ABSTRACT:
Subterranean reservoirs having temperatures above about 250.degree. F. are acidized by atomizing an acid precursor in an anhydrous gas to form a mist, mixing the mist with water in the borehole of a well penetrating the reservoir to form a treating fluid comprising a dispersion of fine particles of acid precursor and anhydrous gas in water, and injecting the treating fluid into the reservoir. The acid precursors are normally liquid halogenated hydrocarbons which hydrolyze in the presence of water to generate a hydrohalic acid.
