    Abstract: The present invention relates to a process for mineral oil extraction by means of Winsor type III microemulsion flooding, in which an aqueous surfactant formulation comprising at least three ionic surfactants which are different with regard to the alkyl moiety (R1)(R2)—CH—CH2— and are of the general formula (R1)(R2)—CH—CH2—O-(D)n-(B)m-(A)l-XYa−a/bMb+ is injected through injection boreholes into a mineral oil deposit, and crude oil is withdrawn from the deposit through production boreholes. The invention further relates to surfactant formulations of ionic surfactants of the general formula.
