Patent ID: 8541347

Claim:
A method comprising: placing an acid-internal hydrocarbon-acid emulsion composition in a subterranean formation wherein the hydrocarbon-acid emulsion composition comprises: an acid phase, wherein the acid in the acid phase comprises an acid generating compound selected from the group consisting of ortho ester, poly(ortho ester), poly(hydroxybutyrate), poly(anhydride), aliphatic polycarbonate, poly(amino acid), poly(ethylene oxide), polyphosphazene, and a combination thereof; a hydrocarbon blend phase in an amount in the range of from about 50% to about 95% by volume of the hydrocarbon-acid emulsion, wherein the hydrocarbon blend phase comprises at least about 65% hydrocarbons having from six carbons (C 6 ) through eleven carbons (C 11 ); and, an emulsifying agent, wherein the hydrocarbon-acid emulsion does not comprise a viscosity reducing agent.
