Gas lift is an enhanced oil recovery (EOR) technique used to increase the production of crude oil from wells. It involves the injection of gas, typically natural gas, into the wellbore to lower the density of the liquid column (oil and water) in the reservoir, which reduces the hydrostatic pressure that the pump must work against. This facilitates the lifting of oil to the surface, especially in wells where natural reservoir pressure is insufficient to push the oil to the surface.
