ABSTRACT:
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.
