Abstract
An aqueous, foamable composition useful for formation fracturing is disclosed, which includes an ionically coupled gel system. These compositions are well suited in fracturing formation where there are insufficient or non-existent hydration units. Methods for making the compositions and methods using the foamable compositions to fracture formation with insufficient hydration units.
