Method of inhibiting water penetration into extraction wells of hydrocarbon fluids from subterranean reservoirs |
| abstract |
The present invention relates to a method of inhibiting the penetration of water into an extraction well of hydrocarbon fluids from a subterranean reservoir, the method comprising: a) injecting into said reservoir at least one treatment fluid, said treatment fluid comprising at least one At least one emulsion or a dispersion of a copolymer in an organic solvent, the copolymer derived from: - a first monomer selected from acrylic monomers or methacrylic monomers, and - comprising at least one ethylene Unsaturation and second monomer of at least one polyoxyethylene chain. The present invention also relates to emulsions and dispersions of copolymers useful in the above-described methods. |
