Patent number: 9249351Abstract: Viscoelastic surfactant based aqueous fluid systems useful as thickening agents in various applications, e.g. to suspend particles produced during the excavation of geologic formations. The surfactants are zwitterionic/amphoteric surfactants such as dihydroxyl alkyl glycinate, alkyl ampho acetate or propionate, alkyl betaine, alkyl amidopropyl betaine and alkylimino mono- or di-propionates derived from certain waxes, fats and oils. The thickening agent is used in conjunction with an inorganic water-soluble salt or organic additive such as phthalic acid, salicylic acid or their salts.Type: GrantFiled: December 22, 2010Date of Patent: February 2, 2016Assignee: Rhodia OperationsInventors: Manilal S. Dahayanake, Jiang Yang, Joseph H. Y. Niu, Paul-Joel Derian, Ruoxin Li, David Dino

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.

Publication number: 20040249062Abstract: Aqueous emulsions of oils, gums or preferably masked (poly)isocyanate resins are prepared by kneading a mixture containing (1) a preferably masked (poly)isocyanate phase (A) with a viscosity of at least 3 Pa.s or a consistency of at least 200, and (2) an aqueous phase including water, at least one surfactant (B) and optionally at least one water-soluble thickening polymer (C). The relative amounts of water (B) and optionally (C) being such that the aqueous phase has a viscosity or consistency preferably no lower than that of the preferably masked (poly)isocyanate phase (A). The kneading is performed for a sufficient time and with sufficient shear to give an oil-in-water emulsion with a particle size of 0.1-5 &mgr;m, and optionally diluting the medium with water.Type: ApplicationFiled: April 15, 2004Publication date: December 9, 2004Applicant: RHONE-POULENC CHIMIEInventors: Paul-Joel Derian, Bruno Langlois, Alain Senechal
