Method of inhibiting penetration of water into the well for the extraction of hydrocarbon fluid medium from an underground reservoir |
| abstract |
The invention relates to a method of inhibiting the penetration of water into a well for the extraction of hydrocarbon fluid from a subterranean formation, comprising: a) introducing into said formation at least one composition for treating the near-stem zone containing at least one emulsion or one dispersion in an organic solvent at least one copolymer: a first monomer selected from an acrylic monomer or a methacrylic monomer, and a second monomer containing at least one ethylenic unsaturation and at least At least one polyoxyethylene chain. The present invention also relates to emulsions and dispersions of copolymers suitable for use in the above method. |
