Abstract of the Disclosure It is known to treat subterranian formations with aqueous composi- tions. It is desired to reduce the surface tension of such aqueous composi- tions. The present invention provides a novel composition having a reduced surface tension. The present invention provides an aqueous composition suit- able for use in treating subterranean formations comprising A. an aqueous liquid; and dispersed in said aqueous liquid, B. an effective amount of a perfluorinated surfactant of the formula Image A- wherein A- is Cl- , F- , I- or B--; C. a second surfactant blend comprising about the following percentages by weight, 57 percent polyethylene glycol monostearate; 19.2 percent sodium di(2-ethylhexyl)sulfosuccinate; 3.0 percent di-2-ethylhexyl maleate; 10.1 percent isooctyl alcohol; 4.5 percent isopropyl alcohol and 6.2 percent water; and D. a third surfactant selected from the group consisting of an adduct of a C10-C12 alcohol with five moles of ethylene oxide, an adduct of trimethyl-1-heptanol with seven moles of ethylene oxide, and mixtures thereof; the total amount of said perfluorinated compound and other surfactants being present in said aqueous liquid in an amount ranging from 0.02 to 0.2 percent by weight of said composition.
