Patent ID: 8691731

Claim:
A method for removing deposits from a subterranean formation, hydrocarbon production equipment and/or oilfield processing equipment consists essentially of: contacting the deposit with heat from an exothermic reaction of at least one solvent and at least one acid by a procedure selected from the group consisting of: (a) in any sequence: contacting the deposit with the at least one solvent, contacting the deposit with the at least one acid; and mixing and reacting the at least one solvent and the at least one acid; and (b) contacting and reacting the at least one solvent with the at least one acid; and (c) a combination of (a) and (b); forming at least one product by exothermic reaction, and contacting the deposit with heat evolved in the exothermic reaction and/or the at least one product from the exothermic reaction; and at least partially removing the deposits by heat generated by the exothermic reaction; where the at least one solvent comprises an unsaturated compound selected from the group consisting of terpenes, terpene-derivatives, compounds having at least one carbon-carbon double bond, and combinations thereof; and where the at least one acid comprises an acid selected from the group consisting of an organic acid, an inorganic acid, and combinations thereof.
