A side-pocket mandrel is used for a gas lift system. The mandrel has two external ports, which can use external check valves when deployed downhole. Before installing the mandrel, operators preferably pressure test the interface of a gas lift valve in the pocket of the mandrel. Internal pressure testing is performed. The mandrel, however, is suited for external-pressure testing, which is impractical for other types of side-pocket mandrels. In the external pressure test, a pressure test line is coupled to the inlet port on the mandrel, which is already threaded in a reinforced area of the mandrel to receive a check valve. The other inlet port is closed off with a plug or with a check valve. When external pressure is applied with the test line, operators can determine if the gas lift valve is properly seated (i.e., whether the latch is properly engaged in the pocket). Operators can also determine if the seals between the gas lift valve and the pocket are capable of holding external pressure.
