Gas lift - PetroWiki Continuous-Flow Gas LiftIntermittent-Flow Gas LiftApplicationsLimitations of Gas LiftNoteworthy Papers in OnePetroExternal LinksSee AlsoThe vast majority of gas lift wells are produced by continuous flow, which is very similar to natural flow. Fig. 1 shows a schematic of a gas-lift system. In continuous-flow gas lift, the formation gas is supplemented with additional high-pressure gas from an outside source. Gas is injected continuously into the production conduit at a maximum depth that depends upon the injection-gas pressure and well depth. The injection gas mixes with the produced well fluid and decreases the density and,..See more on petrowiki[PDF] Gas Lift Design and Technology - N.I.G.C Gas Lift Design And Technology Schlumberger1999 Advantages and Limitations of Gas Lift The flexibility of gas lift in terms of production rates and required depth of lift cannot be matched by other methods of artificial lift for most wells if adequate injection gas pressure and volume are available.
