Abstract: The invention relates to a method for producing mineral oil by means of Winsor Type III microemulsion flooding, wherein an aqueous surfactant formulation which comprises, in relation to the alkyl part (R1)(R2)-CH-CH2-, at least three different ionic surfactants of general formula (R1)(R2)-CH-CH2-0-(D)n-(B)m-(A)I-XYa- a/b Mb+, is pressed though injection wells into a mineral oil deposit and crude oil is extracted from the deposit via production wells. The invention also relates to surfactants formulations of ionic surfactants according to the general formula.

IPC: C09K8/588
Abstract: The invention relates to a method for producing tertiary crude oil with the aid of a surfactant mixture and/or to the use of a surfactant mixture for producing tertiary crude oil by means of Winsor type III microemulsion flooding, in which a surfactant mixture is forced through at least one aqueous injection well into a mineral oil deposit and crude oil is removed from the deposit through at least one production well. The surfactant mixture comprises, for lowering the interfacial tension between oil and water to
