During the offshore disposal of produced water, an oil sheen is sometimes visible at the surface, even when the oil content is within acceptable limits. Water-soluble organics (WSO) are known as one of the main causes of the appearance of sheen. A common approach to inhibiting sheening is the acidification of oil, in which some organic acid is added before the oil-treatment system. However, high acid volumes (3鈥�5 tons/day at 500 ppm) raise asset-integrity concerns.
