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.

Abstract: The invention relates to a method for oil recovery, according to which an aqueous formulation comprising at least one water-soluble, hydrophobically associating copolymer is forced through at least one injection well in an oil deposit and crude oil is extracted from the oil deposit through at least one production well, said deposit being at a temperature of between 35°C and 120°C, preferably between 40°C and 90°C. The water-soluble, hydrophobically associating copolymer comprises at least acryl amide or derivatives thereof, a monoethylenically unsaturated monomer having anionic groups and a monoethylencally unsaturated monomer that can cause the association of the copolymer.

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.
