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: Compositions and methods of synthesis of anionic surfactants by alkoxylation of a Guerbet alcohol (GA) having 12 to 36 carbon atoms using butylene oxide, and optionally propylene oxide and/or ethylene oxide followed by the incorporation of a terminal anionic group are described herein. The GA of the present invention is made by a facile and inexpensive method that involves high temperature base catalyzed dimerization of alcohols with 6 to 18 carbon atoms. The large hydrophobe ether surfactants of the present invention find uses in enhanced oil recovery (EOR) applications where it is used for solubilization and mobilization of oil and for environmental cleanup. Further, the hydrophobe alkoxylated GA without anionic terminal group can be used as an ultra- high molecular weight non-ionic surfactant.

Abstract: Se describe el uso de ácidos aromáticos libres que contienen por lo menos dos sistemas de anillo aromático o por lo menos dos funciones ácidas, y/o sales de los mismos, para influenciar las formaciones rocosas en la explotación de depósitos subterráneos de petróleo mineral y/o de gas natural. Los ácidos libres se utilizan en particular para influenciar y especialmente controlar el flujo de ácido dentro de las formaciones rocosas en los así llamados métodos de acidificación. Las sales adecuadas de dichos ácidos aromáticos sirven para reducir la permeabilidad de la roca y en particular reducir el flujo de entrada de agua dentro del agujero del pozo. Además de este uso, también se reivindican los métodos correspondientes.
