Abstract: A method for mineral oil production by means of CO2 flooding, in which liquid or supercritical CO2 and at least one alk(en)yl polyglucoside are injected through at least one injection well into a mineral oil deposit and mineral oil is withdrawn from the deposit through at least one production well. The alk(en)yl polyglucoside is preferably dissolved in the CO2 phase. A method for mineral oil production by means of CO2 flooding, in which mixtures of the alk(en)yl polyglucosides with alk(en)yl polyalkoxylates or anionic surfactants are used.
