High Temp fluid loss additive

SUMMARY

CG610 fluid loss additive is a synthetic polymer which is capable of effectively reducing water loss filtering from the slurry to porous formation during cementing process.

Applicable for medium and high temperature wells. 

Slurry Density Flexibility: Effectively controls fluid loss in lightweight, normal, and high-density systems.

Unmatched Salt Tolerance: Stable performance from fresh water to fully saturated brine (NaCl)

Extreme Temperature Range: Performs reliably in BHCT up to 204.4℃ (400℉), suitable for deep and ultra-deep wells.

Compatible well with other additives.

Versatile Forms: Options include standard liquid, anti-freezing liquid (L-A) for cold climates, and concentrated powder (S) for easy logistics.

Recommended dosage is 2.0-6.0(BWOC) for liquid products, and 0.6-2.5% (BWOC) for powder product.

TYPICAL APPLICATION 

CG610 is engineered for challenging well bore environments where conventional additives fail. Its robust molecular structure ensures stable performance in the following conditions:

HPHT (High Pressure High Temperature) Wells: With a thermal stability of up to 204.4℃ (400℉), CG610 is the ideal choice for deep and ultra-deep gas and oil wells, maintaining slurry integrity under extreme bottom-hole circulating temperatures (BHCT).

High-Salinity & Salt-Saturated Formations: Perfectly suited for drilling through salt domes or using salt-saturated mixing water. It maintains excellent filtration control even when the salinity reaches saturation, preventing slurry contamination and formation damage.

Complex Density Slurry Systems: Whether you are using lightweight microsphere slurries to prevent circulation loss or high-density weighting agents for pressure control, CG610 provides consistent fluid loss properties without compromising slurry rheology.

Offshore & Arctic Operations: The CG610L-A (Anti-freezing) variant is specifically designed for cold climate logistics and offshore platforms, ensuring the additive remains pumpable and effective in sub-zero temperatures.

Gas Migration Control: By effectively reducing water loss to porous formations, CG610 helps in building a dense filter cake, which is critical for preventing gas channeling during the transition time of the cement slurry.
