Nodal Analysis of Development Wells in Gelama Merah Oil Field

This study presents a computational fluid dynamics (CFD) simulation of a multiphase system of gas–liquid flow in a vertical pipeline. The main aim of this research is to evaluate the effect of flow pattern on the influence of holdup, void fraction, and liquid film thickness for concurrent flow of air and liquid in a vertical pipe. The proposed method employs ANSYS Fluent to work on the multiphase simulation. The study shows that the accuracy of the results increases with an increase in the number of time steps and decreases in the time step size. The results of the simulation were compared with published results, and they were found to be less than 10% error. The findings of this study can be useful in understanding the behaviors of gas–liquid flows in vertical pipelines and can be applied in various engineering fields, such as chemical and petroleum industries.
