| titleOfInvention | Method for the assisted recovery of hydrocarbons in fractured reservoirs |
| abstract | A method for recovering oil from a fractured reservoir having an oil-wettable matrix and comprising at least one injection well and one production well. This method comprises the following steps in such order: a)injecting by an injection well a solution of viscosity-enhancing surfactants, capable of penetrating into the array of fractures, having limited interaction with the matrix, and creating a plug in situ to reduce the perviousness of the fractures and to promote the passage of the solution of step b) into the matrix; b) injecting by an injection well a solution of surfactants, capable of interacting with the matrix to make water-wettable and to extract the oil therefrom; c) injecting by an injection well an aqueous solution to increasing the surface tension, impregnating the matrix and, after the plug in step a) is dissolved by the oil, driving the oil toward the production well. |
