The technology of stabilizing foamed fracturing fluids has been extended to include the use of crosslinked gels as foam stabilizers. Gasified treating fluids prepared from these gels have unique properties which differentiate them from both traditional foams and gels. Traditional foams require that the gas/volume ratio be greater than 0.52 in order to obtain a stable foam structure. Such high gas ratios produce foams with low fluid densities and low proppant concentrations. Using crosslinked gelled fluid as the stabilizer for foams, very stable dispersions of gas in liquid can be prepared with almost any gas content. Stable foams having a gas/volume ratio (GVR) greater than 0.52 as well as stable energized fluids having a GVR of less than 0.52 can be prepared. Stable energized fluids containing less gas can have appreciably higher fluid densities and proppant concentrations. This paper describes the properties of foams stabilized with crosslinked gels, their broadened uses in stimulating wells and the results of treatments.
