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 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.
