Sytems and methods for re-completing multi-zone wells

Abstract

The well includes a wellbore with a casing string that extends within the wellbore, defining a casing conduit including existing perforations. A re-completion liner extends within the casing conduit and defines a liner conduit therein, and an annular space extends between the re-completion liner and the casing string. Systems and methods include perforating the re-completion liner to create liner perforations and perforating the casing string to create re-completion perforations that are generally aligned with respective liner perforations, stimulating the subterranean formation by flowing a completing fluid through the plurality of liner perforations and re-completion perforations, controlling flow of a fluid within the annular space, and/or producing a reservoir fluid from the subterranean formation and through both the existing perforations and the re-completion perforations.
