Zodiac Marine Services And International Chemicals Partners uses the OLI Studio (previously known as ScaleChem) software package to evaluate potential and risk of different types of scale. This software allows us to quantify the likelihood and degree of scaling problems under different pressure and temperature conditions and also allows us to determine difficulties that are likely to be encountered on seawater breakthrough or when produced water streams are redirected to alternative lines, storage tanks or separators. ScaleChem software also allows us to consider the effects of changing pH and the effect of mixed phases and changes in gas composition and GOR/GLR, allowing us to scale potential at all stages of production and transport provided that appropriate data is supplied.
ScaleChem is frequently used by us to monitor the changing conditions experienced by the assets that we currently service. Any change observed in scaling potential allows us to re-evaluate the scale inhibitors and doses that are being deployed. Most commonly, ScaleChem predictions are performed following quarterly service visits. However, when large changes are detected in scaling potential, water analyses are conducted more frequently so that we can monitor the changes
