Various embodiments disclosed related to methods, compositions, and systems for treating 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 R1 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. |
