Polyanionic cellulose PAC-HV property:
1.PAC (Polyanionic Cellulose) 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, filtrate reducer.
2.PAC is an indispensable product for drilling mud making. PAC is high purity product; the water solution of this white powder is transparent and viscid. As water-soluble polymer, it 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.
3.PAC is a good drilling mud additive and also an important material for confecting well liquid, a high mud volume product that featured high acid-resistance and salt-resistance ability. It is a good filtrate reducer with the capacity of increasing viscosity and anti-high temperature (150°C) in the freshwater, seawater, or even saturated brine well-completion liquid. It is suitable for confecting the completion fluid with these 3 kinds of water above.
1. PAC-HV is for water-based drilling fluids, which can effectively reduces 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 wide variety of fluid environment.
2. PAC-LV is for use in solids-laden, water-based drilling fluids, which can effectively reduces the filtration rate of many water-based drilling fluids, without causing significant increases in viscosity or gel strength.
3. PAC R is a cost-effective additive to reduce API filtration rate of many water based drilling fluids including freshwater, seawater, saturated saltwater and solids-free brines, native mud, flocculated mud, inhibited mud and contaminated systems.
4. PAC R increases and stabilizes viscosity to improve rheology, wellhole cleaning and suspension property by coating and encapsulating cuttings and solids of drilling fluids.
5. PAC R is effective over a wide range of pH environments. It lubricates solids in the system, improve wallcake characteristics and reduces the potential for stuck pipe.
6.Petroleum grade Product features:

Feature:
1.Polyanionic cellulose application in the drilling fluid. PAC for fluid loss inhibitors and water is ideal, PAC fluid mud can be prepared in high salt medium clay and shale inhibition dispersion and expansion of the shaft so that the pollution under control.
2,.PAC workover fluid in the application.
PAC prepared using workover fluid is a low-solid-phase, and not because of the solid layer and the blocking of the infiltration capacity of the production would not be harmful to the production floor; and the loss of low water, so that production level to reduce the amount of water, and access to water emulsion will be formed by blocking phenomenon Township.
PAC prepared using workover fluid to provide hydraulic workover other advantages not available.
Production level to protect against permanent damage;
Clean the hole with a carrying capacity, and the maintenance of boreholes to reduce the workload;
Resistance to water and sediment have the ability to infiltrate and few foaming;
Can be stored or transferred between the wells and wells, and workover fluid mud than the average and low cost.
3. PAC in the fracturing fluid applications.
PAC prepared by fracturing fluid capability 2% KCI solution (the preparation of the fracturing fluid must be added) and dissolution performance, ease of use, you can Site preparation, and gel fast, strong ability to carry sand. Osmotic pressure in the formation of low
Features
It can improve the rheological properties, help to effectively encapsulate drilling cuts, and inhibit mud yielded by soil.
It has a strong capability of resisting salt, calcium and magnesium. And it can be applied in fresh water, seawater, saturated salt water and saltwater for completion drilling fluids;
It can be applied in super-deep wells because it can stand 200°C;
It can effectively inhibit shale being dispersed and stabilize the borehole.
It can match with other agents well.
It can effectively reduce viscosity and filtration loss and its dosage is few.
It can be applied in various drilling fluids for fresh water, salt water, saturated water and seawater.
It has a thermal stablility with standing 150℃.
It can match with other agents so that it can be applied in various water base completion fluids.
It is not toxic and biodegradable, which helps to protect environment.
