EPISOL

a fluid loss agent for oil-based drilling systems, compounded from oil-soluble polymers and modified asphalt. This product can effectively control the fluid loss of oil- based drilling fluids, especially at high temperature and pressure. EPISOL can also increase drilling fluid blocking and lubricating performance, improve well bore stability. EPISOL can be used in diesel-based, white oil-based, and synthetic-based drilling fluids at the same time and is less affected by different types of surfactants in the system.

Application

• Fluid loss agents can effectively reduce the amount of filtration. Meanwhile, it can also help increase drilling fluid blocking and lubricating performance, as well as improve wellbore stability. EPISOL can be applied at temperatures up to 220°C with great performance on effective
