CPC classification number: C09K8/584
Abstract: A process for mineral oil production, especially Winsor type III microemulsion flooding, in which an aqueous surfactant formulation is used which comprises at least one alkyl polyalkoxysulphate containing propoxy groups, and also at least one further, different surfactant, is forced through injection wells into a mineral oil deposit, and crude oil is removed from the deposit through production wells. The alkyl polyalkoxysulphate containing propoxy groups here is prepared by sulphating an alkoxylated alcohol, the alkoxylated alcohol being prepared by alkoxylating an alcohol using double metal cyanide catalysts or double hydroxide clays.
