A system includes a tubing hanger configured to be positioned in a wellhead assembly, the tubing hanger configured to support a tubing string, the tubing hanger including: a bore extending at least partially through the tubing hanger; and a valve disposed along the bore of the tubing hanger, wherein the valve is configured to control the flow of a fluid medium through the bore, and wherein the valve includes: an electrical actuator, wherein the electrical actuator is disposed at least partially within the tubing hanger, and wherein the electrical actuator is configured to selectively open or close the valve in response to one or more electrical signals.

Electrical actuation of a valve in a wellhead assembly

A sensor apparatus comprises a first magnetic transducer which in use is positioned on a first side of a barrier and a second magnetic transducer which in use is positioned on a second side of the barrier opposite the first side. The second transducer comprises a magnetic or electrical property which is dependent upon a sensible condition on the second side of the barrier, such as the pressure or temperature on the second side of the barrier. In operation, the first transducer generates a first magnetic field which induces the second transducer to generate a second magnetic field that is dependent upon the magnetic or electrical property of the second transducer. The first transducer detects the second magnetic field and generates a signal which is representative of the sensible condition on the second side of the barrier.

Inductively interrogated passive sensor apparatus

A subsea completion system includes a first component which comprises a first connection interface, a second component which comprises a second connection interface, and a third component which comprises a third connection interface that is complimentary to both the first and second connection interfaces. Consequently, the third component is operatively engageable with either of the first and second components.

Universal connection interface for subsea completion systems

An electrically operated actuation tool for a subsea completion system component having at least one hydraulically actuatable mechanism comprises an electric motor, a hydraulic pump which is driven by the motor and at least one hydraulic line which communicates between the hydraulic pump and a corresponding hydraulic conduit that is fluidly connected to the mechanism. In this manner, the motor drives the hydraulic pump to generate hydraulic pressure which is used to actuate the mechanism.

Electrically operated actuation tool for subsea completion system components

A method and apparatus for attaching a first component which comprises a depending portion to a second component which comprises a bore that is sized and configured to receive the depending portion, wherein the first and second components are exposed to a fluid which is at an ambient pressure, comprises the steps of inserting the depending portion at least partially into the bore and then creating a bore pressure within the bore which is less than the ambient pressure. In this manner a pressure difference between the ambient pressure and the bore pressure will force the depending portion into the bore to thereby attach the first component to the second component.

Vacuum assisted seal engagement for ROV deployed equipment

A subsea production system that is adapted to be coupled to a subsea wellhead and includes a tubing hanger adapted to be positioned in the wellhead. The tubing hanger has a flow opening extending therethrough and has at least one eccentrically located opening extending through the tubing hanger. In some cases, the tubing hanger is adapted to be not precisely oriented with respect to a fixed reference point when positioned in the wellhead. The system also includes a production tree adapted to be operatively coupled to the tubing hanger, wherein the production tree is oriented relative to the tubing hanger. In other embodiments, the tubing hanger is riot oriented with respect to the wellhead or other fixed reference point.

Subsea completion system, and methods of using same

A method for installing a subsea completion system comprises installing a conductor housing on the sea floor, landing a wellhead in the conductor housing, securing a BOP to the wellhead, landing a casing hanger in the wellhead through the BOP, connecting a tubing hanger to a THRT, landing the tubing hanger in the wellhead or the casing hanger through the BOP, installing a wireline plug in the tubing hanger production bore through the THRT, retrieving the THRT, retrieving the BOP, securing an ROSL to the christmas tree, landing the christmas tree on the wellhead, and retrieving the wireline plug from the tubing hanger production bore using the ROSL.

Apparatus and method for installation of subsea well completion systems

A lockdown device for securing a tubing hanger to a production member comprises a lockdown member which is mounted on the production member and is movable into and out of engagement with a corresponding locking profile on the tubing hanger, and an actuating mechanism for moving the lockdown member into and out of engagement with the locking profile.

A flow completion system for controlling the flow of fluid from a well bore comprises a tubing spool which includes a central bore that extends axially therethrough and a production outlet which communicates with the central bore. A tubing hanger is supported in the central bore and includes a production bore that extends axially therethrough and a production passageway that communicates between the production bore and the production outlet. A first closure member is positioned in the production bore above the production passageway, and a first metal seal is positioned concentrically between the tubing hanger and the central bore above the production passageway. In addition, a second closure member is positioned in the production bore above the first closure member, and a second metal seal is positioned concentrically between the tubing hanger and the central bore above the first seal. In this manner, the first closure member and the first seal comprise a first pressure-containing barrier between the well bore and a surrounding environment, and the second closure member and the second seal comprise a second pressure-containing barrier between the well bore and the environment.

A flow completion apparatus comprises a wellhead housing installed at an upper end of a well bore and a tubing spool connected over the wellhead housing. The tubing spool includes a central bore extending axially therethrough, a production outlet communicating with the central bore and an annulus passageway communicating with the tubing annulus. A tubing hanger is supported in the central bore and includes a production bore extending axially therethrough and a production passageway communicating between the production bore and the production outlet. The tubing spool comprises a workover passageway extending between the annulus passageway and a portion of the central bore located below the top of the tubing hanger. Furthermore, the tubing hanger comprises an annulus bore extending between the workover passageway and the top of the tubing hanger.

A tubing spool has an internal landing profile for a reduced diameter tubing hanger which is arranged and dimensioned to pass through the bore of a slimbore marine riser and BOP of a subsea completion system. The tubing spool is arranged and designed for securement to a wellhead at the sea floor. The tubing hanger is arranged and designed to be sealingly positioned in the tubing spool landing profile and has a production bore and a relatively large multiplicity of electrical and hydraulic passages which terminate at a top end of the hanger with vertically extending electrical and hydraulic couplers. A passage is provided, independent of the tubing hanger, which provides communication from above the tubing hanger to the well annulus below the hanger. The tubing spool may have a slim bore BOP or a conventional xmas tree attached at its top end.
