1. Drilling Fluid Rheology Control
CNOOC South China Sea Platform Project: Hydrophilic fumed silica was added to HPHT wells to enhance the high-temperature suspension stability of the drilling fluid.
2. Oilwell Cement Slurry Optimization
Schlumberger Saudi Project: Fumed silica was added to high-density cement slurries to improve rheological properties and prevent cement settling.

Halliburton Xinjiang Project: Hydrophilic fumed silica helped form a uniform slurry, enhancing channeling control performance.
3. Completion Fluid Stabilization
Brazil Offshore Deepwater Field: A-200K was used to maintain uniform barite distribution in the completion fluid, thereby extending the operational window.
CNOOC East China Sea Project: A-200K was applied in KCl-based completion fluid within a closed wellbore to prevent fluid loss and formation contamination.
