Abstract: The invention relates to a surfactant mixture containing, in relation to the hydrocarbon part (R1)(R2)-CH-CH2- at least three different ionic surfactants of general formula (I), wherein R1, R2, A0, k, X, o, Y, a, b, M have the meaning indicated in the description and the claims. The invention further relates to the use and production thereof and to aqueous surfactant formulations containing the mixtures and to a method for producing mineral oil by means of Winsor type III micro emulsion flooding, in which the aqueous surfactant formulation is forced through injection wells into a mineral oil deposit and the crude oil is removed from the deposit through production wells.

Abstract: Method of fracturing subterranean formations using aqueous compositions comprising at leastan aqueous base fluid, proppants, a viscosifier, at least one flowback aid and removing at least a portion of the aqueous fracturing fluid from the formation after fracturing. The flow- back aid is selected from the group of alkyl or alkenyl polyglucosides, carboxylated alkyl or alkenyl polyglucosides and alkoxylated branched alcohols.

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.

Abstract: The present invention relates to a method of producing mineral oil from underground mineral oil deposits, in which an aqueous formulation comprising at least a mixture of alkyl ether carboxylate and corresponding alkyl ether alcohol, where the alkyl ether carboxylate has been prepared from the alkyl ether alcohol and the molar ratio in the mixture of alkyl ether carboxylate:alkyl ether alcohol is from 51:49 to 92:8, is injected through at least one injection well into a mineral oil deposit, where the deposit has a deposit temperature of 55°C to 150°C, a crude oil having more than 20° API and a deposit water having more than 100 ppm of divalent cations, and crude oil is withdrawn through at least one production well from the deposit. The invention further relates to the preparation of the mixture and to a concentrate comprising the mixture.

Abstract: Se describen composiciones y métodos de síntesis de tensioactivos aniónicos mediante la alcoxilación de un alcohol de Guerbet (GA) que tiene de 12 a 36 átomos de carbono utilizando óxido de butileno, y opcionalmente oxido de propileno y/u óxido de etileno, seguida por la incorporación de un grupo aniónico terminal como se describe en este documento. El GA de la presente invención es preparado por un método fácil y económico que involucra una dimerización de alcoholes con 6 a 18 átomos de carbono catalizada por una base, a alta temperatura. Los tensioactivos éter hidrófobos grandes de la presente invención encuentran usos en las aplicaciones de recuperación mejorada de petróleo (EOR) en donde se utiliza para la solubilización y movilización del petróleo y para la limpieza ambiental. Además, el GA alcoxilado hidrófobo sin grupo aniónico terminal se puede usar como un tensioactivo no iónico de ultra alto peso molecular.
