Abstract:
Systems and methods for stimulating a plurality of zones of a subterranean formation to increase production of reservoir fluids therefrom. The subterranean formation contains a well that includes a liner that defines a liner conduit, and the systems and methods include stimulating the plurality of zones with a stimulation assembly that is present within the liner conduit without requiring removal of the stimulation assembly from the liner conduit. The stimulation assembly includes a perforation device, which is configured to selectively form one or more perforations in a plurality of portions of the liner, and a resettable sealing device, which is configured to fluidly isolate the plurality of portions of the liner from a plurality of respective downhole portions of the liner. The fluid isolation provides for selective introduction of a stimulant fluid to a selected zone of the subterranean formation that is associated with a corresponding portion of the liner.
