Abstract:
A method of treating in a subterranean formation including placing a corrosion inhibitor composition into a subterranean formation, where the formation includes an acidic environment having a pH of about 5 or below, where the composition includes: an organic solvent comprising an alcohol with a flash point of at least about 75° C.; a nitrogen containing compound; an aqueous acid solution comprising HCl; and contacting a metal surface with the corrosion inhibitor composition. A corrosion inhibitor composition includes an organic solvent comprising an alcohol with a flash point of at least about 75° C.; a nitrogen containing compound; and an aqueous acid solution comprising HCl.
