  • Patent number: 9299480
    Abstract: An umbilical assembly for supplying power to subsea equipment includes an electrical conductor to convey an electrical current to the subsea equipment. An insulator surrounds the conductor. A support member is positioned between the insulator and the conductor. The support member has either non-magnetic properties or low-magnetic properties because of its material composition. The support member is adapted to connect to a structure at the surface of the sea. The support member supports the weight of the conductor. The supporting of the weight of the conductor by the support member can be to reduce creep typically associated with the conductor supporting its own weight. The support member can be used to hermetically seal the conductor and prevent hydrogen migration along the conductor.

    Abstract: Well conduit system and methods using a first outer conduit wall and at least one second inner conduit wall positioned through a wellhead to define an annulus with radial loading surfaces extending across the annulus and radially between at least two of the conduit walls to form passageways through subterranean strata concentrically, wherein an inner pipe body of greater outer diameter is inserted into an outer pipe body of lesser inner diameter by elastically expanding the circumference of the outer pipe body and elastically compressing the circumference of the inner pipe body, using a hoop force exerted therebetween. 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.

At the wellhead, the lines communicate with an operating system, which can provide hydraulics, electric power, signals, or the like for downhole components. Beyond the wellhead, the concentric lines extend along the tubing to a manifold. The outer line sealably terminates at the manifold's inlet, while the inner conduit passes out an outlet with a sealed fitting to connect to a downhole component. A downhole line couples to an outlet of the manifold and communicates internally with the outer conduit terminated at the manifold's inlet. This downhole line can then extend to the same downhole component or some different component.

  • Patent number: 8272448
    Abstract: An electrical line for installation in a well for transmitting power to a well pump includes a string of coiled tubing. An electrical cable having insulated electrical conductors embedded within an elastomeric jacket extends longitudinally through the interior passage of the tubing. Body members are placed around the outer periphery of the electrical cable, and the body members are compressed onto the electrical cable through the use of an anchor assembly. The anchor assembly is held in a compressed state through the use of frangible support elements. Once the electrical cable is in place within the coiled tubing, the user applies an external force to cause the support elements to fail, thereby releasing the anchor assembly from its compressed state. The anchor assembly contacts the inner wall of the coiled tubing, such that the weight of the electrical cable is transferred to coiled tubing.

  • Patent number: 8225861
    Abstract: A swelling element on a packer has a trough formed on a longitudinal axis. The control line or cable or conduit that needs to run along the string where the packer is mounted is first wrapped in a preferably non-swelling underlayment that can be a loose scroll or have its seam sealed. A swelling cover is placed over the underlayment using a seam that can be longitudinal or spiral to allow rapid deployment. The covering assembly for the control line or conduit is placed in the slot of the swelling element of the packer. The line or cable continues out opposed ends and can be secured to the tubular string with clamps. The control line can be covered with a swelling material and forced into a groove that runs the length of the packer swelling element.

  • Patent number: 8196669
    Abstract: A method of drilling a wellbore (1) into an earth formation is disclosed. The method comprises arranging a drill string (6) and an expandable tubular element (8) coaxially in the wellbore, the drill string having an axially extending fluid passage (30), the tubular element surrounding the drill string and having a lower end bent (12) radially outward and in axially reverse direction so as to form an expanded tubular section (10) extending around a remaining tubular section of the tubular element, said lower end defining a bending zone of the tubular element, wherein an annular space is formed between the drill string and the remaining tubular section.

  • Patent number: 8176977
    Abstract: A method and apparatus for rapidly installing or withdrawing a sealing liner into or out of a subsurface well bore or borehole. An eversion aid, such as an open-ended cylinder, is engaged with the liner, the eversion aid serving to push the liner down the borehole during installation, and to assist in proper liner extraction during its withdrawal from the borehole. Water is transferred between the liner interior and the borehole outside the liner to regulate the disposition of borehole water, and to aid in proper sealing functions of the liner and to promote proper liner extraction during withdrawal.

  • Patent number: 8087461
    Abstract: Production logging apparatus and method are provided. The apparatus comprises a coupling module, an electronic module, a micro-winch, a docking station, and a micro-production logging tool. The coupling module provides mechanical support for the production logging apparatus below a pumping arrangement disposed in a wellbore, and allows flow to enter the pumping arrangement. The electronic module comprises a winch controller, a powering module and a telemetry module, and adapted to automate the micro-winch. The docking station comprises a latching mechanism for ensuring positive engagement of a micro-production logging tool with the production logging apparatus during docking. And the micro-production logging tool comprises at least one sensor and is coupled to the micro-winch by a cable for regular production logging runs to measure the evolution of well characteristics.

  • Patent number: 8083000
    Abstract: An apparatus and assembly create a seal in a wellbore around a cable or line. The assembly includes a longitudinal body and a swellable portion which comprises a material selected to increase in volume on exposure to at least one triggering fluid. The swellable portion has a formation open to the longitudinal surface of the body which provides a pathway for a cable or line to extend through the swellable portion, and an insert of swellable material. The insert may partly or fully enclose or encapsulate the cable or line. a formation which is open to an outer longitudinal surface of the body.
