Beschreibung
Zusammenfassung:	Method are provided for treating a wellbore or subterranean hydrocarbon-bearing formation to increase hydrocarbon recovery from the formation by in-depth mobility control and/or fluid diversion conformance by introducing a water soluble acrylamide polymer and a non-metallic organic crosslinking agent, or a crosslinkable acrylamide polymer, into an injection fluid entering the wellbore or the formation. Se proporciona un método para tratar un pozo o formación subterránea que tiene hidrocarburos para incrementar recuperación de hidrocarburos de la formación por control de la movilidad en profundidad y/o conformidad de desvío de fluidos al introducir un polímero de acrilamida soluble en agua y un agente reticulante orgánico no metálico, o un polímero de acrilamida reticulable, en un fluido de inyección que ingresa en el pozo o la formación.
