摘要
A method for testing physical integrity of production tubing and production casing in a gas-lift well includes the steps of opening communication from a pressure source to an interior space of the production tubing; disposing a sealing tool in the production tubing to obtain a seal at a desired location of the production tubing; opening communication from an inner annular space of the well; 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 by opening communication from a pressure source to the inner annular space; closing communication from the interior space of the production tubing; applying a predetermined test pressure to the inner annular space; and monitoring the test pressure for a pressure drop.
