Title: Carbon dioxide and polymer compositions for permeability control and sealing

Abstract

A method of treating a material to achieve at least one of reducing surface wettability of the material or reducing fluid transport through the material includes exposing the material to a composition including a solution of a polymer portion and carbon dioxide for a period of time. The polymer portion includes at least one of a polyfluoroacrylate or a copolymer of a fluoroacrylate and a comonomer. A pressure of the composition is maintained above the cloud point of the polymer portion at a concentration thereof in the carbon dioxide for the period of time.
