Laboratory Development and Application of a Synthetic Oil ...
A successful OB/SBM filter cake treatment must break the mud's interfacial rheological properties, act as a demulsifier to break the water-in-oil emulsion, and break the filter cake's bond with the wellbore wall. A synthetic oil/surfactant-based fluid system has been developed to cleanup OB and SB mud filter cakes.
