- Procédé pour l'exploitation d'un fluide au sein d'une formation souterraine comprenant une couche traversée par un réseau de fractures et un puits.

- A partir de mesures de propriétés relatives à la couche, on caractérise le réseau de fractures par des paramètres statistiques et on construit un modèle de réseau de fractures discret. Pour chaque puits, on définit trois zones de simplification entourant le puits. A partir des paramètres statistiques, on détermine pour chaque zone un tenseur de perméabilité équivalente et un paramètre caractérisant l'orientation et la continuité verticale des fractures. Pour chaque zone, on détermine une simplification du modèle de réseau de fractures discret, en fonction de la zone, du tenseur de perméabilité équivalente et de la valeur du paramètre. A partir du modèle de réseau de fractures simplifié et d'un simulateur d'écoulement, on définit un schéma d'exploitation optimal du fluide de la formation.

- Application notamment à l'exploration et à l'exploitation pétrolière.
