Abstract

Métodos para usar polímeros hidrosolubles con modificacion hidrofoba para tratar intervalos de una formacion subterránea con permeabilidades variables. Una realizacion ilustrativa presenta un método para el tratamiento de un intervalo de una formacion subterránea cuya permeabilidad varía. El método comprende poner en contacto al intervalo con un polímero hidrosoluble con modificacion hidrofoba con capacidad para reducir selectivamente la permeabilidad al agua efectiva del intervalo sin una reduccion comparable de la permeabilidad efectiva del intervalo a los hidrocarburos. El polímero con modificacion hidrofoba modifica el intervalo para otorgarle una permeabilidad más uniforme sin impedir sustancialmente el flujo de fluidos a través del intervalo. El método comprende además introducir un fluido de tratamiento en el intervalo. La permeabilidad más uniforme del intervalo da lugar a un tratamiento del intervalo por el fluido de tratamiento más uniforme de lo que sería posible sin el tratamiento del intervalo con el polímero con modificacion hidrofoba.
