    Abstract: A method for recovering petroleum from underground petroleum reservoirs, wherein an aqueous formulation containing at least one water-soluble hydrophobically associating copolymer is injected via at least one injection bore into a petroleum reservoir at a reservoir temperature ranging from 20°C to 120°C, and crude petroleum is extracted from the reservoir via at least one production bore; the water-soluble copolymer contains at least acrylamide or derivatives thereof and a mixture containing at least two amphiphilic macromonomers.

    Abstract: Un proceso para la producción de petróleo, en donde una formulación acuosa que comprende al menos un copolímero hidrosoluble hidrofóbicamente asociado se inyecta a través de al menos una perforación de inyección en un depósito de petróleo y el petróleo crudo se extrae del depósito a través de al menos una perforación de producción, en donde el copolímero hidrosoluble asociado hidrofóbicamente comprende al menos acrilamida o sus derivados, un monómero que tiene grupos aniónicos y un monómero que puede llevar a cabo la asociación del copolímero y copolímero hidrosoluble hidrofóbicamente asociado que puede tener una degradación de bajo cizallamiento y es apropiado para la ejecución del proceso.

    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.
