CROSSLINKABLE POLYMER COMPOSITIONS

Provided herein are crosslinkable polymer composition that comprise an aqueous fluid; a water-soluble polymer comprising carbonyl groups; an organic crosslinking agent capable of crosslMcing the water-soluble polymer comprising carbonyl groups; and a water-soluble carbonate retarder. Also provided are methods that comprise providing the crosslinkable polymer composition; introducing the crosslinlcable polymer composition into a portion of the subterranean formation; and allowing the crosslinkable polymer composition to form a crosshnked gel in the portion of the subterranean formation. Se proporciona en la presente una composicion polimerica reticulable que comprende un fluido acuoso, un polimero soluble en agua que comprende grupos carbonilo; un agente reticulante organico capaz de reticular al polimero soluble en agua que comprende grupos carbonilo; y un carbonato retardador soluble en agua. Tambien se proporcionan metodos que comprenden proporcionar la composicion polimerica reticulable, introducir la composicion polimerica reticulable en una porcion de la formacion subterranea; y permitir a la composicion polimerica reticulable formar un gel reticulado en la porcion de la formacion subterranea.
