PAC MUD polyanionic cellulose

A high-quality, water-soluble polymer designed to control fluid loss and increase viscosity in war-base muds.

Applications

PAC Mud controls fluid loss and provides viscosity in freshwater, seawater, KCI and salt muds. It forms a thin, resilient , low permeability filter cake which minimizes the potential for differential sticking and the invasion of filtrate and mud solids into permeable formations.

Advantages

• Effective in low concentrations for controlling fluid loss and building viscosity
• Encapsulates shale particles to inhibit swelling and dispersion
• Resists bacterial attack, requiring no biocides or preservatives
• Functions over a wide range of salinity, hardness and pH levels
• Applicable in all water-base fluids, ranging from low-solids, non-dispersed polymer systems to high-density, dispersed systems.

Method of Addition

PAC Mud is effective in low concentrations, with the normal fluid-loss treatment ranging from 0.25 to 1 lb/bbl (0.71 to 2.85 kg/m). PAC Mud should be added slowly at the hopper or mixing system to present clumping or “fish eyes”.

Packaging and Storage

Pac Mud (9410019) is packaged in 50 lb/22.7 kg multi-walled bags. Pac Mud (9410052) is packaged in a 28.7 lb/13 kg pail.
