Publication number: 20120088700Abstract: An asphaltene and resin precipitation inhibiting solution formed of an asphaltene and resin precipitation inhibiting compound and a solvent miscible in a carbon dioxide liquid or supercritical fluid. The inhibiting compound includes a head region with an affinity for asphaltene and resin components of a hydrocarbon mixture that is greater than its affinity for water, carbon dioxide, and aliphatic components of the hydrocarbon mixture. The head region includes one or more unsaturated hydrocarbon groups or one or more nonionic dipolar groups. The inhibiting compound also includes a tail region with an affinity for carbon dioxide that is greater than its affinity for substantially all components of the hydrocarbon mixture and water. The tail region includes one or more nonionic quadrupolar groups. An effective amount of solution is added to a hydrocarbon mixture in an underground reservoir when employing a carbon dioxide fluid to flush the hydrocarbon mixture from the reservoir.Type: ApplicationFiled: October 12, 2011Publication date: April 12, 2012Applicant: CHAMPION TECHNOLOGIES, INC.Inventor: Paul R. Hart

Publication number: 20110303415Abstract: This invention relates to an aqueous-swellable and degradable diverting system and the use of the system in treating a subterranean formation penetrated by a wellbore. The diverting system comprises a carrier fluid and a partially dehydrated or anhydrous borate source material that does not swell or does not swell substantially when placed in contact with the carrier fluid. The carrier fluid is capable of carrying and placing the borate source material into a stimulation network substantially distanced from a wellbore. The carrier fluid may be a non-aqueous fluid, or when the average size of the borate source material is sufficient large, the carrier fluid may also be an aqueous fluid. Exposure of the diverting composition to sufficient amount of aqueous fluid swells the borate source material, bridges a desired portion of the stimulation network and then dissolves at least a portion of the diverting composition.Type: ApplicationFiled: June 11, 2010Publication date: December 15, 2011Inventors: Bradley L.
