Zusammenfassung:Various embodiments disclosed related to methods, compositions, and systems for treatment of a subterranean formation. In various embodiments, the present invention provides a method of treating a subterranean formation. The method can include obtaining or providing a composition including a crosslinkable viscosifier polymer. The crosslinkable viscosifier polymer can include 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 can be independently selected from the group consisting of -H and a counterion. The composition can also include at least one crosslinker. The method also includes placing the composition in a subterranean formation downhole.
