Patent ID: 7494957

Claim:
A subterranean formation treatment fluid comprising an aqueous medium, a gas component, a surfactant, an electrolyte, an organoamino compound, and a gas phase stabilizing heteropolysaccharide having a tetrasaccharide repeating unit in the polymer backbone as represented by the chemical formula: wherein three different saccharides are present in the repeating unit, the three different saccharides including D-glucose, D-glucuronic acid, and either L-rhamnose or L-mannose; M + is an ionic species; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , and R 10 are selected from the group consisting of hydrogen, methyl, acetyl, glyceryl, or a saccharide group containing one to three saccharides units; R 11 is a methyl or methylol group; and the weight average molecular weight (Mw) for the heteropolysaccharide is from about 10 5 to about 10 7 ; wherein the heteropolysaccharide is selected from the group consisting of gellan gum and gellan gum derivatives, diutan gum and diutan gum derivatives, rhamsan gum and rhamsan gum derivatives, polysaccharide S-88 and polysaccharide S-88 derivatives, polysaccharide S-198 and polysaccharide S-198 derivatives, polysaccharideNW11 and polysaccharide NW11 derivatives, and any mixtures thereof wherein the gas component comprises from about 10% to about 90% of total fluid volume percent; wherein the fluid is a stable energized fluid at temperatures of 121° C. and above; 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 wherein the organoamino compound is selected from the group consisting of tetraethylenepentamine, triethylenetetramine, pentaethylenehexamine, triethanolamine, and any mixtures thereof, and 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.
