6. Field Case Summary
Gulf of Mexico Deepwater Well: Fumed silica (2%) in a synthetic-based fluid eliminated barite sag at 150°C, saving $500K in non-productive time.
Kuwait HPHT Well: Reduced fluid loss by 40% and cut lost circulation incidents by 60%.
Conclusion
Fumed silica A-200 enhances drilling fluid performance by stabilizing rheology, preventing sag, and reducing fluid loss, especially in HPHT and challenging formations. Its nano-scale reactivity and robust thermal stability make it a critical additive for modern drilling operations. For implementation, collaborate with drilling fluid engineers to optimize dosage and dispersion protocols.
