Viscosifier for treatment of a subterranean formation

摘要

Various embodiments disclosed related to methods, compositions, and systems fortreating a subterranean formation including a viscosifier polymer. In various embodiments, the present invention provides a method of treating a subterranean formation that can include obtaining or providing a composition including a viscosifier polymer. The viscosifier polymer includes an ethylene repeating unit including a -C(O)NH2 Group and an ethylene repeating unit including an -S(O)2OR1 group, wherein the repeating units are in block, alternate, or random configuration. At each occurrence RI is independently selected from the Group consisting of -H and a counterion. The method can also include placing the composition in a subterranean formation downhole.
