    摘要： A tool that is usable in a well and may include an operator, a switch, a resilient device and an indexer. The switch may be configured to selectively communicate a first force to the operator, thereby actuating the tool. The resilient device may exert a second force. The indexer may cycle through a sequence of positions in response to alternating between the second force and a third force. The sequence includes a predetermined position configured to actuate the switch, thereby communicating the first force to the operator to actuate the tool.

    摘要： A method of completing a wellbore includes the steps of connecting an isolation tool to a conveyance, the isolation tool including a tubular base member having an internal bore and an outer housing forming a first chamber and a second chamber separated by a wall; the first chamber having a first inlet port in communication with the internal bore and a first outlet port formed through the housing; the second chamber having first inlet port in communication with the internal bore and a second outlet port formed through the housing; a first material disposed in the first chamber; and a second material disposed in the second chamber; running the conveyance into the wellbore, an annulus formed between the isolation tool and sidewall of the wellbore; and activating the isolation tool to form a barrier to fluid flow in the annulus.

    摘要： A system for pressure testing the seals and fittings associated with at least one communication line passing through a well tool mandrel, each communication line housed within a communication line conduit defined through the well tool and sealingly engaged to each end of its corresponding communication line conduit by way of a fitting and the fittings also sealingly engaged to the communication line conduit. The system generally comprises a testing conduit, a testing passageway system, and a testing plug. The testing conduit is defined in the well tool mandrel. The testing passageway system is defined in the well tool mandrel and provides fluid communication between the testing conduit and the fittings and seals associated with each of the communication line conduits. The testing plug provides fluid communication between a pressure testing source and the testing passageway system. A pressure source is operatively connected to the testing plug, and pressurized fluid is guided from the testing plug, through the testing passageway system, into the communication line conduits, and into contact with the with the fittings and seals associated with each of the communication line conduits. Any leaks discovered as a result of this pressurization indicate the presence of a faulty engagement of the fittings or seals associated with the communication line conduits. This operation is performed prior to inserting the well tool in the well bore and without the pressurization of the well tool internal bore.

    摘要： A technique is provided for forming a gravel pack at a well zone. A completion assembly is positioned in a wellbore and cooperates with a service tool engaging the completion assembly. The completion assembly comprises a completion assembly central bore. A return is located radially outward of the central bore at a specific well zone or zones and comprises a flow path for returning a carrier fluid. The location of the return allows flow of the returning carrier fluid to remain outside of the completion assembly central bore at a specific well zone or zones.
