Dummy valves are used to blank off communication between tubing and casing. In new installations, dummies can be retained in the mandrels until gas lift valves are required to maintain production. Then, dummies are pulled and gas lift valves and orifice valves are installed by Wireline. During the life of the well, gas lift valves installed above the fluid level can be replaced with dummies to block off injection gas or fluids. Dummy valves are also installed in the side pocket mandrel during pressure testing of tubing and casing strings.
Communication between the tubing and the casing is positively sealed off until the dummy valve is retrieved from the side pocket mandrel using standard slickline method.
