Quick Summary

Gas lift is a method used in petroleum production to bring crude oil to the surface. It's a form of artificial lift employed when the natural pressure within an oil reservoir is insufficient to push the oil all the way up the well tubing.12

In gas lift, gas bubbles are injected into the oil. This reduces the oil's density, allowing the remaining reservoir pressure to push the lighter mixture to the surface. This gas is typically introduced down the space between the well casing and the production tubing, often through a specialized valve at the tubing's base. This technique is crucial for maintaining oil flow once natural reservoir pressure declines.2
