titleOfInvention | METHOD OF MODIFYING WATER PERMEABILITY OF UNDERGROUND FORMATION |
abstract | The invention relates to a method for modifying the water permeability of an oil-containing underground formation, said method comprising at least the following steps: obtaining an injected fluid from a dispersion of a hydrophilic phase in a lipophilic phase using water or saline, wherein the dispersion contains a hydrophilic phase containing at least one linear (co)polymer E, a lipophilic phase, at least one interfacial polymer consisting of at least one monomer of formula (I) E that when released and in contact with water, the viscosity of the injected fluid becomes greater than the viscosity of the oil in the reservoir. |
