Abstract
The present invention relates to a method of acidizing a subterranean formation or well bore employing an acidic solution containing a stabilized corrosion inhibitor composition comprising an inhibiting effective amount of an acetylenic alcohol, a quaternary ammonium compound, an aromatic hydrocarbon, an antimony compound, and a stabilizer which substantially prevents precipitation of solubilized antimony-containing compounds from aqueous solutions.
