    Abstract: A method of downhole operations with a wireline deployed tool that has become stuck downhole. The wireline is selectively detached from the stuck tool, and a tubular is attached to a coupling provided with the tool. The tool is unstuck by applying upward and downward forces to the tool with the tubular. The coupling further provides communication between a line in the tubular and the downhole tool, thereby providing communication between the tool and surface. Thus, after unsticking the tool, wellbore operations can continue with the tool attached onto the tubular.

  • Patent number: 7364448
    Abstract: A connector may include first and second connector portions being movable between unmated and mated positions. First and second bladders may be in respective first and second connector portions and cooperate therewith so that opposing ends of the first and second bladders are urged together and moved from a closed to an open position as the first and second connector portions are moved from the unmated to the mated position. At least one of the first and second connector portions may define a circular constriction for closing an end of a respective bladder into a circular peripheral shape when the first and second connector portions are in the unmated position. One or both of the bladder ends may define a generally rectangular aperture when in the open position.

  • Patent number: 7244132
    Abstract: A connector may include first and second connector portions movable between unmated and mated positions; first and second bladders carried by respective connector portions, and each having an end movable between a closed position and an open position; and an interlocking assembly including first and second portions carried by respective connector portions and being movable between a released position, permitting opposing ends of the bladders to move apart, and an interlocked position, holding the opposing ends of the bladders together. The interlocking assembly may hold the opposing ends of the bladders together as the opposing ends of the bladders move from the closed position to the open position and/or as the opposing ends of the bladders move from the open position to the closed position. Also, the interlocking assembly may provide a positive drawback between its first and second portions during movement from the interlocked position to the released position.

  • Patent number: 7195504
    Abstract: A high-pressure connector for an electrical power cable segment having a central stranded conductor encased in a polymeric insulation jacket with an interstitial void volume in the region of the conductor. The connector confines a fluid within the interstitial void volume at a residual pressure above atmospheric, but below the elastic limit of the insulation jacket. A housing interior chamber receives the conductor in fluid communication with the interstitial void volume. Some embodiments have the chamber sized to receive and overlap a portion of the insulation jacket with a housing end portion swaged thereto. A seal seals the insulation jacket with respect to the housing and a retaining member secures the cable segment to the housing to prevent pushback of the insulation jacket at the residual pressure.

  • Patent number: 6932636
    Abstract: An electrical penetrator connector has a fixed coupler pin unit which incorporates a pin having a conductive element. A reciprocatable component includes a housing defining a bore into which the pin may be inserted. Within the bore is a retractable shuttle pin. A chamber contains dielectric fluid. A flow path for the dielectric fluid is configured to move the fluid past a contact in the bore which is to touch the contact on the pin. The dielectric fluid circulates round the flow path every time the pin is inserted into the bore.

  • Publication number: 20040058575
    Abstract: An electrical connector and method of making the electrical connection are disclosed for use in particularly arduous conditions, such as down hole oil production applications. The invention provides high electrical integrity with an ability to accommodate steady and/or fluctuating mechanical forces placed via the cable into the connector. Synergy between the mechanical and electrical aspects of the design is taught in which an insulating member, fitted with annular upstands, co-operates with a mechanically soft, essentially incompressible, insulating substance (gel) to cause vibrations in the cable to be dissipated over a length of the insulated cores inside the connector rather that at a single point where it would cause the core to fracture. In addition, annular collars of the gel are provided between the insulating member and the crimped pin-core connections and between the annular upstands and insulated cores to give further cushioning.
