Abstract:
1. 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: 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.
