FOAMED HIGH VISCOSITY AQUEOUS INORGANIC ACID SOLUTIONS AND METHODS OF USING THE SAME

摘要

Foamed high viscosity aqueous inorganic acid solutions and methods of treating subterreanean well formations using such solutions are provided. The foamed acid solutions are comprised of water, at least one water soluble inorganic acid, a gelling-foaming agent comprised of a solution of a water soluble organic solvent and an ethoxylated fatty amine or a mixture of such amines and an inert gas.
