Abstract: A method for inhibiting the permeation of water in an extraction well of a hydrocarbon fluid from an underground reservoir is described. The method includes the injection of at least one treatment fluid into the underground reservoir. The treatment fluid contains at least one emulsion or dispersion in an organic solvent of at least one copolymer of a first monomer of an acrylic monomer or a methacrylic monomer, and a second monomer having at least one ethylene unsaturation and at least one polyoxyethylene chain. The emulsion or dispersion of the copolymer used in the method is also described.
