Description
Sulphonated Asphalt is a chemically modified asphalt treated with sulfonating agents to make it dispersible in water-based drilling fluids. It is widely used in oilfield drilling operations to reduce filtration loss, plug micro-fractures, and inhibit shale swelling.
This product improves wellbore stability, minimizes formation damage, and enhances overall drilling efficiency, especially in troublesome shale and fractured formations.
