Sulfonated Asphalt
Catalog NO.: AIMRSE-CHM-ADD-066 Manufacturer PN: CHM-BIT-SUL
• Thermal stability exceeds 200°C; prevents rock formation collapse; significantly improves system lubricity; easily disperses in water-based or oil-based muds; helps form a thin and tough mud cake.
Effectively reduces high-temperature, high-pressure filtrate loss in water-based and oil-based muds, reinforces wellbore walls, and provides excellent collapse prevention.
This sulfonated asphalt is a loss control agent suitable for both oil-based and water-based drilling fluid systems. It forms a thin yet resilient mud cake, enabling hydrophobic particles to effectively seal microfractures, thereby preventing rock hydration, reducing cuttings erosion, and providing collapse resistance. The product exhibits strong contamination resistance, a broad pH applicability range, and temperature tolerance exceeding 200°C.
