  • Patent number: 10872182
    Abstract: The present invention relates to a method for optimizing a fluid deposit traversed by a fracture network. For this method, the deposit is discretized in a meshed representation, a “dual medium” approach is used, and the exchange flows are determined between the meshes, together with corrective factors. The corrective factors are dependent on the initial pressure and the minimum production pressure of the deposit. The fluid flows in the deposit are simulated by means of these flows and these corrective factors.
