Boring Or Penetrating The Earth > Processes > Boring With Specific Fluid > Boring By Fluid Erosion Boring By Fluid ErosionBoring By Fluid Erosion patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.01/03/08 - 20080000694 - Mechanical and fluid jet drilling method and apparatus A device useful for conducting lateral or transverse excavating operations within a wellbore comprising a rotating drill bit with jet nozzles on a flexible arm. The arm can retract within the housing of the device during deployment within the wellbore, and can be extended from within the housing in order ... 07/05/07 - 20070151766 - Mechanical and fluid jet horizontal drilling method and apparatus A device useful for conducting lateral or transverse excavating operations within a wellbore comprising a rotating drill bit with jet nozzles on a flexible arm. The arm can retract within the housing of the device during deployment within the wellbore, and can be extended from within the housing in order ... 06/14/07 - 20070131455 - Nozzle unit and method for excavating a hole in an object A nozzle unit for generating an abrasive jet. The nozzle unit has a first nozzle connected to a pressurized carrier fluid supply; a mixing chamber in which the first nozzle discharges; and a second nozzle connected to the mixing chamber. An abrasive particle inlet discharges in the mixing chamber. A ... 07/27/06 - 20060162964 - Tool for excavating an object A tool for excavating an object, the tool comprising a jetting system having nozzle means arranged to receive a fluid and abrasive particles via an abrasive particle inlet, and arranged to impinge the object to be excavated with a jetted stream of the fluid mixed with the abrasive particles, the ... 06/15/06 - 20060124362 - Floating head reaction turbine rotor with improved jet quality A rotary jetting tool including a pressure-balanced rotor, which is achieved using a vented volume. Axial movement of the rotor relative to the housing caused by pressure imbalances acting on the rotor selectively uncovers or opens a vent that places the volume in fluid communication with an ambient volume, enabling ... 06/01/06 - 20060113114 - Drilling tool and method A drill tool comprising a drill pipe having a turbine and a hydraulic pump, wherein drilling fluid is passed through the turbine and into the hydraulic pump through a hollow shaft in the drill pipe. The drill tool also includes a high pressure jet at a distal end of the ... 02/02/06 - 20060021798 - Impact excavation system and method with particle separation A system and method for excavating a subterranean formation, according to which a suspension of liquid and a plurality of impactors are introduced into at least one cavity formed in a body member and are discharging from the cavity so that the impactors remove a portion of the formation. The ... 01/26/06 - 20060016624 - Impact excavation system and method with suspension flow control A system and method for excavating a subterranean formation, according to which a suspension of liquid and a plurality of impactors are passed between a drill string to a body member for discharge from the body member to remove at least a portion of the formation. The flow of the ... 01/19/06 - 20060011386 - Impact excavation system and method with improved nozzle A system and method for excavating a subterranean formation, according to which a suspension of liquid and a plurality of impactors is introduced into at least one cavity formed in the body member. The suspension is discharged from a nozzle disposed in the cavity towards the formation so that the ... 10/27/05 - 20050236188 - Systems and methods for remotely determining and changing cutting modes during decoking A decoking system that not only enables an operator to remotely switch the coke-cutting process from boring to cutting mode without removing the drill stem from the coke drum, but also to remotely determine the drill stem's mode so that efficiency, safety and convenience are not compromised, is provided. ... 10/20/05 - 20050230152 - Suspended abrasive waterjet hole drilling system and method A suspended abrasive waterjet narrow kerf cutting method is reconfigured to simultaneously drill multiple, closely-spaced holes in a target, including holes in confined non line-of-sight locations. Working fluid nozzles can be located on a flat or non-flat tool surface and arranged in uniform or non-uniform patterns, in an angled or ... 06/23/05 - 20050133270 - Oil recovery using non-cryogenically produced nitrogen and off-gas recycling An enhanced oil recovery process includes non-cryogenically generating a relatively inert gas, such as nitrogen, or nitrogen-enriched air, near the site of an oil-bearing formation. The relatively inert gas is injected into the formation, so as to displace oil from the formation. One or more off-gases, also obtained from the ... ### FreshPatents.com Support |
