Etude de schémas multi-échelles pour la simulation de réservoir

Autor: Ouaki, Franck

En simulation de réservoir, les variations spatiales des propriétés des roches sont données par un modèle géologique défini sur une grille pouvant comporter plusieurs centaines de millions de mailles. Simuler des écoulements polyphasiques sur

Report

Filtering material properties to improve FFT-based methods for numerical homogenization

Autor: Gélébart, Lionel, Ouaki, Franck

FFT-based solvers introduced in the 1990s for the numerical homogenization of heterogeneous elastic materials have been extended to a wide range of physical properties. In parallel, alternative algorithms and modified discrete Green operators have be

International audience; Silicon carbide (SiC) is a material of interest for nuclear applications because of its stability at high temperature and under irradiation. In contrast with monolithic ceramics, architected SiC/SiC composites exhibit a quasi-

Study of multiscale methods in reservoir simulation

Autor: Ouaki, Franck

Publikováno v: Analyse numérique [math.NA]. Ecole Polytechnique X, 2013. Français

In reservoir simulation, rock properties are given by a geological model defined on a grid made of hundreds of thousands of cells. Performing polyphasic flows directly on this grid may require long computation times. Therefore, reservoir engineers us
