Abstract: The invention relates to a method for producing tertiary crude oil with the aid of a surfactant mixture and/or to the use of a surfactant mixture for producing tertiary crude oil by means of Winsor type III microemulsion flooding, in which a surfactant mixture is forced through at least one aqueous injection well into a mineral oil deposit and crude oil is removed from the deposit through at least one production well. The surfactant mixture comprises, for lowering the interfacial tension between oil and water to

Abstract: Proceso para la extracción de petróleo, especialmente, la inundación con microemulsionesWinsor tipo III, en el que se inyecta una formulación acuosa de surfactante, que comprende por lo menos un alquilpolialcoxisulfato que contiene grupos propoxi, así como por lo menos otro surfactante diferente del primero, por pozos de inyección en un yacimiento de petróleo y se extrae el petróleo crudo del yacimiento por pozos de producción. El alquilpolialcoxisulfato que contiene grupos propoxi se obtiene aquí por sulfonación de un alcohol alcoxilado, cuyo alcohol alcoxilado se prepara por alcoxilación de un alcohol usando catalizadores de cianuro de metal doble o arcillas de hidróxido doble.

Abstract: Process for tertiary mineral oil production in which an aqueous injection fluid comprising at least a water soluble polyacrylamide-(co)polymer dissolved in the aqueous fluid is injected into a mineral oil deposit and the aqueous injection fluid is prepared by mixing a liquid dispersion polymer composition comprising particles of polyacrylamide-(co)polymers dispersed in an organic, hydrophobic liquid with an aqueous fluid. Preferably, the process is carried out on an off-shore production site.
