In this paper selection and field trial application of such a synergistic blend is presented to control severe scaling within produced fluid heaters...

... not be possible. This work demonstrates that through the application of discretely tagged Sulphonated Co-polymer (VS-Co) scale inhibitors, detection of residuals, from four individual wells, can be made within a single produced water. The use of tags is a field proven method to monitor the residual of VS-Co...
