    Abstract: The present invention relates to a method for recovering methane gas from natural gas hydrates. In particular, it includes the step of adding a gas mixture containing air and carbon dioxide to an NGH of deep sea and the step of replacing the methane gas with gas mixture and the step of decomposition-replacement of methane hydrate. In accordance with the present invention, the invention is possible use as a technique for recovery of methane gas in the all-weather to induce replacement reaction using a gas mixture when the temperature of the technology applied is low and to induce degradation of solid methane hydrate by mixing gas when the temperature of the region technique is applied is high. Further, the method makes it possible to reduce costs than using conventional methods because the air is collected directly from the NGH reservoirs and compressed and is injected as a mixture with carbon dioxide and, there is no need to transport the infusion another gas.

  • Publication number: 20140096971
    Abstract: A method of rapidly and essentially simultaneously creating and feeding a dispersion into a hydrocarbon process stream. This method allows for the effective use of chemical additives in a hydrocarbon process line that are highly unstable or that are very difficult to disperse. This is especially helpful in hydrofracturing operations as the very rapid flow rates require very fast dispersion formations. As a result the method allows greater fracking pressures which can be obtained with lower energy inputs and by using lessor amounts of chemical additives. As a result hydrocarbon extraction can be accomplished in a manner which is both more environmentally friendly as well as less expensive.

  • Patent number: 8616284
    Abstract: Viscoelastic surfactant (VES) gelled aqueous fluids containing water, a VES in an amount effective to increase the viscosity of the water, and an internal breaker may be useful in removing a residual polymer from a hydraulic fracture. Optionally, a pseudo-crosslinker may be present to further improve the properties related to treatment fluid placement and polymer clean-up. A plurality of aliquots of VES gelled fluid may be injected into a subterranean formation. A stop-start interval may exist between the injection of each aliquot. The VES gelled fluid may contact at least some of the residual polymer in the hydraulic fracture, and a broken fluid is formed once the viscosity of the VES gelled fluid is reduced with the internal breaker. At least a portion of the residual polymer and a majority of the broken fluid may be removed.

  • Publication number: 20130341031
    Abstract: Insensitive explosive compositions were prepared by reacting di-isocyanate and/or poly-isocyanate monomers with an explosive diamine monomer. Prior to a final cure, the compositions are extrudable. The di-isocyanate monomers tend to produce tough, rubbery materials while polyfunctional monomers (i.e. having more than two isocyanate groups) tend to form rigid products. The extrudable form of the composition may be used in a variety of applications including rock fracturing.

  • Patent number: 8602098
    Abstract: The present invention relates generally to in situ hydrate control during hydrocarbon production when applying a recovery method utilizing cyclic injection of light hydrocarbon solvents. Hydrate formation is limited by creating an energy reserve within a hydrocarbon reservoir adjacent to the wellbore. A heated solvent is injected during an injection phase of a cyclic solvent dominated recovery process to form a heated region adjacent to the wellbore at the end of an injection cycle. The energy reserve is used to act against the evaporative cooling effect caused by subsequent production and associated depressurization to maintain reservoir conditions outside of hydrate formation conditions. In situ conditions are estimated and injected energy amounts are controlled.

  • Patent number: 8573303
    Abstract: A method and apparatus for hydrocarbon recovery and/or treatment of frac water includes introducing a volume of water into a formation, recovering the introduced water, with the recovered introduced water further comprising suspended hydrocarbon product. The recovered liquid is treated to remove substantial amounts of the suspended hydrocarbon product, provide the treated recovered liquid with a ORP in a range of 150 mv to 1000 mv, and partially desalinated, and is either re-introduced as treated recovered liquid with the ORP into a formation to assist in recovery of additional hydrocarbon deposits in the formation, or is stored to reduce the ORP and then subsequently discharged into surface waters.

  • Patent number: 8567502
    Abstract: Nanoparticle-treated substrates, such as screens, sand beds or proppant beds, may effectively filter and purify fluids such as waste water or fluids produced from a formation, as well as other liquids. When tiny contaminant particles in a fluid such as waste water flow contact the nanoparticle-treated substrate, the nanoparticles will capture and hold the tiny contaminant particles on the substrate due to the nanoparticles' surface forces, including, but not necessarily limited to van der Waals and electrostatic forces or other associative forces. Coating agents such as alcohols, glycols, polyols, vegetable oil, and mineral oils may help apply the nanoparticles to the surfaces of structures in the filter beds or packs.

  • Patent number: 8534359
    Abstract: Oil sands and like host materials are leached with a selected leachant to render pumpable the oil (including heavy oil, bitumen or kerogen and asphaltenes) as leachate. In a preferred embodiment, natural deposits are in situ leached and the leachate recovered and removed for treatment. The leachant is separated and recycled. The leachant is selected to be biodegradable and to not precipate asphaltenes, and to comprise monoterpenes of the formula C10H16. The overall process allows environmentally acceptable resource development and contaminated site remediation.
