Research topic: “Wettability Alteration Induced by Chemical Agents at Elevated Temperature and Pressure"


The focus of this new research is to further study wettability alteration capacity of previously screened modifiers under both hot water condition with higher temperature and steam condition. Interfacial tension between oil and modifier solution are measured. Contact angle measurement is extended to steam and hot water conditions and the wettability alteration process is tested using capillary imbibition method at high-pressure and high-temperature conditions. Atomic force microscopy will help to give visual data illustrating the deposition of the chemicals on the surface of mica and calcite substrates.
