20100252333 | SYSTEM FOR DRILLING A WELLBORE - A system is disclosed for drilling a wellbore ( | 10-07-2010 |
20110011648 | TOOL FOR CUTTING COKE AND OTHER HARD MATERIALS IN DRUMS - A tool used for cutting coke or other hard materials in drums, adapted for being mounted to a boring rod with which the water can be run under pressure into the tool thus that, the water can be run toward the boring and cutting nozzles, being provided with a valve mechanism that can rotate about a coupling angle for releasing and closing the flow channel ports depending on a control input, with a first coupling position of the valve mechanism for boring and another coupling position for cutting, whereby the valve mechanism can be coupled at a water pressure reduced to the coupling pressure by rotating about the coupling angle, is simplified as to construction and handling in that the valve mechanism comprises a valve body in the water intake area of the casing, which has a cylindrical shape and a section for the water flowing inside the casing, as well as being rotationally mounted and having the possibility to be lifted and lowered in a cylindrical section of the inner wall of the casing, the valve body being displaceable at working pressure to a lower position against a spring tension—depending on the preset control for the individual desired function of the tool—and on occurring the coupling pressure, under spring tension, to an upper position relative to a rotating motion of the valve body about the coupling angle. | 01-20-2011 |
20120012400 | HEAD FOR INJECTING CONSOLIDATING PRESSURISED FLUID MIXTURES INTO THE GROUND - A head includes an outer cylindrical body with at least one upper inlet for fluids, at least one outlet side nozzle and at least one helical duct having a helical central line. The duct connects the upper inlet to the nozzle and imparts the fluid flowing through it a helical motion about the longitudinal axis of the outer body towards the nozzle. The helical duct is progressively tapered towards the nozzle and includes a terminal length of the duct which is radiused to the nozzle in a tapered manner, both when viewed in cross-sectional planes parallel to the longitudinal axis and tangent to the helical central line, as well as when viewed in cross-sectional planes perpendicular to the longitudinal axis. | 01-19-2012 |
20120181089 | Method and Means for Drilling an Earthen Hole - An earthen hole drilling device having an elongated tube with first and second ends where a source of vacuum pressure is connected to the first end and shroud is connected to the second end. A waterline is connected to a source of pressurized water at one end and extends into an interior of the shroud through an opening where the line is connected to a nozzle that is angled at 45°. The shroud additionally has at least one opening that allows air induction/conduction through the shroud in order to dislodge material that accumulates within the shroud. | 07-19-2012 |
20120255791 | METHOD OF DRILLING AND ABRASIVE JET DRILLING ASSEMBLY - A method of drilling comprises providing a drill string in a borehole, the drill siring comprising an abrasive jet drill head including a jet nozzle, and providing a fluid passageway between the object's surface and the jet nozzle; supplying a fluid mixture comprising magnetic particles to the abrasive jet drill head and blasting from the nozzle an abrasive jet into impingement with the object; and modulating a jetting concentration of magnetic particles in the abrasive jet by modulating a magnetic field a first value, at which magnetic particles are collected from the fluid mixture, and a second value, at which magnetic particles are released into the fluid mixture. Further, an abrasive jet drilling assembly comprising a modulation means for modulating the concentration of the magnetic abrasive particles in the fluid jet a modulation control means for selectively changing a magnetic field between first and second values. | 10-11-2012 |
20120255792 | METHOD OF DRILLING AND JET DRILLING SYSTEM - A method of drilling comprises providing a drill string in a borehole, the drill string comprising an abrasive jet drill head including a jet nozzle and providing a passageway for fluid to the nozzle; supplying a supply fluid comprising a supply concentration of abrasive particles to the jet drill head; generating an jet comprising a jetting concentration of abrasive particles at the nozzle, wherein the jetting concentration depends on the supply concentration; and modulating the jetting concentration; wherein the supply concentration is modulated in order to modulate the jetting concentration. Further, an drilling assembly comprising an drill head with a jet nozzle, a passageway for fluid from a drill string to the jet nozzle, and a modulation means arranged along the fluid passageway for modulating the concentration of abrasive particles in fluid flowing through the fluid passageway towards the jet nozzle. | 10-11-2012 |

20160108683 | MUD MOTOR WITH INTEGRATED ABRASION-RESISTANT STRUCTURE - A housing for a mud motor is disclosed. The housing comprises a female member comprising a female mating section and a male member comprising a male mating section and a housing section. The male mating section is matingly received within the female mating section. The collar is positioned on the housing section. The collar is made up of a framework with a plurality of discrete bodies spaced about the framework and a portion of each of the discrete bodies protrudes above the framework. | 04-21-2016 |
20160145944 | Water Post Hole Digging Tool - A water post hole digging tool is provided. The water post hole digging tool includes an elongate conduit member having an upper portion, a body portion, and a lower portion. The body portion may include a plurality of removably attached channel members. A handle is integrally attached to the upper portion of the elongate conduit member. A boring element is attached to a distal end of the lower portion. The boring element includes a concave expanding nozzle opening with a plurality of apertures for discharging water flow therefrom to change the contents of a desired hole from a solid to a slurry liquid mixture of water, sand, soil, and rocks. | 05-26-2016 |
