Unitedhb Group（www.unitedhb.com) produce full range of poly anionic cellulose(PAC) for drilling fluid, workover fluid, fracturing fluid complying API 13A. 

Usage:

1. Application of PAC in drilling fluid: PAC is a kind of ideal inhibitor and fluid loss additive. Mud fluid prepared by PAC preparation can inhibit the dispersion and expansion of clay and shale in high salt medium so that the sidewall contamination can be controlled.

2. Application of  PAC in workover fluid: The workover fluid prepared by PAC is of the advantages   that other do not have: 1) preventing the production zone from permanent damage; 2) having the carrying capacity of cleaning borehole, and reducing the workload of maintaining wellbore; 3) having the ability to resist water and sediment infiltration and rarely blistering;

3. PAC's role in the fracturing fluid: the fracturing fluid prepared by PAC can resist 2% KCL solution (which must be added in the fracturing fluid preparation) and has good  solubility. It is easy to use, can be prepared on site; and its gel-forming speed is good with strong sand carrying ability. When used in the stratum of low osmotic pressure, its fracturing effect is more remarkable.

Our PAC have features as:

1, High degree of substitution,good uniformity of substitution.

2. can increase and stabilize the viscosity

3. Stabilize soft soil structure;prevent collapse of wall of a well.

4. Suitable for fresh water, sea water, saturated brine slurry.

5. Improve mud-making volume,reduce filtration loss.

6. Has excellent performance in oil drilling.

We produce full range of  Polyanionic cellulose for oil industry:

PAC LV:        Low viscosity

PAC R:           Regular viscosity

PAC HV         Fltration reducer

Note: can be customized produced according to the demands.
