Abstract
Gas lifting, as one of the most commonly used artificial lifting techniques, has been extensively utilized in the petroleum industry to sustain oil production rate due to its technical and economic advantages. In this study, the Two-Fluid Model has been applied in order to numerically model and simulate the production from a deviated oil well assisted with the gas lift. To achieve this, the finite difference method has been implemented to discretize and implicitly solve the system of governing partial differential equations including the conservation equations (mass and momentum). The results confirmed the applicability of the Two-Fluid model in gas lift simulation for deviated well. Furthermore, sensitivity analyses have been carried out to examine the gas lift parameters including the impact of the gas injection rate and the number of injection valves on the production performance. Obtained results indicate that oil production will be sufficiently influenced by the gas lift through rigorously optimizing the number and location of the injection valves in conjunction with the appropriate gas injection rate.
