Abstract: A wellbore tool includes a wellhead to be installed at an entrance to a wellbore formed through a subterranean zone. The wellhead includes an uphole wellhead end that can extend upward from the entrance, and a downhole wellhead end that can extend downhole into the wellhead. The wellhead defines an opening extending from the uphole wellhead end to the downhole wellhead end. A spacer tool is attached to the downhole wellhead end, and includes an uphole spacer tool end and a downhole spacer tool end. The spacer tool defines a tapered opening tapering from end to end. The tool includes a master valve attached to the downhole spacer tool end of the spacer tool. The master valve defines a flow pathway fluidically coupled to the opening defined by the wellhead and the tapered opening defined by the spacer tool.

Abstract: A wellhead housing of a wellhead assembly can include a body having a top end, a bottom end, and a cavity that traverses its length between the top end and the bottom end. The wellhead housing can also include a main channel that traverses the body from the cavity at a distal end of the main channel to an outer perimeter of the body at a proximal end of the main channel, where the proximal end of the main channel is located closer to the top end of the body compared to the distal end of the main channel, and where the distal end of the main channel is located closer to the bottom end of the body compared to the proximal end of the main channel.

Abstract: A tubing hanger assembly includes a tubing hanger body, a downward facing load shoulder which is axially displaceable relative to the body, and first and second inclined surfaces which are configured to engage each other. One of the first and second inclined surfaces has a fixed axial position relative to the body and the other of the first and second inclined surfaces has a fixed axial position relative to the load shoulder. The first and second inclined surfaces are configured such that rotation of one of the first and second inclined surfaces relative to the other of the first and second inclined surfaces results in axial displacement of the load shoulder relative to the body.

Abstract: An improved wellhead electrical connection assembly utilizing upper and lower retention mechanisms to minimize pressure and fluid leakage in the event of a tubing part or other failure. The upper retention mechanism ensures the connection assembly remains within a tubing hanger. The lower retention mechanism provides a secure connection to a downhole cable that can breakaway without damaging or dislodging other components of the assembly during an emergency event.

Abstract: The dual string hanger assembly includes an insert and an adaptor. The insert is installed within the inner diameter of the tubing head and the adaptor is coupled over the top of the tubing head. The insert therefore becomes sealed within the interior space between the tubing head and the adaptor. In use, the production string is supported in a tubing hanger profile built into the adaptor above the existing tubing head. The auxiliary line is supported in a second, smaller diameter hanger profile that is on the insert, which is installed within the tubing head. The assembly may include a hanging apparatus, such as slips, to secure the auxiliary line in the hanger profile of the insert.

Abstract: A tubing hanger assembly may include a tubing hanger and an annulus plenum designed for annulus flow that allows for communication of otherwise discontinuous bores and/or flow paths above and below the annular plenum. An annulus plenum flow path arrangement is used to connect discontinuous annulus bores from the top and the bottom of the tubing hanger in a way that maximizes flow through area while leaving space in the tubing hanger for other through bores. Further, a specifically designed flange may reduce the size and quantity of fasteners and be used in areas where radial space does not permit a full flange. The flange is compact and designed to maximize the size of an equipment-loaded bore that needs an end connection while doing so in a space-constrained environment.

Abstract: A running tool (87) having an annulus seal assembly (86) and casing hanger (89) attached thereto may be sent into to the wellhead (1) to lock and preload the casing hanger (89) in a single trip. The running tool (87) may be rotated a first time to drop the annulus seal assembly on the casing hanger (89), a first pressure may be applied axially above the annulus seal assembly to set the annulus seal assembly, the running tool may be rotated a second time to close a gap between the annulus seal assembly and the wellhead, and a second pressure may be applied axially above the annulus seal assembly to preload the casing hanger.

Abstract: A well system includes a wellbore, a conductor extended within the wellbore, and a wellhead installation arranged at an opening to the wellbore. The wellhead installation includes a low-pressure surface wellhead housing (LPWH) having opposing upper and lower ends, an extension joint secured to the lower end at an offsite location prior to delivery to the wellbore, an extended casing head housing (ECHH) providing a body having opposing first and second ends and sized to be received within the LPWH, the second end being secured to an uphole end of surface casing at an offsite location prior to delivery to the wellbore, and one or more annulus valves extending through a sidewall of the LPWH to provide fluid communication with a conductor-casing annulus defined between the conductor and the surface casing when the ECHH is received within the LPWH.

Abstract: A method for aligning a tree within a resource extraction system includes disposing a riser system on a wellhead of the resource extraction system without utilizing a mechanical alignment system to circumferentially align the riser system with the wellhead. The method also includes disposing a tubing hanger at a landed position within the wellhead. In addition, the method includes disposing an orientation mechanism on the wellhead. The orientation mechanism includes an alignment feature configured to engage a corresponding alignment feature of the tree. Furthermore, the method includes moving the tree toward the wellhead such that the alignment feature of the tree engages the alignment feature of the orientation mechanism to approximately establish a target circumferential orientation of the tree relative to the tubing hanger.
