Cement Lost Circulation Proof Admixture

Brief Introduction:

It can form fibrous network across lost circulation formations

CELO-02 is a kind of material with fiber with good adaptability in slurry. It can form fibrous network across lost circulation formations. The product can enhance set cement flexibility, prevent cement shrinkage and increase the slurry thickness a little, with no other side effect. CELO-02 can be premixed with cement or added to the slurry directly.

 

USAGE

Service Temperature Range:                        ≤160.00C

Dosage:                                                1.5-3.0% (BWOC)

 

PACKAGING

Packaged in 20kg sacks or based on the requirement of customs.

 

OTHERS

Refer to MSDS and CEMENTING MATERIAL MANUAL when deposit or use CELO-02.
