Gas Lift System
Journal Title: Petroleum & Petrochemical Engineering Journal - Year 2017, Vol 1, Issue 4
Abstract
Generally, a gas lift is a flexible, and a reliable artificial lift system with the ability to cover a wide range of production rates. Gas lift systems are a closed system empowered by high- pressured gas. The entire process is used to reduce the wellbore fluid pressure gradient by supplementing gas through an external source to withdraw more liquid from the reservoir under higher drawdown. Many parameters affect a gas lift system design, such as changes in the wellhead and bottomhole pressures (BHPs), produced fluid type, and productivity index of the wellbore. As these parameters change, the gas injection pressure changes. Gas lift system demands a surface compressing unit and in the well gas lifts valves (GLVs). Overall, a gas lift system is a forgiving method of enhanced production, in other words, even a poor gas lift design may increase production. To achieve a higher ramp in fluid production rate using gas lift, however, a more sophisticated design of each compartment of the system is required
