It effectively reduces the thickening time at low temperature while maintaining good fluid loss reduction performance.
The transition time of thickening and setting performance is short.
Promote the early strength development of setting cement at low temperature.
Could be used in normal density, low density and high density cement slurry systems.
Used below temperature of 60℃（140℉，BHCT）.
Compatible well with other additives.
Recommended dosage range is 1.2-2.5% (BWOC).
SUMMARY
CG910S product has the dual-effects of reducing fluid loss and accelerating coagulation at low temperature. It effectively shortens the thickening time at low temperature while maintaining good fluid loss reduction performance.
Dual-Action Performance: Acts as both a high-efficiency fluid loss agent and a powerful coagulation accelerator in cool environments.
Rapid Early Strength Development: Specifically designed to achieve a compressive strength of ≥5.0 MPa in just 8 hours at 40℃, allowing for faster transition to subsequent operations.
Precise Thickening Control: Shortens the thickening time ratio (≤0.6 compared to neat slurry) and ensures a very short transition period, minimizing the risk of gas or fluid channeling.
Versatile Density Range: Excellent stability across normal, low, and high-density cement systems.
Enhanced Slurry Integrity: Maintains API fluid loss ≤50 ml even while accelerating the setting process.
Used below temperature of 60℃（140℉，BHCT）.
Compatible well with other additives.
Only suitable for water mixed use.
Recommended dosage range is 1.2-2.5% (BWOC).
Optimizing Surface Casing Operations:
In surface casing or cold-well environments, traditional fluid loss additives often retard the cement, leading to excessively long Wait-on-Cement (WOC) times. CG910S solves this by bridging the gap between filtration control and rapid setting. Its ability to maintain low free fluid (≤1.4%) while promoting fast hydration makes it the premier choice for operators looking to reduce rig time without compromising safety.
