Abstract: Use of a mixture comprising a surfactant and a cosurfactant in the form of an aqueous solution for flooding underground deposits of hydrocarbons for mobilizing and recovering the hydrocarbons from the underground deposits, the cosurfactant being a substance or a group of substances selected from the following list: an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, the side chains differing from one another and/or the side chains differing from the backbone in their amphiphilic character, an amphiphilic polymer having one or more hydrophobic subunits [A2] based on a polyisobutene block, at least 50 mol % of whose polyisobutene macromolecules have terminally arranged double bonds, and one or more hydrophilic subunits [B2], or an amphiphilic polymer having the general structural formula

Abstract: The invention relates to the use of a mixture containing a surfactant and a cosurfactant in the form of an aqueous solution for flooding underground hydrocarbon fields in order to mobilise and extract hydrocarbons therefrom, wherein the cosurfactant is embodied in the form of a substance or the group of substances selected from an amphiphilic comb polymer comprising a backbone which is provided with two or more side chains which differ from each other and/or from the backbone in terms of the amphiphilic character thereof, the amphiphilic polymer comprises one or several hydrophobic sub-groups [A2] based on a polyisobutene block, wherein at least 50 Mol % of polyisobutene macromolecules have terminal double bonds and one or several hydrophobic sub-groups [A2] or an amphiphilic polymer of a general structural formula (I).
