PAC-LV (Low Viscous Polyanionic Cellulose)

Introduction

PAC-LV is high-quality Polyanionic Cellulose Polymers. It is used in most water-based drilling fluids including fresh water, seawater and brine up to 300°F. PAC-L has a minimal increase in rheology, is non-toxic and does not require a biocide. PAC-L is can also encapsulate solids to control dispersion of active shale.

Applications/Functions

Control filtration rates with minimal increase in rheology  

Aids in the formation of a tough, thin filter cake to minimize the potential for differential sticking

Advantages

Temperatures stable up to 300°F

No fermenting, no biocide needed

Effective in fresh water, seawater and brine fluids

Functions in all pH range

Produces thin, slick, tough filter cake

Inhibit hydratable, swelling shales

Environmentally compatible

Typical Properties
