Claim Text:
1. A method of treating a hydrocarbon-bearing formation having at least one first gas permeability, the method comprising: injecting a fluid into the hydrocarbon-bearing formation, wherein the fluid comprises at least one material from at least two of Group I, Group II, or Group III, wherein: wherein the fluid at least one of solubilizes or displaces at least one of brine or condensate in the hydrocarbon-bearing formation, wherein the fluid is free of nonionic polymeric surfactant comprising perfluoroalkylsulfonamido groups, wherein any surfactant that may be present in the fluid is below its critical micelle concentration, wherein the hydrocarbon-bearing formation has at least one second gas permeability after injecting the fluid into the formation, and wherein the second gas permeability is at least 5 percent higher than the first gas permeability.
