ABSTRACT:
The functioning of a perfluorinated compound corresponding to the formula ##STR1## wherein A.sup.- is Cl.sup.-, F.sup.- or Br.sup.-, preferably I.sup.-, to lower the surface tension of various aqueous based liquids (e.g. acids, spent acids, brines, water, etc.) and corresponding gelled liquids, when such fluids are employed in environments where they come in contact with earthen formations is improved by also incorporating into the liquid certain other water wetting surfactants.
