Case study simulation and optimization of artificial liftmethods in one of the iranian oil fields

Oil production from reservoirs usually occurs by natural flow of the fluid out of the formation. Gas lift as one of the best methods of oil recovery when reservoir pressure declines has been implemented for decades. The reservoir pressure of one of the oil fields in Iran has been dropped to a level where no natural fluid flow occurs form the reservoir. Gas lift has been proposed to compensate the natural pressure of the reservoir and ease the petroleum production from the reservoir. PIPESIM software was used to study the effectiveness of gas lift. Different parameters including tubing diameter, injected gas rates, and injection depth and their effect on inflow performance relationship (IPR) were investigated.The simulation results showed that natural energy of the reservoir is not sufficient for producing oil and gas lift as of the best methods for increasing the production rate in this field can be implemented
