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 a constant load shear cell and a method for constant loading of a magnetorheological fluid in a constant load shear cell. The constant load shear cell comprises a rotatable shaft (1), to which a rotor plate (2) is fixed. A first gap (5), for accommodating a magnetorheological fluid, is formed between a first side (3) of the rotor plate (2) and a first shear surface (4). A second gap (8), for accommodating the magnetorheological fluid, is formed between a second side (6) of the rotor plate (2) facing away from the first and a second shear surface (7). The constant load shear cell further comprises at least one magnet (9) for generating a magnetic field in the first and second gaps (5, 8).
