CA 2651963

A method is disclosed for performing optimal gridding in reservoir simulation, the method comprising: establishing an optimal coarse grid proxy that can replace all or parts of a fine grid with a coarse grid while preserving an accuracy of a predefined simulation model output, the step of establishing an optimal coarse grid proxy including finding, by using an optimizer, a best fit of a coarse grid output to the output of a training set.

Le procédé selon l'invention permet de réaliser un maillage optimal dans une simulation de réservoir, et comprend : la création d'un substitut à maille grossière optimal capable de remplacer tout ou partie d'une maille fine par une maille grossière en préservant la précision d'une sortie de modèle de simulation prédéfinie, la création d'un substitut à maille grossière optimal impliquant la découverte, au moyen d'un optimiseur, de la meilleure adaptation d'une sortie de maille grossière par rapport à la sortie d'un ensemble d'apprentissage.
