Abstract
A downhole system and method is disclosed for sealing a previously perforated section of casing and refracturing the subterranean formation in a region of the subterranean formation remote from those regions previously fractured. The system includes a truss structure radially expandable between a contracted configuration and an expanded configuration and a sealing structure disposed radially external to the truss structure. The truss structure and the sealing structure are set in their expanded configurations so that the sealing structure is put into engagement with the perforated section of casing so as to restrict the flow of fluids from the perforated section of production tubing into the subterranean formation.
