  • Patent number: 10808507
    Abstract: A technique facilitates actuation and use of a liner hanger in a wide variety of environments. Depending on the application, the liner hanger may be conveyed downhole within a casing located in a wellbore. The liner hanger comprises slips which may be set against the casing by applying a pressurized fluid through a liner hanger port to a liner hanger actuator. After the slips are set, the liner hanger may be actuated to form a metal-to-metal seal which blocks further fluid flow through the port, thus isolating the port during subsequent downhole operations.

    Abstract: Devices for controlling the flow of fluids past a location in a wellbore and methods for using such devices are disclosed. Embodiment devices are configured such that the throughbore is maximized because of the devices' thin cross sectional length. The devices disclosed may use balls, darts or other plugs to seal against a plug seat and prevent flow therethrough, external seals prevent flow therearound and gripping elements, such as slips, prevent movement of the device within the well. Relatively high pressure rating may be accomplished with such thin cross sections by keeping the length of mandrel wall exposed to such pressures short. Some embodiment devices may have a plug seat that is integral, at least in part, with a setting ring and/or have a setting ring that is of one piece with the mandrel.

  • Patent number: 8567510
    Abstract: Pressure actuable downhole tool such as a packer and a method for actuating the same typically uses a control line to trigger a configuration change in the tool in which a communication line is opened between the throughbore of the tool and apressure responsive actuator, allowing the pressure responsive actuator to be set by downhole fluid pressure applied via the throughbore. Thus the pressure from the control line is used to trigger actuation of the tool, but the throughbore pressure is used to set the tool. The advantage of this activation mechanism is that the tool can be set even when pressure supplied by the control line is insufficient to fully actuate or set the tool, and in certain embodiments, the tool can be set using much higher tubing pressure than could be supplied through the control line, thereby allowing more reliable and instantaneous setting than tools set using control line pressure alone.

Fluid communication through the piston and between its upper and lower sides is controlled by a normally shut valve in the passageway.

  • Patent number: 8151895
    Abstract: Systems and methods for patching a desired section of wellbore casing or another tubular member. A patch assembly is provided which includes a tubular patch sub which is radially surrounded by an inflatable boot. A setting tool is used to set the patch assembly within the casing. The setting tool includes a heated barrel that contains eutectic material in liquid form. When actuated from the surface, eutectic material is flowed from the setting tool to the boot of the patch assembly. The eutectic material inflates the boot to secure the patch sub at a desired location within the wellbore.

  • Patent number: 8042574
    Abstract: The present invention relates to an arrangement for use with a plug (1) for sealing against an inner wall of a pipeline (30), comprising a main body and sealing means, which sealing means comprises an annular packer element (7), arranged between two relative movable body elements (5,6) of the main body actuated by actuation means, where the movable elements form surfaces (500,600) in abutment against the packer element (7). The packer element (7) comprises a radially inner section (705) which is mainly incompressible in a direction transverse to a circumferential direction and where sections of the two surfaces (500,600) in abutment against the inner section (705) of the packer element (7) in a retracted position, forms different angles in relation to an axis in radial direction in relation to a longitudinal axis of the plug.

  • Publication number: 20110174504
    Abstract: Methods of actuating a well tool can include releasing chemical energy from at least one portion of a reactive material, thermally expanding a substance in response to the released chemical energy, and applying pressure to a piston as a result of thermally expanding the substance, thereby actuating the well tool, with these steps being repeated for each of multiple actuations of the well tool. A well tool actuator can include a substance contained in a chamber, one or more portions of a reactive material from which chemical energy is released, and a piston to which pressure is applied due to thermal expansion of the substance in response to each release of chemical energy. A well tool actuator which can be actuated multiple times may include multiple portions of a gas generating reactive material, and a piston to which pressure is applied due to generation of the gas.

  • Publication number: 20100300703
    Abstract: Pressure actuable downhole tool such as a packer and a method for actuating the same typically uses a control line to trigger a configuration change in the tool in which a communication line is opened between the throughbore of the tool and a pressure responsive actuator, allowing the pressure responsive actuator to be set by downhole fluid pressure applied via the throughbore. Thus the pressure from the control line is used to trigger actuation of the tool, but the throughbore pressure is used to set the tool. The advantage of this activation mechanism is that the tool can be set even when pressure supplied by the control line is insufficient to fully actuate or set the tool, and in certain embodiments, the tool can be set using much higher tubing pressure than could be supplied through the control line, thereby allowing more reliable and instantaneous setting than tools set using control line pressure alone.

    Abstract: Methods and apparatus to apply axial force to a packer in a downhole tool are described. In one described example, an apparatus to apply an axial force to an inflatable packer associated with a downhole tool includes a sleeve slidingly coupled to a body of the downhole tool and an end of the packer. An inner portion of the sleeve is sealed against the body of the downhole tool to form a chamber, and the chamber is fluidly coupled to a pump associated with the downhole tool to receive a pressurized fluid to cause the sleeve to apply an axial force to the packer.

    Abstract: A multi-functional completion tool which may be lowered into a wellbore coupled to a length of tubing, and then utilized to test various lengths of the tubing at pressure. The tool may also function as a positive plug and may also be used to set the packer, and is also useable as a tubing self-filling tool. Various retention elements are disposed within the tool and configured to release at predetermined pressures, or within predetermined ranges of pressure, thereby transforming the tool from a first configuration to a second configuration depending on the desired function. The tool may also contain a pressure-regulating assembly for regulating the differential pressure across the assembly. The tool may also include an indicator assembly for confirming that the tool has entered a plugging configuration, typically by altering a pressure within the tubing, such alteration being detectible at a surface location.
