ABSTRACT:
A corrosion-inhibiting composition of matter comprising (1) the reaction mass resulting from the reaction of an .alpha.,.beta.-unsaturated hydrocarbyl nitrile and a metal hydrocarbyl sulfonate, (2) an alcohol, (3) a hydrocarbon diluent, and optionally (4) an epoxy resin. The composition is particularly useful in the treatment of downhole metal surfaces in oil and gas wells for inhibiting the corrosion of the metal.
