Abstract:
A corrosion inhibitor composition, containing (a) a cinnamaldehyde compound, (b) an alkoxylated fatty amine, and (c) an imidazoline compound, and optionally (d) a surfactant, and (e) a solvent. A method of inhibiting corrosion of metal in contact with an acidic medium in an oil or gas field environment by introducing the corrosion inhibitor composition into the acidic medium, such as during acid stimulation operations.
