Abstract: A method of injecting gas into a well can include flowing the gas through a gas flow passage extending through a housing connected to a wellhead installation, the gas thereby flowing through the wellhead installation and into an annulus in the well, and maintaining fluid pressure applied to a piston of a gas injection valve while the gas flows into the annulus. A gas injection system can include a housing having a gas flow passage extending longitudinally through the housing, and being configured to connect to a wellhead installation, and a gas injection valve including a pivotably mounted flapper closure member.

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 subsea wellbore monitoring system of the present disclosure includes hanger, plug, and monitoring assemblies. The hanger assembly installs on landing in the wellhead, engages the lock profile, and has a hanger seal sealing in the wellhead. The plug assembly is supported in the hanger assembly and has a plug seal to seal in the landing. Ports of the plug assembly communicate with a bore envelope and an annulus envelope. The monitoring assembly has pressure monitors that communicate with the ports and measure pressure measurements related to the envelopes. The hanger and plug seals can be elastomeric and/or metal elements. The hanger and plug seals are preferably expandable or can be energized outward so the seals can pass any shoulders and profiles when installed in the wellbore and can then seal against the internal surfaces.
