Abstract

This paper proposes to develop a new reservoir modeling workflow extending the parallel modeling approach [Tureyen and Caers, 2005] to the GeoChron framework [Mallet, 2004]. Integrating both frameworks has several advantages and opens new perspectives for reservoir characterization, uncertainty assessment and history matching. On one hand, a GeoChron model is a flexible representation of reservoirs in which the geometry, the layering and the properties are modeled and can be altered almost independently one from each other. On the other hand, the parallel approach is closed-loop history matching method aiming at building both a static high resolution model and a coarse dynamic model consistently with each other. It achieves thus a better and easier integration of all the relevant sources of information into the reservoir model. Hence, contrary to the current modeling practice, this workflow aims at extending the type and number of perturbed parameters during history matching to the reservoir geometry, either global or internal, while producing consistent models with all the relevant information whatever their scales. However developing and implementing the proposed framework introduces new research challenges in the flow simulation, history matching and reservoir characterization domains that need to be tackled and are presented here.
