Chelating agents used in conjunction with stimulation operations in a subterranean formation can often be limited by the pH range over which they may effectively complex metal ions. Perfluorinated chelating agents may have a broader effective pH range for metal ion complexation than do other types of chelating agents, particularly at highly acidic pH values. Methods for treating a subterranean formation can comprise: providing a treatment fluid comprising a perfluorinated chelating agent having at least two carboxylic acid groups; introducing the treatment fluid into a subterranean formation; and complexing metal ions in the subterranean formation with the perfluorinated chelating agent.
