Artificial gas lift is one of the most important operations to improve extraction from oil wells with low or no production. In the gas lift method, the gas injection rate has an optimal value, and increasing or decreasing its amount will reduce the oil production. This optimal point changes during production and creates an optimal path. Also, the allocation of gas in one time step changes the production of different wells and also reduces the reservoir pressure. This can affect the optimal gas allocation of the next time step. In the past, much research has been carried out in the field of gas lift optimization, but most of them have not used the powerful tool in a dynamic model to find a good optimal path. In this article, first IPM software was used to simulate the field. The fluid, tank, well, and well equipment were simulated with PVTP, Mbal, Prosper, and Gap software, respectively. All parts were then combined with Gap software to create a unified system. Finally, Gap optimization was used to find the optimal gas rate path of the wells in artificial lift. The results showed that the use of integrated system optimization with less available gas limitation has an optimal point with higher production. The reason for this is considering the dynamic model and the effect of reservoir pressure on the gas injection rate for optimization by the integrated system.
