    Abstract: of the disclosure Aqueous surfactant formulations based on protein/fatty acid condensates and their use in crude oil production Aqueous surfactant formulations, containing a surfactant mixture composed of: a) 2 to 95 %, preferably 20 to 80 %, of a protein/fatty acid condensate obtained by reacting 1 mole of a protein of the formula in which R is the radical of an amino acid, m is an alkali metal ion or ammonium ion and n is a number from 0 to 50, preferably from 2 to 33, with 0.5 to 4 moles of a fatty acid chloride of the formula R1-CO CL in which R1 is C7-C21-alkyl or C7-C21-alkenyl, b) 5 to 98 %, preferably 20 to 80 %, of a hydrocarbon-sulfonate and c) 0 to 80 % of an alkoxylated surfactant. These surfactant mixtures are used in surfactant flooding for increasing the yield in crude oil production.

    Abstract: Surfactant mixtures made from 5 to 80% by weight of an ether sulfonate, 5 to 80% by weight of an alkyl or alkylphenol polyglycol ether and 10 to 80% by weight of an alkanesulfonate, petroleumsulfonate or alkylbenzenesulfonate. This combination of surfactants produces stable, aqueous solutions or dispersions which are highly suitable for surfactant flooding in tertiary oil recovery since these aqueous surfactant solutions or dispersions form microemulsions with the oil even at high salinities.

    Abstract: Aqueous surfactant compositions containing a surfactant mixture of a) 55 to 85% by weight of an alkanesulphonate, petroleumsulphonate, olefinsulphonate or alkylbenzenesulphonate having a mean molecular weight of 280-400 and b) 15 to 45% by weight of an ether sulphonate of the formula RO(AO)mA'SO3M where R is C6-C20-alkyl or a phenyl group which is substituted by one to three alkyl groups having a total of 6 to 20 carbon atoms, A is a C2H4 or C3H6 group or a mixture of the two groups, A' is -C2H4- or -C3H6-, m is a number of 3 to 25, and M is an alkali metal atom or ammonium. These surfactant mixtures are suitable for tertiary oil recovery in combination with specific salt-stable copolymers based on polyarylamide. They form stable solutions or dispersions with highly saline water.

    Abstract: In surfactant mixtures consisting of 5 to 80 % by weight of an ether-sulphonate, 10 to 90 % by weight of an alkanesulphonate, petroleumsulphonate or olefinsulphonate and 2 to 40 % by weight of a fatty alcohol or of an alkyl polyglycol ether or alkylphenyl polyglycol ether, the alkylene oxide content in the alkyl polyglycol ether or alkylphenyl polyglycol ether should be smaller than in the ether-sulphonate. This combination of surfactants gives stable aqueous solutions or dispersions in substances which are very suitable for surfactant flooding in tertiary crude oil recovery, since these aqueous surfactant solutions or dispersions form microemulsions with the oil even at high salinities and high temperatures. The components of the mixture are adsorbed on quartz to approximately the same extent.
