摘要： A tubing hanger assembly and method provide a tested and sealed tubing hanger. In one embodiment, a method for testing and sealing a tubing hanger includes attaching a test mandrel to the tubing hanger. The tubing hanger has an interior bore and a test port. The method also includes providing a test seal in the interior bore. The test seal is above the test port. In addition, the method includes adding pressure to the interior bore through the test port. The method further includes monitoring the pressure. Moreover, the method includes removing the test mandrel from the tubing hanger and attaching a production mandrel to the tubing hanger. Additionally, the method includes providing a seal in the interior bore. The seal has an upper seal and a lower seal. The upper seal is above the test port, and the lower seal is below the test port.
