Patent number: 6476169Abstract: Improved methods of treating water and hydrocarbon producing subterranean formations to reduce the water permeability thereof are provided. The methods basically comprise introducing into the formation a water flow resisting chemical which attaches to adsorption sites on surfaces within the porosity of the formation and reduces the water permeability thereof without substantially reducing the hydrocarbon permeability thereof. The water flow resisting chemical is comprised of a polymer of at least one hydrophilic monomer and at least one hydrophobically modified hydrophilic monomer.Type: GrantFiled: September 28, 2000Date of Patent: November 5, 2002Assignee: Halliburton Energy Services, Inc.Inventors: Larry S. Eoff, B. Raghava Reddy, Eldon D. Dalrymple

Publication number: 20020137858Abstract: A high molecular weight water soluble acrylamide based polymer having improved flocculating and dewatering properties is provided. The polymer is prepared by a process in which a small quantity of a chain branching agent is added to the polymerization reaction mixture continuously or stepwise while the monomers are polymerized. The polymer is useful in solid/liquid separations such as flocculants and coagulants in wastewater treatment applications, and as thickening agents.Type: ApplicationFiled: March 13, 2002Publication date: September 26, 2002Applicant: Ecole POlytechnique Federale De Lausanne (EPFL)Inventors: Jose Hernandez-Barajas, Christine Wandrey, David Hunkeler

Patent number: 6423799Abstract: Disclosed is an extremely rapidly photo-addressable storage media from inherently slow photo-addressable polymers by irradiating a substrate over a large area with a light source suitable for conventional inscription so that an optical anisotropy, i.e. a double refraction with a preferential direction in the plane of the substrate occurs. If the substrates so prepared are briefly intensively irradiated, the pattern is inscribed extremely rapidly and permanently. The invention also relates to novel side-chain polymers in which high optical anisotropy can be generated by irradiation. This optical anisotropy is very heat stable.Type: GrantFiled: November 17, 1998Date of Patent: July 23, 2002Assignee: Bayer AGInventors: Horst Berneth, Uwe Claussen, Serguei Kostromine, Ralf Neigl, Hans-Joachim Vedder

Patent number: 6238486Abstract: The invention provides novel cationic flocculant dispersion polymers that can be utilized in the methods disclosed herein. This invention also provides methods for detecting cationic flocculants wherein said flocculants may be made via a dispersion process, a latex process or a dry polymer process. The flocculants are used to flocculate solids from liquid components of an industrial food process. The detection method involves the use of monoclonal antibodies to determine the presence or concentration of the cationic flocculants in the liquids.Type: GrantFiled: March 10, 1999Date of Patent: May 29, 2001Assignee: Nalco Chemical CompanyInventors: Andrew J. Dunham, Cathy C. Johnson, Kristine S. Salmen, John W. Sparapany, Anthony G. Sommese
