Patent number: 7789144Abstract: There is a method for enhancing the recovery of oil from a reservoir. The method has the step of a) introducing a flooding fluid into the reservoir and b) extracting the oil through a wellbore at a location different than the point of introduction of the flooding fluid into the reservoir. The flooding fluid has water and an amount of one or more non-polymeric viscoelastic surfactants sufficient to provide an interfacial surface tension of about 1 mNm or less and a viscosity of about 10 cps or more. The one or more surfactants is selected from the group of one or more cationic surfactants, one or more zwitterionic surfactants, one or more amphoteric surfactants, one or more anionic surfactants, and combinations thereof.Type: GrantFiled: October 30, 2008Date of Patent: September 7, 2010Assignee: Rhodia, Inc.Inventors: Manilal S. Dahanayake, Bruno Langlois, Paul-Joel Derian, Jean-Pierre Marchand

Patent number: 7375165Abstract: The invention relates to thermoplastic compositions comprising a thermoplastic polyamide matrix and at least one additive which modifies the interaction between the matrix and an agent. The purpose of the invention is to provide an additive which modifies the interaction between a copolyamide-type thermoplastic copolyamide matrix and at least one agent. The aforementioned additive, which comprises at least one hyperbranched functionalised polymer, is not compatible with the matrix. Moreover, said additive can be used for the controlled modification of the interaction between the thermoplastic copolyamide and an internal or external chemical agent. Preferably, the composition does not contain hyperbranched polymers which produce therein a reduction in the molar mass of matrix M which is greater than or equal to 7% in relation to a sample composition which comprises matrix M but does not contain hyperbranched polymer additive(s). Said mass measurement is taken preferably using a determined protocol P.Type: GrantFiled: December 16, 2002Date of Patent: May 20, 2008Assignee: RhodianylInventors: Jean-François Sassi, Franck Touraud, Natalia Scherbakoff, Christine Vidil, Christophe Paulo, Sandrine Rochat, Jean-Pierre Marchand, Bertrand Bordes
