Abstract
A method of inhibiting corrosion of iron and steel alloys in contact with oil-in-brine emulsions is claimed. The method comprises treating the oil-in-brine emulsions with an effective amount of a water soluble polymer having an average molecular weight of at least one million and an effective amount of a nitrogen-containing corrosion inhibitor.
