    摘要： Various embodiments disclosed related to a composition for treating a subterranean formation, and methods and systems including the same. In various embodiments, the present invention provides a method of treating a subterranean formation that can include obtaining or providing an aqueous composition including a friction-reducing water-soluble polymer including about Z1 mol % of an ethylene repeating unit including a —C(O)NHR1 group and including about N1 mol % of an ethylene repeating unit comprising a —C(O)R2 group. At each occurrence R1 can independently be a substituted or unsubstituted C5-C50 hydrocarbyl. At each occurrence R2 can independently be selected from the group consisting of —NH2 and —OR3, wherein at each occurrence R3 is independently selected from the group consisting of —R1, —H, and a counterion. The repeating units can be in block, alternate, or random configuration. The variable Z1 can be about 0.001% to about 50%, N1 can be about 50% to about 99.999%, and Z1+N1 can be about 100%. The method also includes placing the composition in a subterranean formation downhole.
