A wellhead port plug assembly includes a first plug body including connection elements allowing the first plug body to be sealingly and removably mounted in a port of a wellhead of a hydrocarbon well. The plug assembly includes a spool unit displaying an axial through-channel extending between a first end and a second end of the spool unit, which spool unit includes a first flange section arranged at the first end for sealingly mounting the spool unit to the wellhead aligning the through-channel with the port, and a second flange section arranged at the second end; a second plug body including connection elements allowing the second plug body to be sealingly and removably mounted in the through-channel; and a blind flange which is sealingly and removably mounted to the second flange section allowing the second plug body and the first plug body to be removed from the wellhead via the through-channel.

Present invention regards a device for injection and stimulation of fluids in a wellbore, where the device is typically is installed in Christmas trees, wellheads or subsea. The device comprises two separable sections, where the section that is mounted/arranged within the Christmas tree or wellhead, will remain in a closed position even if the other section due to external forces is broken off or in other ways is damaged.

Various valves for regulating flow are provided. In one embodiment, a valve includes a hollow body with an inlet and an outlet and a trim disposed inside the hollow body. The trim includes a control component that can be moved to regulate flow from the inlet to the outlet. An actuator is coupled to the trim and enables both linear movement of the control component and rotational movement of the control component within the hollow body during operation of the valve. Additional systems, devices, and methods are also disclosed.

The present disclosure relates to a wellhead assembly 10 having a gas flow control valve 14 with a tubular inlet 24 into which a fluid from a well tube flows, and a gas flow line 16 through which the fluid flows out from the gas flow control valve. An inlet tube 12 has a first end operably coupled to the well tube, and a second end 26 coupled to the inlet 24 of the valve. The inlet has a first groove 30 formed on a surface thereof, and the inlet tube has a second groove 34 formed on a surface thereof. A split lock ring 28 is used which partially rests in, and which is substantially fully compressed into, one of the grooves, when the inlet tube is telescopically coupled to the inlet. The lock ring engages with the other one of the grooves as the two grooves become axially aligned during coupling, to lock the inlet tube to the inlet while permitting rotational movement of the inlet tube relative to the inlet.

A system includes a choke valve having a fluid inlet configured to receive a fluid at a first pressure and a fluid outlet configured to output the fluid at a second pressure. The choke valve also includes a fixed component and a movable component defining a throttling orifice between the fluid inlet and the fluid outlet. Additionally, the movable component is configured to automatically move relative to the fixed component in response to a change in the first pressure to maintain a consistent percent pressure drop between the first pressure at the fluid inlet and the second pressure at the fluid outlet.

An autonomously operated well intervention tool system includes a lubricator sealingly affixable to an upper end of a well. The lubricator has a latch at an upper end thereof. A well intervention tool system is releasably matable with the latch. The well intervention tool system comprises a wellbore intervention device at a longitudinal end thereof. The lubricator has at least one isolation valve to close fluid communication between the well and the lubricator.

A landing string includes a valve having a valve member mounted within a flow path extending through the landing string, and a valve control system for use in operating the valve to move the valve member between open and closed positions to control flow along the flow path. The valve control system is reconfigurable between a first configuration in which the valve is operated or controlled under a fail-as-is (FAI) mode of operation, and a second configuration in which the valve is operated or controlled under a fail-close (FC) mode of operation.

An apparatus for assisting an actuator to close a valve has a cylindrical booster housing with a central axis. The booster housing includes an upward facing piston cavity and a downward facing lower cavity with internal threads for selectively coupling with external threads of a piston head of a valve actuator. A bulkhead is formed between the piston cavity and the lower cavity. The bulkhead has an opening for selectively accepting an actuator stem of the valve actuator therethrough. A booster piston is located within the piston cavity. The booster piston has a piston mounting means located on its bottom side for selectively securing a top end of the actuator stem of the valve actuator to the booster piston. The booster piston is moveable upwards in an axial direction to move the valve from a lower open position to an upper closed position.
