  • Patent number: 8273693
    Abstract: Coacervate gels having excellent shear viscosities and other properties are made with anionic or cationic polymers, a smaller amount of a surfactant having a charge opposite that of the polymer, and a hydrophobic alcohol and an effective amount of a phosphorus-containing compound sufficient to increase the viscosity of coacervate gels up to 3 times as compared to the gels in the absence of the phosphorus-containing compound. The Zeta Potential of the gel is maintained at an absolute value of at least 20. Optional gel promoting additives include betaines and amine oxides. A preferred gel comprises poly diallyl dimethyl ammonium chloride, a lesser amount of sodium lauryl sulfonate, and lauryl alcohol. The gels are particularly useful in well drilling fluids and well fracturing fluids.

  • Publication number: 20120088700
    Abstract: 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.

  • Publication number: 20110303415
    Abstract: 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.
