  • Patent number: 8967293
    Abstract: A method and a device to thermally fragment rock for excavation of vertical and directional boreholes in rock formations, preferentially hard rock, using highly exothermic reactions. Exothermic reactions are initiated directly in the pressurized, aqueous environment of a water-based drilling fluid preferably above the critical pressure of water (221 bar). After reaction onset temperatures within the reaction zone exceed the critical temperature for water (374° C.) providing supercritical conditions, which favor the stabilization of the reaction, e.g. a supercritical hydrothermal flame. Since reactions can be run directly in a water-based drilling fluid, the method proposed here allows high density drilling action as in conventional rotary drilling. A part from the hot reaction zone of the proposed reaction can be brought directly to the rock surface in case of hard polycrystalline rock, where high temperatures are required.

    Abstract: System and methods for creating shaped, non-circular boreholes in rocks especially for use with geothermal heat pump applications and for increasing wellbore support in applications such as horizontal oil and gas drilling are described. The systems and methods when applied to geothermal heat pumps create an elliptical shaped hole that is optimized for placing heat transfer tubes with a minimum of grout used. The significantly reduced cross-sectional area of the elliptical borehole also increases the overall drilling rate in rock and especially in hard rocks. In horizontal hard-rock drilling, creation of a horizontal non-circular borehole or modification of a circular borehole to a non-circular geometry is used to stabilize the borehole prior to casing insertion, and may also allow the use of lower mud pressures improving drilling rates. The system uses a non-contacting drilling system which in one embodiment uses a supersonic flame jet drilling system with a movable nozzle that swings between pivot points.

    Abstract: The invention relates to a procedure and device for the use of SC(supercritical)-GeoSteam for a possible complete exploitation of coal- and hydrocarbon deposits, preferably insitu, by means of “SC-GeoSteam Injection” well as the use of CO2 as the element for CO2 resource management within a closed system, with the necessary primary energy harvested in the form of SC-GeoSteam from a Supercritical Subsurface Boiler (SSB), also called a Geo heat exchanger, by means of super-deep drilled mine shafts. The SSB as the primary energy provider for SC-GeoSteam Injection can, at the same time, be used as a natural SCW* reactor. Because of the low viscosity of SC-GeoSteam and its high solubility in hydrocarbon, the hydrocarbons dissolve 100% in the supercritical fluid and are catalyzed in the presence of catalysts into high-grade hydrocarbons which can be separated via simple pressure reduction without complicated refining methods.

    Abstract: Utilisation of geothermal energy in depths above 5 km could contribute considerably to resolving the global problems related to a lack of energy and to glasshouse gases from fossil fuels. The invention describes innovative equipment which makes deep holes in geological formations (rock) by disintegrating the soil into blocks carried to the land surface through the excavated hole filled with liquid, using transport modules yielded up by gas buoyancy interaction in the transport module utilising supercavitation. In an opposite direction—by help of negative buoyancy—the necessary energy carriers, materials and components, or entire devices required for rock excavation, are carried to the bottom. The opportunity to transport rock in entire blocks reduces energy consumption considerably, because the rock is disintegrated in the section volumes only. Some of the extracted rock and material carried from the surface is used to make a casing of the hole using a part of the equipment.

  • Patent number: 7669937
    Abstract: A method for extracting minerals from a narrow-vein deposit by thermal fragmentation is provided. The method includes locating the vein and determining the extent thereof to form the boundaries of a stope. Access to the stope is prepared by forming a panel having an upper drift and a lower drift. Equipment for thermal fragmentation, including a burner, is installed from the upper drift. The burner moves along the panel surface in a sweeping motion, while rock chips spalled from the rock panel surface are collected. Multiple panels for processing can be realised, with lower panels being processed before upper panels, by excavating a sub-level to separate the lower and upper panels.

  • Publication number: 20100031653
    Abstract: Disclosed are a method and a device for utilizing supercritical subsurface steam as combined supercritical thermal and hydraulic power stations at an efficiency of 50 percent, using molten bath superdeep drilling technology, a hydrofrac process, and the special properties of the supercritical subsurface steam, such as the drastic increase in the thermal capacity, reduced viscosity, and inorganic solubility. The multifunctional use of said technologies and physical properties of supercritical subsurface steam in the inventive method allows a supercritical subsurface boiler to be tapped rapidly and at a low cost at a great depth while making it possible to produce electricity, power, process steam, and heat almost anywhere at one tenth of the cost of conventional fuel technologies and comparable expenses.

  • Publication number: 20100032207
    Abstract: System and methods for creating shaped, non-circular boreholes in rocks especially for use with geothermal heat pump applications and for increasing wellbore support in applications such as horizontal oil and gas drilling are described. The systems and methods when applied to geothermal heat pumps create an elliptical shaped hole that is optimized for placing heat transfer tubes with a minimum of grout used. The significantly reduced cross-sectional area of the elliptical borehole also increases the overall drilling rate in rock and especially in hard rocks. In horizontal hard-rock drilling, creation of a horizontal non-circular borehole or modification of a circular borehole to a non-circular geometry is used to stabilize the borehole prior to casing insertion, and may also allow the use of lower mud pressures improving drilling rates. The system uses a non-contacting drilling system which in one embodiment uses a supersonic flame jet drilling system with a movable nozzle that swings between pivot points.

    Abstract: A drill bit, system and method for penetrating a material such as a mineral bearing rock or the like is disclosed. The system comprises a drill bit comprising a cutting face comprising at least one cutting tool, an emitter of microwaves positioned behind the cutting face, wherein at least a portion of the microwaves are emitted in a direction away from the cutting face, and a reflector for directing the portion to the cutting face. In operation the emitted microwaves irradiate the material prior to the irradiated material being removed by the at least one cutting tool.

  • Publication number: 20090145659
    Abstract: In order to provide a method with apparatuses for safe final storage of highly radioactive waste products while safely coping with a reactor core melt, and final storage of the highly radioactive as well as slightly radioactive and medium-radioactive inventory when dismantling the nuclear power station itself in situ, it is proposed that a metal-shell drilled shaft composed of a casting be used as the final storage shaft at the nuclear power station location to which the material to be finally stored is supplied via a bomb-proof transport tunnel, which is hermetically isolated from the biosphere, from the reactor building or temporary stored by means of a magnetic sliding trans-port system for introduction to store, with filled final store sections migrating into the earth's mantel after separation from the remaining shaft, with residual heat being produced and under the influence of the force of gravity.
