Patent number: 9010423Abstract: 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.Type: GrantFiled: July 26, 2010Date of Patent: April 21, 2015Assignee: Rhodia OperationsInventors: Max Chabert, Mikel Morvan

Patent number: 8851187Abstract: A method for enhancing recovery of oil from an oil-bearing carbonate formation within a reservoir. The method has the steps of (a) introducing a viscous gel under pressure into the oil-bearing carbonate formation and (b) extracting oil. The aqueous viscous gel has water and an amount of a non-polymeric viscosifying surfactant sufficient to provide the flooding fluid with an oil/water interfacial surface tension of about 10 mN/m or less and a viscosity of about 10 cP or more of the one or more non-polymeric surfactants. The one or more non-polymeric, viscosifying surfactants is selected from the group of one or more cationic surfactants, one or more zwitterionic surfactants, one or more anionic surfactants, one or more amphoteric surfactants, and combinations thereof. In a preferred embodiment, the aqueous viscous gel is also substantially free of solids.Type: GrantFiled: December 20, 2011Date of Patent: October 7, 2014Assignee: Rhodia, Inc.Inventors: Manilal Dahanayake, Max Chabert, Mikel Morvan, David Sorin
