In this study, an asphaltic Turkish crude oil was treated with alkali solution (NaOH) at different concentrations to simulate an alkali EOR technique. IFT (interfacial tension) measurements were carried out by ring method and the yields of asphaltene is precipitated after the process. Thermal properties of these asphaltenes were investigated by thermal analysis methods (thermogravimetry, TG/DTG and differential scanning calorimeter, DSC) to infer the possible changes in the asphaltene molecules and their behavior during refinery or fuel purposes.
