Abstract
A tubing hanger is provided for suspending a tubing hanger from a wellhead housing. The tubing hanger body includes a production bore and an annulus bore, a valve opening inlet port, a valve closed inlet port, and a hydraulically operated ball valve to selectively open and close the annulus bore. An actuator sleeve surrounds the ball valve and is movable in response to fluid pressure between the open and closed positions.

A tubing hanger for suspending a tubing string from a wellhead housing, comprising:
- a tubing hanger body including a production bore, an annulus bore fluidly isolated from the production bore and in fluid communication with an annulus about the tubing string, a valve open inlet port, and a valve closed inlet port, each of the inlet ports being fluidly isolated from both the production bore and the annulus bore;
- a hydraulically actuated ball valve to selectively open and close the annulus bore;
- and
- an actuator sleeve surrounding the ball valve and connected to the ball valve, the actuator sleeve being moveable in response to fluid pressure in the valve open inlet port to move the ball valve to open, and moveable in response to fluid pressure in the valve closed inlet port to move the ball valve closed.
A wellhead assembly including a housing for landing a tubing hanger therein to support a tubing string in a well, the tubing string having a tubing bore and a tubing annulus between the tubing string and a casing, the wellhead comprising:
- a tubing hanger body including a production bore in fluid communication with the tubing bore, and a fluidly isolated annulus bore in fluid communication with the tubing annulus, a valve open inlet port, and a valve closed inlet port;
- a valve external of the tubing hanger body for controlling fluid flow in the production bore;
- a hydraulically actuated ball valve within the tubing hanger body and selectively moveable to open and close the annulus bore;
- and
- an actuator sleeve generally surrounding the ball valve and connected to the ball valve, the actuator sleeve being moveable in response to fluid pressure in the valve open inlet port to move the ball valve to the open position, and moveable in response to fluid pressure in the valve closed inlet port to move the ball valve to the closed position.
A wellhead assembly including a housing for landing a tubing hanger therein to support a tubing string in a well, the tubing string having a tubing bore and a tubing annulus between the tubing string and a casing, the wellhead comprising:
- a tubing hanger body including a production bore in fluid communication with the tubing bore, and a fluidly isolated annulus bore in fluid communication with the tubing annulus, a valve open inlet port, and a valve closed inlet port;
- a valve external of the tubing hanger body for controlling fluid flow in the production bore;
- a hydraulically actuated ball valve within the tubing hanger body and selectively moveable to open and close the annulus bore, the ball valve being moveable between opened and closed positions only in response to fluid pressure in one of the valve open inlet port and the valve closed inlet port, the ball valve being rotated between an open position and a closed position about an axis substantially stationary with respect to the tubing hanger;
- and
- an actuator sleeve generally surrounding the ball valve and connected to the ball valve, the actuator sleeve being moveable in response to fluid pressure in the valve open inlet port to move the ball valve to the open position, and moveable in response to fluid pressure in the valve closed inlet port to move the ball valve to the closed position.
