    Abstract: Formation treatment compositions may include a surfactant and an aqueous acid solution or mixture. The surfactant may include one or more of C6-C20-fluoroalkylsulfonate, C6-C20-alkylarylsulfonate, C6-C20-alkylcycloalkylsulfonate, C6-C20-arylsulfate, C6-C20-alkylphosphonate, C6-C20-arylphosphonate, C6-C20-alkylpolyetherphosphate, C6-C20-alkylpolyetherphosphonate, C6-C20-alkylcarboxylate, C6-C20-arylcarboxylate, and polyoxyethyleneamine. In the formation treatment compositions, the surfactant may be configured to partially or fully adsorb on a carbonate formation to accelerate the partial dissolution of the formation. Methods of treating a formation may include introducing the formation treatment composition into a wellbore such that that the formation treatment composition contacts the formation.
