  • Patent number: 10619470
    Abstract: Hydrajetting assemblies provide data communication and the ability to jet abrasive fluid at pumping rates exceeding the abrasiveness rating of downhole devices. A hydrajetting tool includes jetting nozzles to jet a fluid into a subterranean formation. A capillary to house a data communication line is positioned along the housing of the tool. The communication line in run through the capillary and couples to a downflow sensing device having a fluid flow prevention device thereon. During perforating, the fluid flow device is closed, thus causing the pressurized abrasive fluid to jet out the nozzles. Since the sensing device is positioned downflow of the hydrajetting tool, the abrasive fluid may be pumped at a rate exceeding the abrasiveness rating of the sensing device. Also, real-time data may be communicated from the sensing device using the communication line.

  • Patent number: 10280686
    Abstract: A method of performing coupled drilling, flushing, and slotting operations on a coal seam, which has a high gas content and prone to bursts, is described herein. The method is aimed to relieve pressure and increase permeability when drilling a through-seam borehole to pre-drain gas belts in a coal mine roadway. The pressure relief and permeation method of the present invention adjusts the water jet water inlet pressure in different stages according to the different positions of the drilling construction, and controls the water during drilling. At drilling stage, the jets are respectively subjected to low-pressure water flow drilling and medium-pressure water flow flushing. When withdraw drilling, the high-pressure water flow slotting is carried out. By doing so, the pressure is relieved in a low, medium, high stepwise manner.

Upon contact with the curved face of the whipstock, the jetting hose is re-directed through a window in the production casing. Hydraulic fluid is injected under pressure through the hose to provide hydraulic jetting. The hose is directed through the window and into the formation to create a lateral borehole extending many feet outwardly into a subsurface formation.

  • Patent number: 8256533
    Abstract: A distance holder for connection to, and rotation with, a drill string in an earth formation drilling device arranged to supply a jet of abrasive fluid for the purpose of providing a borehole by removing earth formation material through abrasion, comprises a housing with a chamber which is essentially rotational symmetric and which is to face the earth formation material, and a jet nozzle which arranged for discharging a jet of the abrasive fluid in the chamber, the housing comprising at least one slot for allowing the abrasive fluid to leave the chamber. The slot is continued over the housing outer surface so as to counteract rolling motions of the particles which are comprised in the abrasive fluid.

  • Publication number: 20120160568
    Abstract: The present invention generally relates to an abrasive jet drilling assembly. In one aspect, a resettable circulation tool for use in an abrasive jet drilling assembly is provided. The resettable circulation tool includes an inner body having a first port in fluid communication with a bore. The resettable circulation tool further includes an outer body having a second port. Additionally, the resettable circulation tool includes a cam member configured to move along one or more slots, wherein the bodies move relative to each other to selectively align and misalign the first port and the second port as the cam member moves along the slots. In another aspect, a method of using a resettable circulation tool disposed in an abrasive jet drilling assembly includes moving the first and second ports into and out of alignment.

  • Publication number: 20120160567
    Abstract: A jet drill coupled to a distal end of a flexible jet lance is lowered into a well casing and advanced through a curved passage formed in a deflection shoe oriented to direct the jet drill through an orifice milled in the well casing. The jet drill is actuated with a pressurized fluid produced by a pump on the surface that is conveyed through a high pressure hose that runs through the flexible jet lance. Force transmitted through a thrust liner of the jet lance advances the jet drill while the lateral bore is being drilled. The thrust liner comprises helical coils of steel wire providing a high elastic modulus and buckling resistance, even while passing through the curved passage. Tension cables in the jet lance maintain tension on the thrust liner and enable the assembly to be pulled from the lateral bore and well.

  • Patent number: 8186459
    Abstract: A flexible hose and a method of well drilling are provided herein. In embodiments, the hose includes a forward end, a rearward end, a thruster port and a shut-off valve. The rearward end is configured to be in fluid communication with a source of high pressure drilling fluid. The thruster port is located upstream of the forward end. The thruster port is configured to emit drilling fluid in a substantially rearward direction. The shut-off valve is located between the forward end and the thruster port and is configured to shut off flow of drilling fluid downstream.

  • Patent number: 8141659
    Abstract: A method and apparatus for penetrating a side of a well casing and/or drilling into earth strata surrounding the well casing, utilizing a rotating fluid discharge nozzle, and an abrasive introduced into the fluid downstream of apparatus for rotating the nozzle. Apparatus for rotating the nozzle can include a motor operable by pressurized fluid, or another suitable rotating power source The introduction of the abrasives will not adversely affect or harm the apparatus for rotating the nozzle, yet will provide the enhanced drilling capability. The abrasive stream can be used for drilling or cutting through a metal well casing, as well as cement and the adjacent strata.

    Abstract: 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.
