  • Patent number: 10141015
    Abstract: A reference block which is machined from a single body of material and is a single block with reference pins integral therewith is configured for use in a method of manufacturing a head suspension by laser-welding the flexure to the load beam at a first welding spot so that a tongue is pressed against a convex portion under predetermined load. The method includes steps of forming, before joining the flexure and load beam together, at least one positioning reference hole in each of the flexure and load beam within a circular range that is defined around the first welding spot with a radius equal to a distance between the first welding spot and the projection, laying the flexure and load beam one on another, inserting the reference pins of the reference pin block into the reference holes, and laser-welding the flexure and load beam to each other at the first welding spot.

  • Patent number: 9796877
    Abstract: The invention concerns a method of applying a coating in a liquid state to wellbore tubing, such as threaded connector parts or casing sections, before running the tubing downhole. The coating only cures while running downhole. The coating is an elastic curable coating composition, comprising a curable elastic thermosetting resin, a curing agent and a water-absorbing expansion agent. During make-up of a connector, the liquid coating composition acts as lubricant. When cured, the coating will swell when contacted with a wellbore fluid to ensure leak-tightness.

    Abstract: A system is provided for injecting coiled tubing (CT) into and out of a wellbore. In embodiments, separate injector and reel units are provided releasing constraints on CT size and length. The injector unit is fit with an extendible mast for handling larger bottom hole assemblies and fit with a rotating gooseneck for accepting CT from alternate arrangements of the reel unit. The mast is reinforced to resist CT loading. The capacity of the reel is maximized for the reel unit transport envelope. The reel is rotated using an offset drive engaging a bounding reel flange, such as engaging drive and bull gears. A generally radial displacement of the drive from the reel permits replacement of the entire reel.

Releasing the hoop force after insertion will release the elastic expansion and compression of the pipe bodies to abut the radial loading surfaces within the annulus for sharing elastic hoop stress resistance and thereby forming a greater effective wall thickness, capable of containing higher pressures than the conduit walls could otherwise bear.

The straight section is formed according to a formula Y=(1.26)(X)?0.13, where X is the wall thickness of a tubular and Y is the length of the straight section. The concave portion and the convex portion have an arc length extending the concave portion to a trailing edge of the tool. The concave and convex portions are radius-shaped. The arrangement of the shapes and their relation to each other reduces relatively high and low contact pressures and lessens the effects of axial bending in a tubular or a connection.

  • Patent number: 8763709
    Abstract: An assembly and techniques for employing multiple motors to drive an oilfield injector. The injector is configured to drive a well access line such as coiled tubing and the motors may be electric in nature. Additionally, the motors are configured to operate at substantially sufficient cooling speeds for electric motors. Nevertheless, the motors are coupled through a common differential mechanism such that a range of differential speeds may be derived via comparison of the operating speeds of the motors. Thus, a wide array of injection speeds may be employed without requiring the motors to operate at dangerously low speeds in terms of electric motor cooling.

  • Publication number: 20140158378
    Abstract: A radially expandable device including a tubular body formed from an extruded member having an extrusion direction. The extruded member is configured after extrusion of the extruded member so that the extrusion direction aligns with a resulting circumference of the tubular body during formation of the tubular body from the extruded member. The extruded member is formed from a material operatively arranged to disintegrate upon exposure to a selected borehole fluid. The tubular body is operatively arranged to be expanded from a first radial dimension to a second radial dimension. Methods of making and using a radially expandable device are also included.

  • Patent number: 8726985
    Abstract: A method is provided of radially expanding a tubular element (56) in a well-bore using an expander located in the tubular element, the expander (40) comprising an expansion member (48) and a plurality of segments (50) spaced in circumferential direction around the expansion member, the segments being movable between a radially retracted position and a radially expanded position by axial movement of the expansion member relative to the segments. The method includes a plurality of successive expansion cycles, wherein each expansion cycle comprises the steps of: (a) moving the expander (40) in axially forward direction through the tubular element (56) whereby the segments (56) are in the radially retracted position; and (b) radially expanding the tubular element by moving the segments to the radially expanded position by axially moving the expansion member relative to the segments.

  • Publication number: 20140131053
    Abstract: The invention provides a method and system for radially expanding a tubular element below a previous tubular element. The method includes: connecting a downhole section to an uphole section of the tubular element, the downhole section having a smaller diameter than the uphole section; bending a downhole end of the downhole section radially outward and in axially reverse direction to form a start expanded tubular section extending around an unexpanded part of the downhole section; arranging said start expanded tubular section at least partially within a downhole end of the previous tubular element; anchoring said start expanded tubular section to the previous tubular element; and increasing the length of an expanded tubular section of the tubular element by pushing an unexpanded tubular section downhole relative to said start expanded tubular section to expand the unexpanded tubular section by bending the wall of the unexpanded tubular section radially outward and in axially reverse direction.
