decades in order to increase production in oil fields. Despite that there are
still lacks of user friendly software in gas lift optimization. The ultimate
goal of this study is to develop user friendly program using commercial Computational
Fluid Dynamics (CFD) software for optimization of continuous flow gas lift for
single well. GAMBIT 2.3.16 was used for modelling the tubing string prior the
simulation process. Two-phase CFD calculations using Eulerian–Eulerian
model and commercial CFD package FLUENT 6.0 were employed to calculate the gas-liquid
flow in the string. The depth and the rate of gas injection were the main parameter
tested. The simulation results showed that the highest velocity of flowing fluid
was observed when the gas was injected at the lowest point, which is at 5 m
from the casing shoe in this study. The velocity of flowing fluid was increased
by 1.7% when the gas injection rate increased 20%. This interrelationship was
observed with regard of the decrease in liquid column density. CFD is capable
in aiding faster continuous flow gas lift optimization process.]]>Ayatollahi, S., M. Narimani and M. Moshfeghian,2004Aamo, O.M., G.O. Eikrem, H.B. Siahaan and B.A. Foss,2005Alarcon, G.A., C.F.
