RESUMO

Production strategies for petroleum fields are chosen with the objective of achieving the best possible performance of the reservoir, considering physical, operational and economical constraints. In many published papers regarding production strategy optimization, only the reservoir is considered, simplifying the analysis process by not considering the operational constraints of production facilities. However, the restrictions of a production unit and the necessary equipments to guarantee the flow of petroleum not only have influence on the reservoir production and on the enterprise profits, but can also cause significant impact on the definition of the drainage strategy, influencing the number and location of producer and injector wells and the operational conditions management. In this work, two operational constraints are analyzed: the limitation of the capacity for liquid treatment and the amount of available gas for gas-lift operation. Production strategies were optimized with and without these restrictions for some case-studies and many differences were noted in the value of technical and financial indicators, such as the net present value, the production and injection of fluids and the number and location of producer and injector wells. It was possible to demonstrate the influence of operational constraints and how their exclusion from the optimization process, before definition of the number and location of wells, can lead to a wrong assessment of the field performance
