Non-aqueous viscosified carbon dioxide and method of use |
摘要 |
A method of treating a subterranean formation is provided using a treating fluid comprising from about 0% up to about 80% by volume liquid carbon dioxide. The remainder of the treating fluid comprises a viscous substantially anhydrous liquid which may be crosslinked by a metal ion source. The treating fluid is formed by the addition of polymers or copolymers of dimethylacrylamide to the substantially anhydrous fluid.
