Patent number: 8967293Abstract: 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.Type: GrantFiled: December 22, 2009Date of Patent: March 3, 2015Assignee: ETH ZurichInventors: Philipp Rudolf Von Rohr, Tobias Rothenfluh, Martin Schuler

Patent number: 4491367Abstract: Subterranean generation of heat as a source of energy optionally accompanied by the production of minerals. In subterranean formations of minerals that are capable of undergoing an enthalpic degradation, such degradation is artificially accelerated by several orders of magnitude. To this end a bore hole is drilled down to the desired formation and accelerated enthalpic degradation is made to occur by a suitable ignition. For the extraction of energy the bore hole is flushed with water and the resulting steam is withdrawn. In one embodiment, one and the same bore hole is used for charging water and withdrawing steam. In another embodiment the bore holes are arranged pairwise, one bore hole of each pair serving for ignition and introduction of water and the other serves for the withdrawal of steam.Type: GrantFiled: August 4, 1982Date of Patent: January 1, 1985Inventors: Miron Tuval, Emanuel Azmon, Avraham Melamed

Patent number: 4304308Abstract: A method and apparatus for making holes in coal seams in a coal mining system in which hot working gas is employed to impinge on the coal under high pressure and speed in order to disintegrate it and particularly for making inclined or horizontal holes which connect vertical drill holes which lead from the surface to the coal seam and through which the medium for gasifying the coal underground is blown in. The vertical drill holes which lead from the coal seam to the surface are used for blowing out gasification gases which are produced by the operation as well as for delivering the hot working gas. With the method of the invention, a gasification medium of high temperature and pressure is advantageously produced directly at the locations where the disintegrated coal is gasified, the disintegrated coal being formed by a rocket combustion process.Type: GrantFiled: September 19, 1980Date of Patent: December 8, 1981Assignee: Messerschmitt-Bolkow-Blohm GmbHInventors: German Munding, Helmut Hopmann, Armin Sowa, Christian Beckeryordersandforth, Walter Terschuren

Patent number: 4227582Abstract: A method and apparatus for perforating a well casing and surrounding formation are disclosed. The perforating apparatus includes a laser source for projecting a high intensity laser beam transversely through the well bore and surrounding formation and a nozzle assembly for injecting exothermically reactive gas along the path of the laser beam. The gas stream shields the output lens of the laser while accelerating the rate of laser beam penetration. The laser beam is actuated as the exothermic gas is discharged through the nozzle during a penetrating cycle, and the laser beam is interrupted while the exothermic gas is discharged during a melt ejection cycle following the penetrating cycle. When the laser tool is used for perforating materials such as concrete, stone and sand which do not react exothermically with the gas, a fluxing agent is discharged into the flow path of the nozzle and is entrained by the exothermically reactive gas during the penetrating cycle.Type: GrantFiled: October 12, 1979Date of Patent: October 14, 1980Inventor: Ernest H.

Patent number: 4168752Abstract: There is provided in accordance with the invention apparatus and a method for boring holes through carbonaceous deposits.The method involves the step of introducing combustion-supporting gases such as air under pressure through the apparatus installed in a well hole opposite the area to be bored. The apparatus comprises inner and outer flexible tubes with flexible, jointed armour and a directional nozzle which permits it to be bent and change attitude as necessary. The adjacent carbonaceous interface after being ignited is maintained in this condition by the combustion-supporting gas which is supplied under pressure. As the combustion proceeds, the pressure expels the combustion products and the gas injector is advanced along the channel it has previously formed.Type: GrantFiled: November 23, 1977Date of Patent: September 25, 1979Inventor: Karol Sabol

Patent number: 4036298Abstract: A method of mine-less connection of wells for underground gasification by the filtrational fire connecting technique is intended primarily for forming a single unitary gasification channel for underground gasification of coal, oil shale and oil-bearing beds. In the disclosed method of connecting wells or boreholes drilled for underground gasification, the coal bed is ignited in one of the wells situated in the direction of formation of the unitary gasification channel. After a center of combustion has been set in this well, an air blast is directed at a permanent flow rate into the well with which the connection is to be effected. The pressure of the air blast charged into the well is measured, and when the pressure drops considerably, an air blast is charged for connection purposes into the next successive well in the direction of formation of the gasification channel.Type: GrantFiled: August 12, 1975Date of Patent: July 19, 1977Inventors: Efim Vulfovich Kreinin, Kirill Nikolaevich Zvyagintsev

Patent number: 3990835Abstract: A technique is described for igniting the oil shale rubble pile in an in situ oil shale retort. A gas-air burner is lowered through a hole to a plenum over the oil shale to be ignited. An excess of air is passed through the hole and around the burner so that it is kept cool as the flame from it impinges on the rubble pile and the air also provides oxygen for combustion of carbonaceous material in the shale. Preferably the burner is in a cylindrical housing having a refractory exit nozzle at its lower end so that a hot flame is ejected downwardly. Air is brought to the inlet of the nozzle through an outer feed tube in the housing and coaxial therewith. Combustible gas is introduced through an inner axial feed tube which terminates short of the inlet end of the nozzle in a mixing chamber. A mixing orifice is provided between the mixing chamber and the nozzle for thorough mixing of the gas and inhibition of travel of the flame back into the burner.Type: GrantFiled: July 26, 1974Date of Patent: November 9, 1976Assignee: Occidental Petroleum CorporationInventor: Robert S.
