description | Process for enhanced oil recovery employing an aqueous solution comprising at least one linear or structured water-soluble copolymer obtained by polymerization: of at least 10 mol % of 2-acrylamido-2-methylpropanesulfonic acid monomer in the free acid and/or salified form, of at least 10 mol % of at least one comonomer chosen from the group consisting of acrylamide, N-vinylpyrrolidone (NVP) and acrylamide-derived monomers of formula (I): in which: R=H or CH3 or CH2COOR′, where R′ is an alkyl comprising at most 3 carbon atoms, A is an N heterocycle comprising, in its ring, from 4 to 6 carbon atoms and optionally an ether functional group or a ketone functional group. |
