CG610 Fluid Loss Additive for Oil Well Cement
Product Overview
CG610 is a synthetic polymer-based Fluid Loss Additive designed for medium and high-temperature oil well cementing applications. It effectively reduces fluid loss from cement slurries while maintaining excellent slurry stability and workability. As one of the high-performance Oil Well Cement Additives developed by Kelioil, CG610 is widely used in deep well and ultra-deep well cementing projects.
This Cementing Additive can be applied in lightweight, normal-density and heavyweight cement slurry systems. It performs effectively in fresh water, salt water and saturated brine systems, making it suitable for challenging cementing environments where conventional fluid loss additives may struggle to maintain performance.
With excellent compatibility, high-temperature resistance and reliable fluid loss control, CG610 helps improve cement sheath quality, reduce formation damage risks and enhance long-term zonal isolation.
