Gas lift is one of the most effective artificial lift methods used in oil and gas to keep production flowing when natural reservoir energy starts to decline.Here’s how it works: • Injected gas (usually natural gas) is pumped down the annulus—the space between the tubing and casing. • That gas enters the production tubing through gas lift valves set in mandrels. • As it mixes with the produced fluids, it reduces the fluid density and column pressure, making it easier for the reservoir to push the
