Sulphonated Asphalt for Drilling Fluid

Sulphonated Asphalt Supreme

Shale Inhibitor

SOL SulphoSol Super is a high-performance sulphonated asphalt (supreme grade) designed for use in oil-based drilling fluid (OBM) systems, where effective fluid loss control, emulsion stability, and wellbore integrity are critical.

Formulated with advanced sulphonation technology, SOL SulphoSol Super enhances the sealing properties of oil-based mud systems by forming a thin, low-permeability filter cake. This helps reduce filtrate invasion, improve wellbore stability, and minimize formation damage in challenging drilling environments.

In OBM formulations, the product works synergistically with emulsifiers and other additives to strengthen emulsion structure, improve fluid stability, and maintain consistent rheological properties. It also contributes to improved lubrication, reducing torque and drag and supporting efficient drilling performance.

SOL SulphoSol Super is highly effective across a wide range of drilling conditions, including high-pressure high-temperature (HPHT) wells and deep drilling operations. Its robust performance ensures reliable results in both onshore and offshore environments.

Designed for global oilfield applications, SOL SulphoSol Super delivers consistent and dependable performance in modern oil-based drilling fluid systems.
