A small amount of Polyanionic Cellulose can replace a lot of clay and this kind of mud can reduce the difficulties resulting from encountering CaSO42H20 or CaSO4 salt belt during drilling process. However, PAC applies to the mud with larger proportion, can reduce the fluid loss but have little effect on the viscosity. In use, Polyanionic
Polyanionic cellulose regular grade (PAC R or PAC HV) is a premium grade modified cellulose with high viscosity and high molecular weight which can be used as a viscosifier and fluid loss control additive in water-based drilling mud systems.PAC R can provide excellent viscosity and reduce API filtration rate for oil well drilling fluids.API 13A and OCMA grades polyanionic cellulose (pac) in
AquaPAC™ polyanionic cellulose is of premium quality and cost-effective and provides outstanding fluid-loss control properties, shale inhibition and salt tolerance. It is useful for water-based drilling fluids as well as in low-density brines.
6. Environment friendly PAC LV HV R Drilling Fluid Mud Polyanionic Cellulose Polymer Applications in Drilling Fluid 1. Protect the wall of oil well, prevent mud flowing away and carry crumbs. 2. Protect drilling bit and increase drilling speed. 3.
Sodium Carboxymethyl Cellulose (CMC) and Polyanionic Cellulose(PAC) can be used in drilling fluid, fixing fluid and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer and rheology controller; in fixing fluid, it is used to control fluid viscosity, suspend heavy objects and avoid fluid loss; also in fracturing fluid, it is used to carry stuffing and avoid fluid loss.

Structural Formular: Property: PAC is a kind of nonionic cellulose ether featured the properties of high purity, high DS, particularly high viscosity or low viscosity. These products are demi-natural polymer additive, thickening agent
Polyanionic Cellulose is more suitable for offshore drilling and the functions of Polyanionic Cellulose in drilling fluid are listed as below. 1). The drilling mud is the suspended matter of solids in the aqueous solution, and the same as other colloidal suspension dispersions, so has a certain life period.
pac is a cellulose derivative product, white to creamish coloured free flowing fine powder / granules available as pac- lv and pac-r. pac -lv is a short chain polymer and it is used as a filtration control agent in all types of water base drilling mud. pac-r is a long chain polymer of high molecular weight, readily
There are different types of polymers used in drilling fluid, both organic and inorganic materials are used in drilling fluids depending on the specific function required.

These products are demi-natural polymer additive, thickening agent, filtrate reducer.
Industrial grade polyanionic cellulose(PAC) for deep water drilling. PAC is a non-ionic cellulose ether, which has the characteristics of high content and high degree of substitution. The viscosity can be adjusted according to requirements. It is a semi-natural polymer additive, thickener and fluid loss reducer. PAC plays an
PAC LV (also PAC L) is a premium grade purified low viscosity polyanionic cellulose (PAC) for oil and gas drilling which is designed to use as a fluid-loss control additive in freshwater, saltwater, KCl, and seawater drilling mud systems. It has low molecular weight which is essentially not a viscosifier and can be help form a thin and tough filter cake so as to minimize differential sticking
In this study, the effects of Polyanionic Cellulose Polymer (PAC) on water base drilling fluids were studied. From the results:- The raw clay from study area is near to Ca bentonite. Adding PAC improved water base drilling fluids in different degrees of efficiency. The drilling fluids reach API specification for
