Patent number: 4778607Abstract: A water-soluble inorganic non-crosslinking salt is incorporated in an aqueous gel-like solution of a water-soluble uncrosslinked polymer at an initial higher polymer concentration. The salt accelerates the dilution of the polymer solution with an aqueous diluent to an aqueous polymer solution at a predetermined lower polymer concentration. The gel-like polymer solution is diluted without substantially degrading the polymer so that it retains desirable properties for use in a hydrocarbon recovery process.Type: GrantFiled: March 17, 1987Date of Patent: October 18, 1988Assignee: Marathon Oil CompanyInventors: Perry A. Argabright, Wayne E. Luetzelschwab

Patent number: 4744419Abstract: Conformance improvement is achieved in a subterranean hydrocarbon-bearing formation using a gel comprising a high molecular weight, water-soluble, carboxylate-containing polymer, a chromium III/carboxylate complex capable of crosslinking the polymer and an aqueous solvent. The gel components are combined at the surface and injected into the desired treatment zone via a wellbore to form a continuous single-phase gel.Type: GrantFiled: December 9, 1986Date of Patent: May 17, 1988Assignee: Marathon Oil CompanyInventors: Robert D. Sydansk, Perry A. Argabright

Patent number: 4687586Abstract: An on-site, in-line process and system for recovering oil from oil-bearing subterranean formations which involves the production, modification, dilution and injection of a polymer solution, preferably consisting essentially of an aqueous solution of a partially hydrolyzed polyacrylamide, having injectivity and mobility properties capable of meeting the specific permeability requirements of substantially any subterranean formation to be achieved. The polymer solutions prepared by the process and system can be used as drive fluids for displacing oil (secondary polymer flood) in an oil-bearing formation, as mobility buffers to follow micellar dispersion floods in the conjoint presence of chemical reagents in other chemical floods (e.g., surfactant, caustic, etc.), or they can follow a water flood. The solutions can also be used to promote pipelining of high viscosity crude oil.Type: GrantFiled: December 5, 1985Date of Patent: August 18, 1987Assignee: Marathon Oil CompanyInventors: Perry A. Argabright, John S. Rhudy

Patent number: 4683949Abstract: Conformance improvement is achieved in a subterranean hydrocarbon-bearing formation using a gel comprised of a high molecular weight water-soluble acrylamide polymer, a chromium III/carboxylate complex capable of crosslinking the polymer and an aqueous solvent. The gel components are combined at the surface and injected into the desired treatment zone via a wellbore to form a continuous single-phase gel. The gel is tailored to a specific subterranean application by first determining the treatment demands of the desired subterranean zone, then predetermining the gelation rate and resultant gel strength and stability which are required of a gel to meet the demands, and finally producing the gel having the required predetermined properties under controlled surface conditions by utilizing observed correlations between specific controllable gelation parameters and resultant gel properties.Type: GrantFiled: January 27, 1986Date of Patent: August 4, 1987Assignee: Marathon Oil CompanyInventors: Robert D. Sydansk, Perry A. Argabright

Patent number: 4397748Abstract: A method of reducing the fluid flow friction loss of fluid waste materials in the conduits of sanitary sewer systems while at the same time maintaining the solid materials in the fluid in a flowable condition by introducing into a sewer system about 1 to about 10,000 ppm of an aqueous solution of a partially hydrolyzed polyacrylamide polymer having a preselected average molecular weight and molecular weight distribution.Type: GrantFiled: November 12, 1981Date of Patent: August 9, 1983Assignee: Marathon Oil CompanyInventors: Perry A.

Patent number: 4383930Abstract: Polymer mobility control agents useful in supplemental oil recovery processes, which give improved reciprocal relative mobilities, are prepared by initiating the polymerization of a monomer containing a vinyl group with a catalyst comprising a persulfate and ferrous ammonium sulfate. The vinyl monomer is an acrylyl, a vinyl cyanide, a styryl and water soluble salts thereof.Type: GrantFiled: June 20, 1980Date of Patent: May 17, 1983Assignee: Marathon Oil CompanyInventors: Perry A.

Patent number: 4098337Abstract: Improved injectivity profiles and/or vertical conformance in flooding heterogeneous formations containing high permeability zones is obtained by injecting an aqueous polyacrylamide solution and an aqueous formaldehyde solution into the formation and allowing the polyacrylamide to react with the formaldehyde in the relatively high permeability zones to form a gel. Thereafter, improved sweep efficiency is realized in displacing hydrocarbon from the lesser permeability zones.Type: GrantFiled: July 1, 1977Date of Patent: July 4, 1978Assignee: Marathon Oil CompanyInventors: Perry A.
