Specification :

This product is a viscosifier with anti -salt performance, which also is a filtrate reducer, belong to be an anionic cellulose ethers.

ADVANTAGES:
1. Extended maintenance cycle of the mud.
2. Can be soluble in water, good thermal stability, and salt-tolerance, strongly anti-bacterial.
3. Good filtration, inhibition and resistant high temperature.
4. Can be prepared for work over drilling fluid and fracturing fluid
5. After adding CMC into the mud, the drilling rig can get low zero gel so that the mud release the gas, which is easy to remove the solid phase.

USAGE AND DOSAGE:
The product can be used alone, also can be combined with other products.
The dosage is 0.5% ~ 1%, also can be added in accordance with the actual situation at the scene. Adding slowly while stirring, We can also be added with aqueous solution.
