Oil used CarboxyMehtyl Cellulose (CMC)

Oil used CarboxyMehtyl Cellulose (CMC) is often mixed with HEC and PAC for the oil field.

Oil used CarboxyMehtyl Cellulose (CMC)

Petroleum grade Product features:

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 volum, reduce filteration loss .

6, has excellent performance in drilling of oil .
