artificial lift oil and gas
Gas lift is an artificial lift technique used to increase the flow of liquids (usually crude oil) from a production well. It involves injecting compressed gas (commonly natural gas) into the wellbore to reduce the density and weight of the fluid column, making it easier for the reservoir pressure to push the oil to the surface.Gas Injection: High-pressure gas is injected down the annulus (the space between the tubing and casing).
Injection Valves: The gas enters the tubing through gas lift valves installed at various depths.
Lift Effect: The gas mixes with the liquid, lightening the fluid column and reducing hydrostatic pressure.
Production: The lighter fluid mixture flows more easily to the surface.
