In a system and method of fracturing a subterranean formation, fluid for perforating is received in a downhole tool through a tubing string, the downhole tool residing in a wellbore. A wall of the wellbore is perforated proximate the downhole tool. A fluid for fracturing is received in the downhole tool through the tubing string. The subterranean formation proximate the downhole tool is fractured. The operations of receiving a fluid for perforating, perforating, receiving a fluid for fracturing, and fracturing are performed while keeping at least a portion of the downhole tool in the wellbore.
L'invention porte sur un système et un procédé qui permettent de fracturer une formation sous-terraine, procédé selon lequel on distribue un fluide de perforation à un outil fond de trou à travers une colonne de production, l'outil fond de trou résidant dans un puits de forage, et une paroi du puits de forage étant perforée à proximité de l'outil fond de trou. On distribue un fluide de fracturation à l'outil fond de trou à travers la colonne de production. On fracture la formation sous-terraine à proximité de l'outil fond de trou. On effectue les opérations de distribution de fluide de perforation, perforation, distribution de fluide de fracturation, fracturation tout en maintenant au moins une partie de l'outil fond de trou à l'intérieur du puits de forage.
