Abstract:
ecting the most efficient production scenario in oil fields associated with gas recycling operations is one of the major engineering concerns during the production life of a field in order to increase the cumulative oil production. So in the oil fields under gas recycling mode, variable surface parameters including separator pressure, maximum liquid rate separator capacity, well head pressure of producing wells and injection pressure of injected wells play a key role in enhancing oil production. This study designed an integrated model that included oil reservoir, production and injection wells and surface equipment systems, along with separate validations for injection and production network toachieve accurate results.Then a quadratic proxy model was constructed based upon results of twenty seven cases which were simulated through the comprehensive and dynamically integrated model. Finally, by utilizing an optimization algorithm (genetic algorithm), the optimal points of the variable parameters were obtained to maximize cumulative oil production of the wells at a specific time.The results showed that through utilizing an integrated model under optimal conditions, reservoir pressure declined gradually and this led to an increase in oil production compared to the base case (operational case).
