description The present invention concerns a method for inhibiting the permeation of water in an extraction well of a hydrocarbon fluid from an underground reservoir which comprises: a) injecting into said reservoir, at least one treatment fluid comprising at least one emulsion or one dispersion in an organic solvent of at least one copolymer from: - a first monomer selected from an acrylic monomer or methacrylic monomer, and - a second monomer comprising at least one ethylene unsaturation and at least one polyoxyethylene chain. The present invention also concerns emulsions and dispersions of copolymers usable in the above-mentioned method.
