摘要: A method for fracturing a plurality of different subterranean production zones which are spaced along wellbore wherein flow is established into first or lower zone while removable sleeve blocks the other upper zones. The fractured and then notched, preforated, repositioned to establish second now blocked lower, zone. this procedure repeated until all desired have been after retrieved surface.
