Unitedhb Group (www.unitedhb.com) produce full range of CMC as additive of drilling fluids.

CMC  is effective water loss controller and viscosifier with high mud yield to reduce API filtration rate, and it is resistant to salt, base and moisture, compatible with sea water and saturated brine. So, it is widely used as filtration  reducer.

CMC also is used in fracturing fluid, and well cementing fluid as fluid loss controller and viscosifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency. 

Our CMC properties for oil industry:

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

2, high transparency, viscosity and water loss can be controlled.

3, suitable for fresh water, sea water, saturated brine slurry .

4, stabilize soft soil structure,prevent collapse of wall of a well .

5, can improve mud-making volume,reduce filtration loss .

6, has excellent performance in oil drilling .

7, effective in low concentration.
