Basic Components of Gas Lift valve

Port

Type of Gas Lift Valve

Gas Lift Valves

Dummy Valve

Installed in SPM as a non-equalizing isolation toolTo blank off the tubing for production until gas lift valves are requiredTo remove dummy valve, we used standard wireline retrieval method

Injection Pressure Operated Valve

Dome is charged to a specified pressure by using NitrogenThe bellow serves as a flexible or responsive elementNot using spring, depend on the pressure in the domeBuildup of injection pressure open the port, a reduction in injection pressure close it

Production Pressure Operated Valve

The port is exposed to the injection pressureThe bellow is exposed to the production pressureDouble element valveThe dome of this valve maybe charged or not charged by nitrogen. Depends on the condition

Pilot Valve

Normally used to kick-off or unload the well (intermittent)It has both small port to control the spread and large port to ensure efficient gas flow
