  • Patent number: 9163490
    Abstract: An in-situ oil shale production system used for economically mobilizing and extracting hydrocarbons in an underground oil shale deposit. The production system includes a plurality of injection wells, a plurality of production wells and a thermal energy carrier, called herein “TECF”. The TECF is injected through the injection wells into a naturally occurring, highly-permeable zone. The highly-permeable zone is used to create a porous heating element. The porous heating element, at high temperatures in the range of 900 to 1300 degrees F., mobilizes and retorts the hydrocarbons in the porous heating elements. The hydrocarbons with the TECF then flow from the porous heating element through the production wells to the ground surface for refining. The surface area of the large porous heating element provides a means for economic, in-situ retorting of hydrocarbons from a carbon-rich, oil shale geologic formation.

  • Patent number: 9085972
    Abstract: A system for producing hydrocarbons in situ from a heavy-oil and tar sand fixed bed, hydrocarbon deposit distributed substantially within a porous formation. The system includes at least one injection well and at least one production well drilled into the formation. A heated thermal-energy carrier fluid is circulated into the injection well and through a hydraulic fracture in the formation. The fracture is disposed between the injection well and the production well. The carrier fluid mobilizes hydrocarbons in situ by heating the hydraulic fracture and producing mobilized hydrocarbons through the production well. The hydrocarbons are then divided into at least two fluid fractures having differing chemical compositions.

  • Patent number: 8261823
    Abstract: A system and method for producing hydrocarbons in situ from an oil shale, fixed bed hydrocarbon formation disposed below a ground surface and having a naturally occurring, water-flow leached, higher permeability zone next to a lower permeability zone. The system includes at least one injection opening and at least one production opening in the naturally occurring, water-flow leached, higher permeability zone. A heated thermal-energy carrier fluid is injected into the injection opening and circulated horizontally through the higher permeability zone. The carrier fluid pyrolyzes the hydrocarbons in the lower and higher permeability zones in situ by heating the higher permeability zone and the adjacent lower permeability zone along an interface extending substantially between from the injection opening and the production opening and produces at least a portion of the mobilized hydrocarbons by flowing the carrier fluid with the pyrolyzed hydrocarbons through the production opening to the ground surface.

  • Patent number: 8091626
    Abstract: A downhole combustion unit for creating a high temperature, high pressure, thermal energy carrier fluid (TECF) inside a drill hole, which can be injected into a hydrocarbon, permeable zone for mining and producing hydrocarbons therefrom. The combustion unit includes an outer well-bore casing cemented in place in the drill hole. An inner well-bore casing, with injection holes in a lower portion thereof is used as a combustion chamber. The inner casing is suspended inside the outer casing. The configuration of the concentric outer and inner casings provide an outer annulus therebetween for receiving water from a ground surface and circulated downwardly under pressure. Compressed air and steam are circulated down the inside of the inner casing. A gas fuel tubing is disposed inside the inner casing for discharging the fuel into the combustion chamber.

  • Patent number: 7993110
    Abstract: A gas/air compressor system used for compressing a gas/air stream of air, oxygen, oxygen-enriched air and other combustible gases and delivering a moderate-to-high temperature, moderate-to-high pressure fluid to a pipeline connected to one or more injection wells. Fuel with cooling water is injected downhole for combustion in the compressed gas/air stream to be used for in-situ-retorting of oil shale, volatile coal beds, tar sands, heavy oil and other hydrocarbon or carbonaceous deposits. A preferred embodiment of the compressor system includes a compressor housing with a male screw rotor having helical lobes received in helical grooves in a female screw rotor. The housing includes a gas/air inlet for receiving the gas/air stream therein and a series of water/mineral injectors for injecting a water/mineral slurry into the rotating screw rotors. The water/mineral slurry acts as a sealant, a lubricant and also a coolant for male and female screw rotors during the compression cycle.

  • Patent number: 7647969
    Abstract: A method for growth of a hydraulic fracture or a tall frac is described wherein the tall frac is disposed next to a well bore using a sandpacked annulus. Also, a method for creating a permeable well bore annulus is disclosed. The method for creating the tall frac includes creating a linear-sourced, cylindrical stress field by maneuvering the intersection of two independent friction-controlled pressure gradients of a frac pad fluid. The intersection of these two frac pad fluid pressure gradients can be controlled when the frac pad fluid traverses along a well bore sandpacked annulus. The first pressure gradient is created by controlling the fluid flow rate and the consequent, friction pressure loss in the frac pad fluid flow through a portion of the sandpacked annulus, located above the top of the upwardly propagating tall frac hydraulic fracture. The first pressure gradient must be significantly greater than the average gradient of the formation, frac-extension pressure gradient.

  • Publication number: 20070240906
    Abstract: A tapered reamer bit which achieves a reaming function at least in part by tension fracturing a geographic formation such that the resulting fragments of the formation are forced upward and/or backward and without relying on multiple rotatably positionable cylinders disposed on the reamer bit. Because of the tooth placement of the tapered reamer bit, a rotational force applied thereto results in a downward/forward force while reaming out a hole through a geographic formation.
