Abstract: A plug assembly includes an expandable assembly, a locking ring and a cup. The expandable assembly is adapted to be deformed radially over the locking ring and the cup. The locking ring has a stopping inner surface. The plug assembly is used with one or more untethered objects, the untethered objects having an outer surface adapted to couple with the cup, and the cup having an outer surface adapted to couple with the stopping inner surface of the locking ring. The combination of cup and untethered objects is also adapted to contact an inner surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause the longitudinal movement of the cup and untethered objects while contacting the inner surface of the plug assembly until the cup contacts the stopping inner surface of the locking ring.

Abstract: Methods and apparatus to install a plug on a reusable auto-reset setting tool. This disclosure relates more particularly to methods and apparatus for providing a setting tool able to actuate subsequent plugs on subsequent downhole deployment runs, without the need to use tooling or recharges between each subsequent run. The auto-reset setting tool may include components able to recover automatically, without human manipulation, their run-in-hole position after the downhole actuation to set a plug, for example. The auto-reset setting tool may include a pressure chamber and a piston, wherein a fluid pressure can be adjusted within the pressure chamber, and wherein the piston is linked with the fluid pressure of the pressure chamber and can shift longitudinally within the auto-reset setting tool. The method using a reusable auto-reset setting tool may comprise the recovering of the position of the auto-reset setting tool after its downhole actuation.

Abstract: Method and apparatus to install a plug on a setting tool with a push-and-click mechanism. The push-and-click mechanism providing a possibility of installing a plug on a setting adapter of a setting tool, without the need to use tooling during installation, and whereby the mechanism reset itself after the deployment of the plug to provide an unset mechanism for a subsequent plug installation without the need of tooling.

The locking ring has a stopping inner surface. The plug assembly is used with one or more untethered objects, the untethered objects having an outer surface adapted to couple with the cup, and the cup having an outer surface adapted to couple with the stopping inner surface of the locking ring. The combination of cup and untethered objects is also adapted to contact an inner surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause the longitudinal movement of the cup and untethered objects while contacting the inner surface of the plug assembly until the cup contacts the stopping inner surface of the locking ring.

Abstract: A plug assembly includes a continuous expandable sealing ring having an embedded radial gap feature. The continuous expandable sealing ring includes a first section with a prominent external surface, whereby the first section with a prominent external surface includes a radial gap underneath, and a second section with a second external surface. During the setting of the plug, the first prominent external surface comes in contact with the internal surface of the tubing string, while the radial gap underneath allows avoiding transmitting radial forces from the continuous sealing ring towards the tubing string, therefore keeping the majority of the force transmission from the expandable gripping ring towards the tubing string.

Abstract: A plug assembly includes a shear landing feature, offering temporarily one or more seating surfaces for an untethered object. The shear landing feature can shear within a set plug if the force induced by a fluid pressure uphole of a landed untethered object exceeds the shear rating of the shear landing feature. A secondary fixed seating surface offers a landing and seating surface for a secondary untethered object, used typically for back-up operations.

Abstract: A plug assembly includes a retractable pivoting mechanism, offering temporarily one or more seating surfaces for an untethered object. The retractable pivoting mechanism has two or three pivoting positions, allowing the passage or the seating of an untethered object depending on the flow direction. The retractable pivoting mechanism can include a single retractable pivoting ring or multiple segments forming a ring after pivoting in their closed position. Another embodiment of the retractable pivoting mechanism includes a latching feature allowing to keep the mechanism in an opened position.

Abstract: A joint-locking plug is deployed next to tubing joint connection gap. The actuation of the joint-locking plug allows expanding a gripping portion which includes a protrusion section. The contact between the protrusion section of the gripping portion with the inner surface of the tubing string allows to end the actuation. Due to the bi-stable slips, the pumping of an actuated plug will engage the protrusion section of the gripping portion inside the joint connection gap, and provide the locking of the gripping portion of the plug. By further applying a fluid pressure, the anchoring section of the gripping portion gets engaged and further set the plug in place, allowing to perform further operation with the plug.

Abstract: A plug assembly, dedicated for ball-in-place operation, includes an expandable assembly, a locking ring, a cup and studs, to be deployed using a retrievable setting tool. The expandable assembly is adapted to be deformed radially over the locking ring and the cup, while the locking ring is retained longitudinally relative to a mandrel of the retrievable setting tool, thanks to the studs positioned within the cup. The locking ring has a stopping inner surface. The combination of the cup and an untethered object is adapted to contact an inner surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause the longitudinal movement of the cup and untethered objects while contacting the inner surface of the plug assembly until the cup contacts the stopping inner surface of the locking ring.

Abstract: A dissolvable untethered object for use inside a well fluid includes an internal cavity and a fluid entry point. The internal cavity contains a gas. The fluid entry point is closed and selectively openable so that the internal cavity can be filled with the well fluid flowing through the fluid entry point. A dissolving rate of the dissolvable untethered object is modified after contact of the well fluid inside the internal cavity with the dissolvable untethered object.

Abstract: A fluid-activated shifting tool includes a fluid entry valve, a piston, a fluid pressure chamber and a relief pressure chamber. The piston can shift and provide a force relative to the toolstring using the pressure differential created between the pressure within the fluid pressure chamber compared to the pressure within the relief pressure chamber. The fluid entry valve provides a temporary fluid entry barrier between the well fluid and the fluid pressure chamber. At a selected depth within the wellbore, the fluid entry valve can be actuated, providing well fluid hydrostatic pressure inside the fluid pressure chamber. The shifting force of the piston can be used to acuate or set a plug within a tubing string of the wellbore.

Abstract: A plug assembly includes an expandable assembly and a locking ring. The expandable assembly is adapted to be deformed radially over the locking ring. The plug assembly is used with an untethered object, which is adapted to contact an inside surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause further radial deformation of the expandable assembly, and penetration of an internal surface of the tubing string at least at one point with a gripping portion of the expandable assembly.

Abstract: A retrievable setting tool includes a collapsible expansion punch formed by sections. Each section includes an external surface that forms a portion of an expansion face of the collapsible expansion punch. Some sections are capable of sliding relative to other sections. As such, the overall shape of the expansion face may be continuous or discontinuous. The retrievable setting tool could be inside a wellbore to set an expandable member, such as a plug assembly, a patch, a liner hanger, or a packer.
