Compositional model optimizes gas lift

A simulation with a compositional model, composed of a graphical front end and readily available commercial simulator software, improved the optimization of gas lift in oil wells when compared with commercial software that rely on black oil models.The basic task for finding the optimal gas injection volume requires the calculation of production rates as a function of gas injection rate.Because HYSYS1 is the only commercially available simulator designed for complete user customization; this analysis uses it in conjunction with Visual Basic programming to develop an integrated simulation environment for gas-lift optimization.Besides a rigorous thermodynamic and physical property evaluation...
