Abstract : This work deals with the understanding of interactions between in situ or indigenous surfactants and added synthetic surfactants for Enhanced Oil Recovery EOR. Heavy crude oils contain amphiphilic molecules, such as asphaltenes and naphthenic acids, which are natural surfactants. During an EOR operation, pH influences the ionization of acidic and-or basic species of crude oil making them more hydrophilic that increases their affinity for the interface.In this study, we showed that there is a strong interaction between a sulfonated anionic surfactant SDBS and in situ surfactant of an acidic heavy oil. Ultra-low interfacial tensions
