Scale inhibitors will solve calcium carbonate deposit problems, but not aeration problems. Aeration of produced water and consequent iron oxide precipitation in the oil field is a common mechanical failing that can lead to serious loss of injectivity and even complete loss of injection wells being used for disposal or water flooding. Redox potential has been successfully measured in the field and, in one case, has correlated well with suspended iron oxide and oxygen concentration measurements.
