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: 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.
