Abstract: A well control assembly for use on subsea wells, especially during intervention or workover operations. The well control assembly is light weight, compact, and modular and, thus, can be deployed from much smaller vessels than conventional open water subsea equipment, while providing an internal diameter greater than or equal to the subsea trees upon which it would be deployed. Unlike conventional assemblies, tension and bending loads imparted by sea currents and/or a floating vessel can be resisted by the robust design of the well control assembly (and, in particular, load housing(s) thereof).

Abstract: A subsea control module for subsea well equipment has an actuator having a rod with a remote operated vehicle (ROV) interface on one end and a latch on an opposite end that latches to a subsea receptacle. Segments are releasably mounted around and to the actuator. Each of the segments has a sealed housing containing at least one internal control component. Couplings depend from the housing for engaging mating couplings in the receptacle. The housing has two radial walls, each extending along a radial line from an axis of the rod. An outer wall joins outer ends of the radial walls, the outer wall being a portion of a cylinder. An inner wall joins inner edges of the radial walls. The radial walls of adjacent ones of the segments abut each other.

Abstract: A tubing hanger to facilitate production tubing annulus access including a tubing hanger body having a central bore, a shuttle valve slidably mounted to the tubing hanger body, and at least one annulus access bore through the tubing hanger permitting fluid communication between the central bore and an annulus defined between a production tubing string and a wellbore or casing via the tubing hanger body and the shuttle valve. The shuttle valve may be slidingly movable between an open and a closed position. The tubing hanger may further include a groove enclosed by a filler, the groove providing communication between a plurality of small annulus access bores and a large annulus access bore.

Abstract: A subterranean oil or gas well apparatus is provided. The apparatus includes a single-bore production tubing hanger arranged concentric with a wellhead. The tubing hanger includes a plurality of ports and channels arranged about the tubing hanger to give operators access to the production tubing annulus and provide chemical injection capability. The ports are closable by a sliding valve. The apparatus also includes annulus and production radial-bore stab assemblies between a christmas tree and an internal crossover assembly. The stab assemblies are extendable and retractable between the chirstmas tree and the crossover assembly to allow the retrieval and installation of each independently.
