  • Publication number: 20150027694
    Abstract: Embodiments of the present invention relate to heater patterns and related methods of producing hydrocarbon fluids from a subsurface hydrocarbon-containing formation (for example, an oil shale formation) where a heater cell may be divided into nested inner and outer zones. Production wells may be located within one or both zones. In the smaller inner zone, heaters may be arranged at a relatively high spatial density while in the larger surrounding outer zone, a heater spatial density may be significantly lower. Due to the higher heater density, a rate of temperature increase in the smaller inner zone of the subsurface exceeds that of the larger outer zone, and a rate of hydrocarbon fluid production ramps up faster in the inner zone than in the outer zone. In some embodiments, a ratio between a half-maximum sustained production time and a half-maximum rise time of a hydrocarbon fluid production function is relatively large.

  • Publication number: 20110259590
    Abstract: A sub-surface hydrocarbon production system comprising an energy delivery well extending from the surface to a location proximate a bottom of the hydrocarbons to be produced. A production well extends from the surface to a location proximate the hydrocarbon and a convection passage extends between the energy delivery well and the production well thereby forming a convection loop. The energy delivery well and the production well intersect at a location proximate the hydrocarbon such that the convection loop is in the form of a triangle. Preferably, the convection passage extends upwardly from a point at which the convection passage intersects the production well. The system also includes a heater, such as an electric heater or down-hole burner, disposed in the energy delivery well.

  • Patent number: 8016589
    Abstract: Included is a method of starting up a direct heating device having a fuel introduction zone, a combustion zone and a process zone that is in heat exchange relationship with said combustion zone. Prior to the introduction of a fuel fluid into said combustion zone, an oxidant fluid, having a high temperature, is passed through the combustion zone for a warm-up time period sufficient to raise the temperature of the direct heating device to a desired temperature. Steam or a process fluid is passed through the process zone followed by the introduction of a fuel fluid into the fuel introduction zone. After the device has been heated up a process fluid is introduced through the process zone. Thereafter, the introduction of steam through the process zone may be stopped.

  • Patent number: 7927507
    Abstract: Compositions for hydrogen storage and methods of making such compositions employ an alloy that exhibits reversible formation/deformation of BH4? anions. The composition includes a ternary alloy including magnesium, boron and a metal and a metal hydride. The ternary alloy and the metal hydride are present in an amount sufficient to render the composition capable of hydrogen storage. The molar ratio of the metal to magnesium and boron in the alloy is such that the alloy exhibits reversible formation/deformation of BH4? anions. The hydrogen storage composition is prepared by combining magnesium, boron and a metal to prepare a ternary alloy and combining the ternary alloy with a metal hydride to form the hydrogen storage composition.

  • Patent number: 7874350
    Abstract: An apparatus for generating a heated product stream downhole is provided wherein a fuel rich mixture is reacted downhole by contact with a catalyst to produce a partially reacted product stream, the fuel rich mixture comprising fuel and oxygen. The partially reacted product stream is brought into contact with an oxidant thereby igniting combustion upon contact producing a combustion product stream. The combustion product stream may be cooled by injecting a diluent flow such as water or CO2. The cooled combustion product stream may be injected into oil bearing strata in order to reduce the energy requirements for the production of heavy oil.

  • Patent number: 7770646
    Abstract: A downhole burner for a steam generator includes an injector and a cooling liner. Steam enters the burner through holes in the cooling liner. Combustion occurring within the cooling liner heats the steam and increases its quality and may superheat it. The heated, high-quality steam and combustion products exit the burner and enter an oil-bearing formation to upgrade and improve the mobility of heavy crude oils held in the formation. The injector includes a face plate, a cover plate, an oxidizer distribution manifold plate, and a fuel distribution manifold plate. The cooling liner has an effusion cooling section and effusion cooling and jet mixing section. The effusion cooling section includes effusion holes for injecting steam along the cooling liner surface to protect the liner. The effusion cooling and jet mixing section has both effusion holes and mixing holes for injecting steam further toward central portions of the burner.

  • Patent number: 7743826
    Abstract: A system and process is disclosed for retorting oil shale and extracting shale oil and other hydrocarbons therefrom, in which a cased heat delivery well is drilled generally vertically through an overburden and then through a body of oil shale to be retorted to the bottom thereof, generally horizontally under the body of oil shale to be retorted, and then back to the earth surface. Heat energy is transmitted conductively to the body of oil shale to be retorted from a closed loop heat delivery module in the well, the module comprising a fluid transmission pipe containing a heating fluid heated to at least a retorting temperature. Heat energy is also transmitted to the body of oil shale to be retorted above the fluid transmission pipe by vapor conduits that conduct retort vapors upward through the body of oil shale to be retorted; the ascending retort vapors condense and reflux, delivering their latent heat of vaporization to the body of oil shale to be retorted, and the condensed retort liquids descend.
