摘要: Foam fracturing fluids and methods for fracturing well formations using foam as the carrier for the propping agent are disclosed. The foams are stiff stable foams formed of a relative large amount of gas and a relative small amount of liquid. The foams are stable at surface pressures and remain stable when delivered into the well formation at the bottom of the well.
