Estratégias de produção através do Indicador de Potencial de Produtividade

Abstract

Oil reservoir management is a very complex task in the field of reservoir engineering. The physical parameters, economic constraints and operational conditions directly interfere in the process of defining the best production strategies. In view of this difficulty, this paper proposes a methodology to define a best strategy that identifies wells with higher production in points of maximum proximity, in Hydraulic Flow Units (HFUs), through the Productivity Potential Indicator (PPI) associated with the reservoir Productivity Map, in order to estimate the optimal location for the adequate positioning of wells and avoid exhaustive simulations, being an efficient strategy for the development of an oil field. The case study is based on the UNISIM-I-D synthetic reservoir model of an offshore oil field, with characteristics similar to the Namorado Field, located in the Campos Basin, Brazil. The results obtained were presented from the prediction of accumulated oil production through IPP, without and with the help of the Productivity Map, from cases performed in the Computer Modelling Group Ltd (CMG) suite. In the cases analyzed within the Productivity Map, the lowest IPP indicated the highest accumulated oil production, thus indicating the largest producing well among the wells analyzed in the reservoir.
