摘要： A process for mineral oil production, in which an aqueous formulation comprising at least one water-soluble, hydrophobically associating copolymer is injected through at least one injection borehole into a mineral oil deposit, and crude oil is withdrawn from the deposit through at least one production borehole, wherein the water-soluble, hydrophobically associating copolymer comprises at least acrylamide or derivatives thereof, a monomer having anionic groups and a monomer which can bring about the association of the copolymer, and water-soluble, hydro-phobically associating copolymer which has a low shear degradation and is suitable for execution of the process.
