Amide condensation products of polymeric acid and 1-aminoalkyl2-alkyl-2-imidazoline for use in compositions of oil-soluble, brine-dispersible corrosion inhibitors. Continuous or intermittent application of liquid coatings of these inhibitors on metals, particularly ferrous metals, in contact with sweet and sour petroliferous well fluids, form persistent films which afford excellent protection against corrosion, even at elevated temperature. |
