<p>A composition is provided which, when applied to a metal surface, forms a corrosion-inhibiting film thereon. The composition comprises the reaction product of a first component selected from an epoxy resin, an epoxidized alkene and a substrate having at least one displaceable halogen, and a second component comprising a monomercaptan in a hydrocarbon diluent. The composition is applied by contacting the metal surface with the composition. The composition is particularly useful in the treatment of down- well metal surfaces in oil and gas wells to inhibit the corrosion of the metal under highly corrosive conditions, and is effective even in the presence of polymeric permeability control agents such as aqueous polyacrylamides.</p> |
