    Abstract: A hanger assembly for supporting a tubular member within an outer well member includes a slip bowl that is moveable between an expanded condition with an enlarged diameter and a contracted condition with a reduced diameter, and has a downward facing slip bowl shoulder on an outer diameter of the slip bowl. Slips with teeth on an inner diameter surface are carried by the slip bowl. The slips are moveable between a retracted position, and an extended position where the teeth protrude radially inward from the inner diameter of the slip bowl. A false bowl has a lower upward facing false bowl shoulder located on an inner diameter and is sized to selectively engage the downward facing slip bowl shoulder. The false bowl also has a downward facing landing shoulder located on an outer diameter that is sized to selectively engage a support shoulder of the outer well member.

  • Patent number: 9303465
    Abstract: A mule shoe assembly for use in directional drilling which advantageously has releasable locking means to free the directional orienting tool from engagement with the outer mule shoe in situations where the drill bit may become stuck. The releasable locking means comprises a moveable pin which engages an aperture. A first configuration utilizes detent means and spring biasing of the pin. In a second configuration, the pin is adapted for locking engagement by pressurized downhole drilling mud, and may be disengaged from the aperture when pressure from drilling mud ceases. In a preferred embodiment the pin both has detent means and is spring biased, and also relies on drilling mud pressure to remain in locking engagement. The pin may be disengaged upon removal of drilling mud pressure and application of a positive separation force between the directional measurement tool and associated inner tool member, and outer mule shoe member.

  • Publication number: 20150144330
    Abstract: A method is for use with subterranean formations, such as oil and/or gas reservoirs. In some examples (e.g., production examples), the method improves the production from that formation. Some of the examples of the method describe selecting both an exertive force (e.g., a pressure) to apply at a wellbore, but together with a drawdown pressure at the wellbore to modify operations (e.g., improve production) at that subterranean formation. The selection of one or both of the exertive force and drawdown pressure may be based on the downhole environment at that wellbore, which can include the porosity and/or permeability of a near-wellbore formation radially surrounding a wellbore. The exertive force and drawdown pressure may be specifically selected to modify the porosity and/or permeability of the near-wellbore formation.

  • Publication number: 20140054043
    Abstract: A space filler material is used to prevent accumulation of debris that could later foul the operation of adjacent moving parts. In one application a void space that is subsequently closed by actuated parts is initially filled with a material that is highly compressible and has voids that allow it to compress without undue resistance to part movement when the void volume is reduced. Ideally, the pores or voids in the material itself are small enough to keep most if not all the debris from entering and making the space filling material too rigid to collapse under part movement. In an alternative application, the material can be in an annular space such as a seal bore and it can keep debris from getting past the seal bore while allowing hydrostatic pressure across itself thereby helping it to maintain its position until moved such as by shifting of an inner string to which it is attached.

  • Patent number: 8640769
    Abstract: Concentric control lines have an outer line disposed about one or more inner lines. Encapsulated together, the lines only require one penetration through the wellhead to extend downhole. 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.

    Abstract: A downhole device with compressive layer at the surface thereof. Such devices may be particularly well suited for survivability in the face of potentially long term exposure to a downhole environment. Techniques for forming protective compressive layers at the surfaces of such devices may include positioning devices within a chamber for bombardment by high frequency particles. As a manner of enhancing the compressive layer thickness and effectiveness, low temperature conditions may be applied to the device during the high frequency treatment.

  • Patent number: 8561694
    Abstract: An apparatus monitors a production flow from a gravel pack into a tubular sand screen disposed concentrically around downhole production tubing in an oil or gas well. A tubular sample layer is disposed concentrically around the sand screen to be exposed to the radial production flow in use. The sample layer is electrically insulated from the production tubing in use. An erosion sensor provides a signal which varies in dependence upon an electrical resistance of the sample layer, which is related to the erosion of the sample layer. An apparatus also monitors a substantially longitudinal production flow through downhole production tubing in an oil or gas well. A method and apparatus are used to monitor the condition of a gravel pack within an oil or gas well. Other methods monitor temperature or pressure conditions within an oil or gas well.

  • Patent number: 8448713
    Abstract: An inflatable packer contains a reactive metal in an annular space between the mandrel and the element. A fluid is admitted into the annular space to start a reaction that gives off gas. The generated gas fills the annular space and inflates the element in the process. The actuating fluid can be water and the off gas can be hydrogen. The volume of the reactants can also increase as they swell in the reaction that generates the gas. A valve arrangement associated with the mandrel retains the gas pressure and prevents over-pressurization. The packer can be set in a surrounding tubular or in open hole.
