Continuous Gas Lift Design, Diagnosis And Optimization
Continuous Gas Lift is one of the most popular methods used around the world. It is considered as an extension of natural flow. The technique consists to inject gas at the deepest point possible inside the annulus with the objective to reduce liquid density and minimize the weight of the fluid column above the formation, increasing the flow rate. Because the system have few moving parts, it is considered a reliable and safe method. Continuous gas lift is usually more efficient and less expensive for wells producing at high flow rates.
