular weight polyanionic cellulose, provides filtration control and light viscosity in most water-based drilling fluids.

 

Control filtration rates

Retard shale swelling and disintegration

Provide supplementary viscosity in freshwater, seawater, and brine-based fluids

Add 0.5-2.0 lb/bbl (1.43-5.71 kg/m3) of BZ-WFD slowly through the mud hopper
