A novel fluid dynamic based approach for optimized gas lift operation

Integrated application of flow pattern map for long-term gas lift optimization: a case study of Well T in Indonesia

“…This study is an extension of Daton et al (2019) and Lumban Gaol et al (2019)'s study where the application of flow pattern map (FPM) is extended to be utilized in gas lift optimization. Previous studies performed by the aforementioned authors have indicated that FPM can be used in conjunction with GLP curves to verify the optimum amount of injected gas lift, shown below.…”

“…The optimum gas rates are determined from GLPC for each tubing size and reservoir pressure. Then, the superficial liquid and gas velocities (V sl and V sg ) are derived from FPM (Daton et al 2019). The economic limit liquid rate that used in this study is 10 bbl/d.…”

“…However, these flow patterns have to be mathematically and physically quantified in order to increase its utilization. The study is extended by Shoham (2006) in developing a simple graphical function to determine flow pattern region as a function of superficial liquid velocity and superficial gas velocity, named as flow pattern map (Daton et al 2019;Lumban Gaol et al 2019). Therefore, the concept of superficial liquid velocity is then introduced to the pattern mapping, shown in Fig.…”
