CG212 Anti-Settling Fluid Loss Additive for Lightweight Cement Slurry Systems
Product Overview
CG212 is a high-performance Anti-Settling Fluid Loss Additive specifically developed for lightweight cement slurry systems and highly dispersed normal-density cement slurries. It effectively controls fluid loss while significantly improving slurry suspension stability, helping prevent particle settlement and density segregation during cement placement.
As one of the advanced Oil Well Cement Additives developed by Kelioil, CG212 provides excellent fluid loss control, anti-settling performance and gas migration resistance. The product is particularly suitable for lightweight cement systems where slurry stability is critical to achieving successful zonal isolation.
CG212 can be applied in fresh water and half-saturated salt water systems and is suitable for medium and high-temperature cementing applications up to 180°C (356°F BHCT).
