The anchor includes a plurality of anchoring members each rotatable about a fulcrum between a locking position and a non-locking position. The anchor housing has a groove formed between adjacent anchoring members through which a string may be run to access below the anchor when the anchor is installed.

Abstract: A high-axial load bearing assembly is provided for use with a radially expandable tool such as an expandable liner hanger. Exemplary embodiments of axial load bearing assemblies operate independently of external casing pressure and internal tubing pressure. The assemblies do not rely on movable slips or the physical characteristics of the sealing members to grip the casing and bear the axial load. The gripping and sealing functions are largely separated between gripping and sealing sub-assemblies. Hardened metal features which undergo radial expansion during deployment are provided with expansion stress-relief features.

Abstract: An actuation tool uses a lock that when released allows a moving magnet to move into position to repel another magnet. Alternatively a magnetic field can be triggered in a stationary magnet such as one delivered on wireline, for example, to accomplish tool actuation. The repelling force on the second magnet moves it away from a locking position to allow another lock to retract and release the stored potential energy, where the release of the potential energy creates kinetic energy to drive an actuation assembly to set the tool. In a preferred application the tool can be a liner hanger. The release device can be a selectively energized electromagnet or a solenoid that shifts at least one magnet into alignment with at least one second magnet so as to defeat the second magnet from effectively supporting dogs that retain the potential energy whose movement can set the tool.

Abstract: A tubing anchor for anchoring and catching well equipment in a well conduit to arrest movement in both longitudinal directions and rotation in a first direction. A mandrel connected to the equipment has in one embodiment C or reverse C-shaped grooves when viewed in front elevation for slideably receiving respective pins from a drag body on the mandrel. A slip retainer on the mandrel houses slips for selectively engaging and disengaging the conduit. An initial pull of the mandrel causes the pins to move the drag body toward the slip retainer driving the slips outward to grip the conduit. Rotation of the mandrel in the first direction sets the anchor to arrest movement. Further pulling and a reversed turn of the mandrel maintains the set position. A spring biases the slips outward to maintain their set to catch the well equipment in the event of a break in the string above the anchor.

Abstract: A method of lining a wellbore includes deploying a BHA into the wellbore using a conveyance. The BHA includes setting tool, an anchor, and an expandable tubular. The method further includes pressurizing a bore of the setting tool, thereby releasing the anchor from the setting tool. The method further includes pulling the conveyance, thereby: extending the anchor into engagement with a casing of the wellbore, pulling an expander of the setting tool through the expandable tubular, and expanding the tubular into engagement with an open and/or cased portion of the wellbore and retracting the anchor.

Abstract: There is provided a system and method for installing a wellhead component in a single trip. Generally, a wellhead component may be run into a wellhead using a running tool. The running tool may then be retrieved from the wellhead and replaced with a locking tool, which is also run into the wellhead. Additional tools may be used to over-pull the wellhead component and to cementing the wellhead component in place. The process of retrieving and running tools into the wellhead is both time-consuming and costly. Accordingly, the disclosed embodiments include a one-trip tool configured to run a wellhead component into a wellhead, engage an internal coupling to lock the wellhead component in place, over-pull the wellhead component to ensure the internal coupling was properly engaged, and cement the wellhead component in place within the wellhead.

Abstract: A torque anchor for anchoring well equipment in a well conduit to arrest movement in both longitudinal directions and rotation in a first direction, but not rotation in an opposed second direction. A mandrel connected to the equipment has L-shaped grooves for slideably receiving respective pins from a drag body on the mandrel. A slip retainer on the mandrel houses slips for selectively engaging and disengaging the conduit. An initial pull of the mandrel causes the pins to move the drag body toward the slip retainer driving the slips outward to grip the conduit, and rotation of the mandrel in the first direction sets the anchor to arrest movement. Further pulling maintains the set position. The anchor is unset by releasing pull, rotating the mandrel in the second direction, and pushing the mandrel to disengage the slips. Alternate unsetting requires increased pull beyond the shear resistance of the slip retainer.

Abstract: A tubular locking system comprises a first wellbore tubular, an internal locking feature disposed on an inner surface of the first wellbore tubular, a second wellbore tubular, where at least a portion of the second wellbore tubular is disposed within the first wellbore tubular, a compression sleeve coupled to the second wellbore tubular, a collet coupled to the second wellbore tubular below the compression sleeve, and a shifting sleeve disposed within the collet.

Abstract: Elastodynamic waves are generated by a tool having a hammer rotatably connected with a housing by a first hinge and an actuator arm rotatably connected with the hammer by a second hinge. An axial force applied to the actuator arm by a drive shaft and spring is translated and amplified to a radial impact force by rotation of the hammer around the first hinge. The tool may also include a stabilizer arm connected to the actuator arm by a third hinge, and connected to the housing by a fourth hinge. The housing may be an acoustic wireline tool cylinder having an opening that permits the hammer mass to extend outside the housing when rotated in a first direction. The housing may also include a second opening that permits the hammer mass to extend outside the housing when rotated in a second direction, and a third opening that permits the hammer mass to extend outside the housing when rotated between the first and second openings.

Abstract: An anchoring sub used in combination with hydrocarbon exploration and production tools, such as perforating guns and logging devices, within a wellbore. The anchor sub is reversible and includes a mandrel, a slip assembly and a slip cone, where the slip assembly selectively travels up and down the mandrel and is able to mate with the slip cone. The anchor sub secures itself to the inner circumference of a wellbore when the slip assembly is mated with the slip cone. Mating and de-mating of the slip assembly with the slip cone is accomplished by selective up and down movement of the anchor sub.

Abstract: An anchoring tool anchors a tubing string within a surrounding well casing against rotation in either clockwise or counter clockwise directions. The tool includes a tubular housing for connection in line with the tubing string. A fixed jaw is fixedly mounted on the tubular housing and a floating jaw is supported for full rotation about the tubular housing past the fixed jaw. When the floating jaw engages the well casing, the overall diameter of the tool is varied as the fixed jaw is rotated with the tubing string relative to the floating jaw and the surrounding well casing. The tool can be used for anchoring the tubing string to the well casing in either direction while the tool remains down hole in the well casing due to the floating jaw being rotatable past the fixed jaw.

Abstract: A method and an apparatus for connection with a tubing string for use in a wellbore for regulating the flow of a fluid within a wellbore annulus between the tubing string and the wellbore. The apparatus includes a tubing rotator and at least one packer valve for connection with the tubing string, wherein the packer valve is actuatable through rotation of the tubing string by the tubing rotator. Rotation of the tubing string actuates the packer valve between a closed flow position wherein the packer valve substantially seals the wellbore annulus and an open flow position wherein the flow of the fluid is permitted through the wellbore annulus. The method includes the steps of suspending the tubing string in the wellbore by the tubing rotator, connecting the packer valve with the tubing string and rotating the tubing string by the tubing rotator in the first direction to actuate the packer valve to the closed flow position.

Abstract: A mandrel-operated torque roller anchor for insertion into the casing of a well, which when set resists axial movement and prevents rotation of itself and the string above it in one direction, but permits such motion when rotated in the other direction. The anchor comprises a central mandrel and a slip cage. The slip cage has a number of elongated slots. A number of drag slips rest on the mandrel within the slip cage and provide limited outward movement, through the slots, to bear against the casing. Each drag slip has a surface with wickers to grip the casing and set the anchor, and an adjacent unwickered drag portion to bear against the casing to allow the mandrel to rotate relative to the slips and cage, but permit axial movement of the string. Slots running through the drag portion of the slip provide flow around the anchor. Biasing elements extend between the mandrel and an interior surface of each slip to force the drag portion of the corresponding slip against the casing when in an unset position.

Abstract: A latching device to be used with a cement squeeze packer and a stinger is disclosed. The latching device enables an operator at the surface of an oil or gas well to open and close the squeeze packer valve without the risk of pulling the stinger out of the packer. The latch assembly is installed on the stinger assembly and is provided with a plurality of radially flexible fingers that engage the uphole end of the packer mandrel. Preferably, a series of ribs on both the latch and the uphole end of the mandrel are engaged when the stinger assembly descends into the hole and the stinger enters the packer. These ribs prevent the stinger from coming out of the packer until a predetermined tensile force is applied.

Abstract: A device anchors a tubing string within a stationary well casing against rotation in a predetermined angular direction. A housing is installed in-line in the tubing string. Anchoring mechanisms are spaced circumferentially about the housing. Each anchoring mechanism includes a recess and an anchoring member free-floating within the recess. The anchoring member has a fulcrum portion and a bite portion external to the recess. Retaining rings partially overlaying the recess prevent the anchoring member from escaping. A spring urges the anchoring member against the retaining rings and urges the bite portion to contact the well casing such that rotation of the tubing string displaces the anchoring member. Rotation of the tubing string in the predetermined direction seats the fulcrum portion in a seating structure within the recess and causes the bite portion to bite into the well casing, locking against further rotation.

Abstract: Designed primarily for use in the production of heavy and medium oil in conjunction with a screw-type pump in relatively shallow or medium wells, the device comprises an inner mandrel within an outer casing situated below the pump and connected to the pump casing and prevents right-hand rotation in the event that the torque reaction of the pump increases due to sand, for example, and attempts to rotate the pump stator together with the production string tubing, but at the same time allows vertical movement of the string to take place for withdrawal purposes.
