Polyanionic Cellulose (PAC) Water-Based Drilling Fluid Additive is a modified natural cellulose polymer, which provides filtration control in most water-based drilling fluids.

When PAC additives are added to drilling mud, they produce a drilling mud system suitable for drilling in sandy formations. PAC additives can be added to vegetable oil or mineral oil to provide an oil-based fluid suspension that can be poured directly into the drill string. PAC additives are also used in air/gel foam drilling.

Applications of polyanionic cellulose (PAC)

Provide filtration control in freshwater or saltwater-based drilling fluids

Improve wellbore stability in water-sensitive formations

Minimize rotational torque and circulating pressure

Improve hole cleaning and core recovery

Harden foam to improve cuttings transport in air/foam drilling

Reduce air demand, wellbore velocity and wellbore annular pressure in air/foam drilling

Advantages of polyanionic cellulose (PAC)

Applicable to freshwater, saltwater and saltwater-based drilling fluids

A small amount can effectively control filtration

Non-fermentation

Can be mixed with other drilling fluid additives

Resistant to harsh environments and pollutants

Simple to use, add slowly and evenly to the entire circulation system in the vortex of a high-speed agitator.
