摘要
A method for testing physical integrity of production tubing (20) and production casing (16) in a gas-lift well includes the steps disposing a sealing tool (48) in the production tubing to obtain a seal at a desired location; applying a predetermined test pressure to the interior space of the production tubing; monitoring the test pressure applied for a pressure drop; and monitoring flow from the inner annular space. The physical integrity of the production casing is then tested applying pressure to the inner annular space (22); and monitoring the test pressure for a pressure drop. The sealing tool comprises a spherical member which seals against a contraction in the tubing (20). IMAGE
