A well plug, comprising a cylindrical body, a plurality of cylindrical fins encircling the cylindrical body, a concrete core disposed within the cylindrical body and a locking feature disposed in the concrete core and configured to lock with an adjacent well plug.

Embodiments of the present disclosure include a system for installing a slip hanger assembly in a wellbore with a slip bowl comprising an aperture extending from an outer diameter of the slip bowl. The system also includes a slip coupled to the slip bowl, the slip comprising teeth on an inner face and a slot for receiving a shear pin extending through the aperture. The system further includes a running tool coupled to the slip bowl. The system includes a housing coupled to the running tool, the housing including a cylinder for receiving a reciprocating piston, the piston being movable between a first position and a second position, wherein the slip is in stored position while the piston is in the first position and an engaged position when the piston is in the second position.

Embodiments of the present disclosure include a system for suspending a hanger within a wellbore component including an actuation ring circumferentially positioned about the hanger. The system also includes an arm removably coupled to the actuation ring, the arm extending longitudinally from the actuation ring and including a head at an end opposite the actuation ring. The system further includes a landing profile formed on the head on an outer diameter of the head, the landing profile including a plurality of landing features forming a plurality of landing shoulders. The system includes a tag shoulder formed on the actuation ring, the tag shoulder arranged to contact a protrusion within the wellbore component to drive upward axial movement of the actuation ring along an axis, the upward axial movement being transferred to the arm to move the arm toward an activated position.

A self-locking packer carrier includes an integrated locking mechanism that locks the packer carrier directly to the packer cone after the sealing element is fully set. The integrated locking mechanism may include one or more compression splines extending from a packer carrier base in a radially outward direction to engage a casing after the attached sealing element has created a fluid tight seal, and a tooth profile formed along an inner diameter of the packer carrier base to lock the packer carrier to the packer cone in response to a compression force transferred to the base via the splines. The integrated locking mechanism is designed to eliminate backlash on the liner hanger system, increase vibrational resistance, accommodate liner stretch, withstand pump-out loads, and tolerate liner movement while maintaining sealing integrity.

A system that includes a wellhead. The wellhead defines a bore. A hanger system is positioned within the wellhead. The hanger system includes a piston angled relative to a longitudinal axis of the bore. A first spring biases the piston in a first direction. The piston contacts a slip segment to couple the slip segment to a casing string.

A method for sealing a wellhead assembly which is initially configured for use in performing a first operation and is subsequently configured for use in performing a second operation. The wellhead assembly in the initial configuration includes a first outer tubular member, a second outer tubular member which is mounted on the first outer tubular member, and an inner tubular member which is landed in the first outer tubular member. The wellhead assembly in the subsequent configuration includes the first outer tubular member, the inner tubular member which is landed in the first outer tubular member, and a third outer tubular member which is mounted on the first outer tubular member in place of the second outer tubular member. The method includes the steps of (a) providing a packoff assembly which includes a lower packoff that is releasably connected to an upper packoff, the lower packoff being configured to seal between the inner tubular member and the first outer tubular member and the upper packoff being configured to seal between the inner tubular member and the second outer tubular member; (b) releasably connecting an installation tool to the upper packoff; (c) using the installation tool, lowering the packoff assembly as a unit through the second outer tubular member until the lower packoff is positioned between the inner tubular member and the first outer tubular member and the upper packoff is positioned between the inner tubular member and the second outer tubular member; (d) using the installation tool, locking the lower packoff to the first outer tubular member to thereby secure the lower packoff in position between the inner tubular member and the first outer tubular member and the upper packoff in position between the inner tubular member and the second outer tubular member; (e) disconnecting the installation tool from the upper packoff; (f) after the first operation is performed, removing the second outer tubular member from the first outer tubular member; (g) removing the upper packoff from the lower packoff; and (h) mounting the third outer tubular member on the first outer tubular member. During this procedure, steps (c) and (d) are performed in a single trip, and the lower packoff remains locked in position between the inner tubular member and the first outer tubular member from step (d) through step (h).

A wellbore system includes a slip hanger arranged within a wellbore component, the slip hanger having a mechanical receptacle formed in a face of the slip hanger. The wellbore system also includes an adapter configured to couple to the slip hanger, the adapter having one or more engagement members arranged to engage the mechanical receptacle, wherein the one or more engagement members extend into the mechanical receptacle to secure the slip hanger to the adapter.

A wellhead annulus packoff and an associated method of energizing and de-energizing are disclosed. The wellhead annulus packoff includes at least one seal element, a hanger lockdown ring, a hanger lockdown energizing ring, a seal lockdown ring, a seal lockdown energizing ring, and one or more mechanical conditional operators, where the at least one seal element adapted to be energized with a first energizing force applied through a seal lockdown energizing ring and with the one or more mechanical conditional operators being engaged, where the seal lockdown ring is adapted to be energized with the first energizing force and with the one or more mechanical conditional operators being disengaged, and where the hanger lockdown ring is adapted to be energized with a second energizing force applied through a hanger lockdown energizing ring.

A system includes an annular wellhead housing and an indicator assembly. The annular wellhead housing includes a shoulder and a first passage extending radially through the wellhead housing from an exterior surface of the wellhead housing to an interior surface of the wellhead housing. The indicator assembly is configured to extend through the passage, wherein the indicator assembly, when actuated, is configured to indicate whether a hanger disposed within the wellhead housing has landed on the shoulder.

A system includes a running tool having a tool body configured to couple to a hanger assembly, a first sleeve disposed around the tool body and configured to move in an axial direction with respect to the tool body, a torque sleeve disposed around the tool body and configured to move in the axial direction as a result of movement of the first sleeve in the axial direction, where the torque sleeve has a first torque transfer interface configured to interlock with a second torque transfer interface of the hanger assembly to enable torque transfer from the running tool to the hanger assembly, and a second sleeve configured to couple to the first sleeve, where the second sleeve is configured to move to engage a lock member of the hanger assembly and to move the lock member between a locked position and an unlocked position.
