Abstract

The objective is twofold:

• Updating a pre-existing software tool, dedicated to mass transport simulation, within the context of the geothermal energy sector. The actual code is based on recent numerical methods (mixed and discontinuous finite elements) well suited to the modeling of highly heterogeneous matrices and complex geometry, as well as front propagation simulation.
•  The development of an inverse method for the double-media model to facilitate well test interpretation. The multi-scale description of the parameter space differentiates this model from the existing models. This approach consists of initiating the inversion process with a homogeneous medium and gradually increasing the heterogeneity. Refinement indicators of the parameter space permit to automatically manage the increase in heterogeneity.
