Compositions and methods for treating subterranean formations

Abstract

A solution containing a compound having the general formula XF.nH2O2, wherein X is K+, Na+ or NH4+ and n is an integer from 1 to 3 (e.g., a peroxysolvate of potassium fluoride compound such as potassium fluoride hydroperoxide (KF.H2O2)) is injected into a subterranean formation in order to increase its permeability, especially with respect to hydrocarbon flow. These compounds serve to dissolve a wide variety of subterranean formation minerals (e.g., siliceous materials as well as carbonaceous materials). Potassium hydrofluoride (KHF2), can be employed with these compounds to produce particularly efficacious subterranean formation treatment solutions.
