Ultra-High Temp Salt-Resistant Fluid Loss Reducer

Solving fluid loss in ultra-deep “three-high” wells
URFK resists 230°C+ and saturated salt, forms protective film on clay, reduces HTHP fluid loss to ≤23ml.
Ideal for deep/ultra-deep wells with high temp/pressure/salinity.

Main Advantage & Solution

1: “Three-high” (High Temp/High Pressure/High sustainbility) conditions cause additive failure;
Solution: Withstands 230°C+ and saturated salt, stable in extreme downhole environments.
2: Clay hydration swelling leads to wellbore instability;
Solution: Adsorbs on clay surfaces to form protective film, inhibits hydration/dispersion.
3: Mud suspension failure causes cuttings deposition;
Solution: Branched structure forms “weak gel” network, enhances suspension stability.
