It is specially designed for lightweight and normal density cement slurry system with high dispersity.
Enhance the stability of the suspension, maintains the liquidity of the cement slurry, and prevents sedimentation.
The thickening time decreases with increasing temperature, and the compressive strength of the set cement develops rapidly.
Help control gas migration during the setting of the cement slurry.
It is suitalbe for use in fresh water, seawater, and slurry containing 2% CaCl2.
It is recommended for use below temperature of 180℃(356℉, BHCT).
Compatible with other additives.
Summary
The fluid loss additive is a synthetic polymer that effectively reduces water loss from the slurry to the porous formation during the cementing process.
It is specially designed for lightweight and normal density cement slurry system with high dispersity.
Enhance the stability of the suspension, maintains the liquidity of the cement slurry, and prevents sedimentation.
The thickening time decreases with increasing temperature, and the compressive strength of the set cement develops rapidly.
