Abstract
A foam-fluid composition for use in foam fracture applications and foam slurry transport comprises a thickening amount of a viscoelastic surfactant composition, a functionally effective amount of a surfactant composition capable of forming a foam, and an aqueous liquid. Foam-fluid formulations are easily prepared, reusable, shear stable, easily pumped and form stable foams over a wide temperature range and exhibit high viscosities even at relatively high temperatures.
