Abstract

Flow and transport modeling of a deep faulted geothermal reservoir is necessary to optimize the heat exploitation. To build these models, a good understanding of the fluid flow in the faults is an important issue. To improve the knowledge of the main flow paths in a geothermal system like the one of Soultz-Sous-Forêts, we propose an approach based on the development of a hydraulic model of fault zones. The flow model is based on the identification of hydraulically efficient segments along the fault zone which are associated conceptual model. The integration of geological and structural data leads to the construction of a numerical model based on a DFN approach. It allows the evaluation of an equivalent permeability. It is a first step towards a more global reservoir model where the fault zone is assimilated to a single disk. Indeed, defining more precisely the main hydraulic and transport properties of fault zones should permit to be more consistent with the tectonic and structural history of the reservoir and thus the improvement of the reservoir modeling.
