Modelos Proxy, alternativa para reducir los tiempos de cómputo durante la simulación numérica

Abstract

The reservoir simulation is a tool which had been evolving at the same time than the petroleum industry; its main purpose is to predict the behavior of a reservoir and afterward finding the optimum scenario in order to increase the oil recovery. However, numerical simulation studies could be very expensive because factors such as grid size and detail of the study to develop (It is associated to long computational and analysis times). Furthermore the time it would take to evaluate multiple possible scenarios to define the best exploration strategy. For this reason, field engineers use statistical tools during numerical simulation studies oriented to history match, sensitivity analysis, uncertainty analysis, optimization and forecasting. One of these statistical tools is the Proxy model, it appears as an alternative to reduce computational times which does not need a high accuracy grade in the results. This article looks for a reader contextualization about the meaning of Proxy model and its value during reservoir simulation studies, and also to present an application study.
