  • Patent number: 10006264
    Abstract: A whipstock assembly has a whip, a packer, and an anchor. The packer connects between the whip and the anchor and sets after the anchor is set. The anchor can be set mechanically or hydraulically. To communicate hydraulic pressure to the hydraulically-set anchor, the packer can have an internal bypass for communicating fluid or for passing a hydraulic line from the whip to the anchor. The packer is set mechanically with set down weight applied from the whip via a setting tool or the like. The packer sets eccentrically in the casing and acts as a fulcrum to push the tip of the whip against the inside of the casing.

  • Patent number: 9879485
    Abstract: A stabilizer for passing through a restriction includes a tubular body having a bore therethrough; a rigid blade disposed on the tubular body; and a deformable blade disposed on the tubular body, wherein the deformable blade includes a geometric profile configured to preferentially bend the deformable blade in one direction when the deformable blade encounters the restriction, and wherein the deformable blade has a height greater than a height of the rigid blade. In one example, the deformable blade is offset from a radial axis.

  • Publication number: 20160076327
    Abstract: A pulling tool deploys on a workstring to retrieving a well component, such as casing or a liner, stuck downhole. The tool has an anchor, a puller, and an implement. The implement is supported on the end of the puller and engages the component. Hydraulic pressure supplied downhole moves at least one puller piston coupled to the implement along a piston mandrel to pull the implement and component. An anchor mandrel coupled to the workstring and the piston mandrel anchors the pulling tool downhole. The anchor has slips disposed on the anchor mandrel that engage in surrounding casing when an anchor piston disposed on the anchor mandrel is hydraulically actuated with the communicated pressure.

  • Patent number: 7264067
    Abstract: A method and apparatus for drilling and completing multiple wellbores from a single drilling rig and from within a single wellhead is provided. In one embodiment, a template is disposed at a predetermined location downhole within a casing. In one aspect, a first casing string is lowered with the template to the predetermined location and disposed within a first wellbore. A second wellbore may be drilled through a bore in the template. A second casing string may then be lowered through the bore into the second wellbore. In another embodiment, at least two wellbores are drilled and completed from a surface casing having a crossover portion.

  • Patent number: 6923274
    Abstract: An apparatus for drilling one or more holes at an angle to a wellbore. The apparatus includes a tubular housing defining one or more openings. Each opening is configured to provide an exit through which a drilling assembly drills to form a hole at an angle to the wellbore. The apparatus further includes one or more deflectors. Each deflector defines a surface for guiding the drilling assembly through an opening, and each deflector is positioned inside the tubular housing such that the surface is facing the opening. The apparatus further includes an anchor having a bottom portion attached to a top portion of the tubular housing and having a top portion configured to be removably fixed to a conveyance tubular.

  • Patent number: 5246069
    Abstract: Well apparatuses with device for preventing their relative rotation with respect to adjacent well apparatuses and anti-rotation devices for well apparatuses, including, but not limited to, plugs, float shoes, float collars, jars, and clutch devices for packers. In one embodiment self-aligning non-rotation devices are provided with body members having protrusions extending from recesses therein, the protrusions and recesses configured and disposed so that two opposed devices which initially misalign will co-act to align themselves. In another embodiment an intentional "sloppy fit" is provided between two opposed devices to facilitate device contact and co-action. In various embodiments unwanted separation of two devices is prevented due to the configuration of protrusions.

  • Patent number: 5113940
    Abstract: Well apparatuses with device for preventing their relative rotation with respect to adjacent well apparatuses and anti-rotation devices for well apparatuses, including, but not limited to, plugs, float shoes, float collars, jars, and clutch devices for packers. In one embodiment a non-rotation device has a main member with a recess on which are disposed a plurality of teeth with a load member adjacent the teeth for bearing a load put on the device and for isolating the teeth from the load, the teeth extending beyond the recess. In one embodiment the teeth are configured, disposed, and profiled to facilitate their interengagement with other teeth and to contain between them foreign objects which might impede proper interengagement. In various embodiments plugs are provided with such anti-rotation devices. In various embodiments the load member is a continuous circular ring disposed about the apparatuses outer periphery or around the opening of a channel through the device.

  • Patent number: 4508167
    Abstract: An annular packoff assemblage is provided for selective engagement with any one of a plurality of casing seal bore receptacles spaced along a casing string. The packoff assemblage includes an upper latching assemblage for cooperation with an upwardly facing no-go shoulder providing in the selected seal bore receptacle, an intermediate annular sealing assemblage for establishing sealing integrity between an inner mandrel and the polished internal bore of the selected seal bore receptacle, and a lower latching assemblage movable into latching engagement with the downwardly facing surface provided at the end of the seal bore of the casing receptacle. In two embodiments of the invention, upward movement of the tubing string, followed by a turning movement and a downward movement will effect the releasing of both the upper and lower latching elements to move outwardly into latching engagement with the respective surfaces in the selected casing receptacle.

  • Patent number: 4405017
    Abstract: This invention relates to an expendable tool, such as a plug assembly, which may be locked within a tubular member, such as a packer assembly, located within a well casing, and a method of locating and releasing same. The plug assembly comprises a main housing adapted to support a plurality of circumferentially spaced, radially retractable locking segments. A longitudinally extending mandrel is slidably mounted within the housing and is axially shiftable from an first position, wherein the mandrel maintains the locking segments outwardly within a cooperating groove formed in the packer assembly, to a second position, wherein the locking segments are permitted to move out of engagement with the well packer. A collet sleeve is secured to the mandrel by a shear pin and maintains the mandrel in the upper position. When it is desired to release the plug from the packer assembly, an actuating sleeve is attached to the lower end of a tubing string and run down the well casing to be engaged by the collet sleeve.
