Acidizing compositions including ampholyte polymers
Various embodiments disclosed relate to acidizing compositions including an ampholyte polymer. Various embodiments provide a method of treating a subterranean formation. The method can include placing in a subterranean formation an ampholyte polymer including an ethylene repeating unit including a —C(O)NH2 group, an ethylene repeating unit including an —S(O)2OR1 group, and an ethylene repeating unit including an —N+R23X− group. At each occurrence, R1 can be independently selected from the group consisting of —H and a counterion. At each occurrence, R2 can be independently substituted or unsubstituted (C1-C20)hydrocarbyl. At each occurrence, X− can be independently a counterion.
