(a) preparing an energized fluid comprising an aqueous medium, a gas component, a surfactant, an electrolyte, and a diutan S-8 heteropolysaccharide, and an organoamino compound selected from the group consisting of tetraethylenepentamine, triethylenetetramine, pentaethylenhexamine, triethanolamine, and any mixtures thereof, wherein the organoamino compound is incorporated in an amount from about 0.01 wt % to about 2.0 wt % based on total liquid phase weight, and preferably in an amount from about 0.05 wt % to about 1.0 wt % based on total liquid phase weight, wherein the gas component comprises carbon dioxide, and wherein the surfactant is an amine functional surfactant selected from the group consisting of zwitterionic, amphoteric, cationic and any combination thereof, incorporated in an amount of from about 0.02 wt % to about 5 wt % of total liquid phase weight, and preferably from about 0.05 wt % to about 2 wt % of total liquid phase weight;

(b) introducing the fluid into the formation through the wellbore at a pressure above the minimum in situ rock stress of the formation; and,

(c) fracturing the formation.
