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
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

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
GMC PAC R polyanionic cellulose controls fluid loss in freshwater, seawater, KCl, and saltwater drilling fluid systems. GMC PAC R is a regular techgrade quality PAC, useful in controlling filtration and increasing rheology in all types of water, but is particularly effective in saltwater brines.
Product Description. Polyanionic Cellulose PAC. Known for its low viscosity level, the Polyanionic Cellulose PAC has low molecular weight and this polymer has been specially formulated for water based drilling fluids with solid laden properties.The unique composition of this product drastically lowers filtration rate of several water based drilling fluids without raising their gel
PAC HV is a high quality Polyanionic Cellulose Polymer. It is a water based filtration control agent which also provides viscosity and controls fluid loss. Application: PAC HV is a cost effective means of controlling fluid loss and increasing viscosity and it improves the quality of the filter cake in water based drilling systems.
Polyanionic Cellulose Polymer (PAC) is used for Oil Well Drilling to give suitable flow properties to the drilling muds.PAC also improves the water retention of muds and prevents excessive penetration of drilling liquid into the immediate surroundings. PAC can be added to control filtration of water-base muds without a severe increase in the
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.
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.
M-I PAC R technical-grade polyanionic-cellulose filtration-control additive. M-I PAC R additive is a regular tech-grade quality PAC, useful in controlling filtration and increasing rheology in all types of water but is particularly effective in saltwater brines.and saltwater drilling fluid systems. It aids in the formation of a tough, thin
Polyanionic Cellulose Low Viscosity manufactured by Global Drilling Fluids and Chemical Limited helps to control fluid loss in Fresh water , Sea water ,KCL and Salt mud systems and reduces the potential for deferential sticking . It resists bacterial attach thus eliminating the need for preservatives.

Oil Drilling Polyanionic Cellulose PAC FOB Reference PriceAs one kind of water-soluble polymer, PAC dissolves immediately in cold/hot water and can be used as a thickening agent, rheology controller, bond, stabilizer, colloid protector, suspending agent, and filtrate reducer. PAC is a good drilling mud additive and also is an important
PAC-HV is a cellulose derivative product, white to creamish coloured free flowing fine powder. It is used for water-based drilling fluids, which can effectively reduce the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in
A cellulose derivative similar in structure, properties and usage in drilling fluids to carboxymethylcellulose. PAC is considered to be a premium product because it typically has a higher degree of carboxymethyl substitution and contains less residual NaCl than technical grade carboxymethylcellulose, although some PACs contain considerable NaCl.
