Zusammenfassung:A method of treating a region of a subterranean formation adjacent a wellbore zone, the method including cooling the wellbore zone to a wellbore temperature below a temperature of the region of the subterranean formation adjacent the wellbore zone, injecting a gellable treatment composition through the wellbore zone into the region of the subterranean formation adjacent the wellbore zone, and allowing the gellable treatment composition to gel in the region to prevent or reduce flow of an unwanted fluid from the region into the wellbore zone.
