RESUMO

The selection of production strategies for petroleum field development is an important task. The specific case in which there are constrained surface facilities, the allocation of production and injection well rates is one more item to be optimized. When the problem involves several segregated reservoir units, each of which characterized by its own geological model, the simulations should not be considered as isolated because they are effectively coupled by the limits of the total flow of production and injection. In this scenario of multiple reservoirs, this work proposes the study of production rates allocation using traditional approaches and also applying the simplified Integrated Production Modeling (IPM), considering a fixed position for the wells. The simplified IPM consists of using an application that manages an explicit coupling between reservoir simulators and production systems, the latter element represented in a simplified form. In this work, the total gas rate was selected as the surface constraint in two case studies. The traditional procedures of segregated simulation with manual optimization and amalgamating the simulation models into a single model are used, besides the simplified IPM. In each approach, three methods are applied for well rates allocation, available in the adopted commercial simulator and implemented in the specific routine (RAV). The obtained results show that the use of different flow allocation algorithms can lead to changes in estimated NPV above 12% and indicate that the simplified IPM is valid and it can be considered the best alternative in some specific scenarios.
