Claims
- 1. A method of retrieving a full opening subsurface safety valve from a subsurface tubing hanger in a well, including the steps of:
- elevating the well tubing at the wellhead for separating a safety joint connected with the well tubing above the safety valve to release the upper well tubing;
- elevating the upper well tubing a sufficient distance to realign a connector;
- manipulating the upper well tubing to reconnect with the portion of the well tubing below the safety joint;
- releasing a tubing holddown below the safety joint to enable retrieval of the subsurface safety valve; and
- retrieving the safety joint, holddown and subsurface safety valve with the well tubing from the subsurface tubing hanger.
- 2. The method as set forth in claim 1, including the step of:
- rotating the well tubing after releasing the tubing holddown for releasing the well tubing from the subsurface tubing hanger.
- 3. The method as set forth in claim 1, including the step of:
- increasing the pressure in the bore of the well tubing after the step of manipulating the well tubing for releasing the holddown.
- 4. The method as set forth in claim 3, further including the step of:
- pulling upwardly on the upper well tubing while increasing the pressure in the bore of the well tubing for releasing the holddown.
