    Abstract: A completion assembly of a top packer and zone isolation packers separated by screens has a disconnect in a selected zone to be fractured or gravel packed that is armed before such a procedure starts. Initially when the assembly of the outer completion and the inner string are properly located and all the screens valved off, all the packers are pressure set and the packer set release device associated with each packer is armed. Before starting a fracturing or gravel packing operation from a given zone isolation packer, a disconnect for that zone packer is armed so that if the inner string sticks in that packer, the inner string is sheared and removed and another trip is used to grab the top packer and pick up. Such picking up releases all the packers down to the one armed disconnect. The disconnect releases bringing up the remnant of the inner string stuck in the packer just above the actuated disconnect.

  • Patent number: 8122960
    Abstract: Coiled tubing spears for retrieving a section of cut coiled tubing comprises a mandrel having attachment members, e.g., spears, at upper and lower ends for facilitating connection of the upper end of the mandrel to a spooled section of coiled tubing and the lower end of the mandrel to a section of cut coiled tubing disposed in a wellbore. Coiled tubing spears comprise one or more centralizers that are releasably secured to the mandrel. The centralizer(s) facilitate lining up a lower attachment member, or spear, with the bore of the section of cut coiled tubing so that the mandrel can be secured to the cut coiled tubing for retrieval. During retrieval of the cut coiled tubing, the centralizer(s) are released from the mandrel so that the mandrel and attachment members can continue through an injector head.

  • Patent number: 8002032
    Abstract: A hydraulic overshot apparatus designed to slide over plain end tubing and set by applying hydraulic fluid, under pressure, via a hydraulic setting port, into a center chamber which allows pressure to direct to two different piston areas. The setting piston compresses packer elements and tubing slips against the outer diameter (O.D.) of the tubing. The test piston compresses tubing test elements against the inner diameter (I.D.) of the tubing. The setting pressure is ported through the upper setting and test portion to allow pressure to move from the center chamber to the lower outer portion. The lower outer portion includes a body lock ring and a setting piston for setting the packer elements. Setting pressure moves the setting piston down through the body lock ring. As the setting piston moves down, it ratchets down through the body lock ring.

  • Publication number: 20110186286
    Abstract: A completion assembly of a top packer and zone isolation packers separated by screens has a disconnect in a selected zone to be fractured or gravel packed that is armed before such a procedure starts. Initially when the assembly of the outer completion and the inner string are properly located and all the screens valved off, all the packers are pressure set and the packer set release device associated with each packer is armed. Before starting a fracturing or gravel packing operation from a given zone isolation packer, a disconnect for that zone packer is armed so that if the inner string sticks in that packer, the inner string is sheared and removed and another trip is used to grab the top packer and pick up. Such picking up releases all the packers down to the one armed disconnect. The disconnect releases bringing up the remnant of the inner string stuck in the packer just above the actuated disconnect.

  • Publication number: 20110114317
    Abstract: A grapple for use in an overshot has a tension ring with a reduced helix diameter. However, the helix diameter is not reduced on either sides of the control finger slot to allow the grapple to remain in contact with the control. In the alternative, a composite helix member may be utilized. Another embodiment comprises the inclusion of expansion blades on the inner diameter (“ID”) of the tension ring which allow the grapple to expand substantially before the fish reaches the segments. Another embodiment provides for a control with an offset finger to allow the guide thread ID to be smaller than the bowl helix major ID. Yet another embodiment provides a spiral grapple having grooves along its axis to provide the ability to catch a larger range of fish.

    Abstract: A latching mechanism for selectively disengaging an upper pump from a motor in an ESP. The latching mechanism comprises barbs formed on an upper end of an upper shaft that are engaged by a tool to lift the upper shaft until a lower end of the upper shaft disengages from an upper end of a motor shaft. When the upper pump is disengaged from the motor shaft, only a lower pump is driven by the motor and flow of well fluid is circulated past the disengaged upper pump via a bypass line. The upper pump shaft may reengage the motor shaft if additional lift is required.

  • Publication number: 20110030955
    Abstract: A hydraulically powered fishing tool is provided for retrieving another tool or tubular stuck in a well. A tool housing is supported in a well on a work string, and the housing encloses a plurality of pistons (16, 28, 34) each movable in response to pressurized fluid transmitted through the work string. An anchor (52) axially fixes the position of the tool in the well, and a tool mandrel (40) is axially movable relative to tool housing when the anchor is set. A fishing device (82) engages the another tool or tubular, so that axial movement of the mandrel in response to the plurality of pistons dislodges the stuck tool or tubular.

  • Patent number: 7845431
    Abstract: A casing-while-drilling bottom hole assembly is releasably connected with a casing string. A retrieval tool is run into the casing string and latched to the bottom hole assembly. Slips are mounted to the retrieval tool, the slips being retracted during running in. Differential pressure moves the retrieval tool and bottom hole assembly upward, and the slips engage the casing string to prevent downward movement if the pressure differential drops too low. A flow passage extends through the retrieval tool and the bottom hole assembly. A check valve in the retrieval tool allows downward flow through the flow passage but prevents upward flow, so that fluid may be circulated through the retrieval tool and bottom hole assembly while suspended with the slips.

  • Patent number: 7690430
    Abstract: A tool for extracting well pipe casings resembles an enlarged pipe-thread tap. The tool is designed to be suspended under and driven by the traveling rotary table and hydraulic vertical drive system of a conventional drilling rig. By this means, well pipe casings are withdrawn from wells by engaging the tops of such well pipe casings, and unlike the prior art, which grapples well pipe casings at their very bottom, and at the end of a cable. Unlike withdrawing casing by a cable pull, wherein cables stretch and unstuck casings might launch like projectiles, the extractor tool manages to withdraw well pipe casing in a recoilless manner, which is more controlled, and safer.
