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 Gas lift system design - PetroWiki Fundamentals of Gas For Gas Lift DesignFactors Having An Effect on The Design of A Gas Lift SystemDynamic Gas Lift Valve PerformanceReferencesNoteworthy BooksNoteworthy Papers in OnePetroExternal LinksSee AlsoOnly the gas fundamentals essential to the design and analysis of gas lift installations and operations are discussed in this section. The more important gas calculations related to gas lift wells and systems can be divided into these topics: 1. Gas pressure at depth 2. Temperature effect on the confined nitrogen-charged bellows pressure 3. An alternative solution for calculating nitrogen-charged bellows pressure at 60oF 4. Volumetric gas throughput of a choke or gas lift valve port 5.

This has the effect of reducing the hydrostatic pressure in the outlet tube vs. the hydrostatic pressure at the inlet side of the tube. Devices using this type of lift mechanism: Coffee percolators use vaporized water to lift hot water Airlift pumps uses compressed air to lift water Pulser pumps usSee more on enpedia · Text under CC-BY-SA license How Does Artificial Lift Work? | Rigzone Artificial lift is a process used on oil wells to increase pressure within the reservoir and encourage oil to the surface.
