Prediction of Barium Sulfate Scale Formation in Oilfield Environment
This paper represents a simple method for predicting potential scaling tendency of barium sulfate in NaCl-water solutions over a wide range of temperature and pressure solutions. The developed method has fitted the barium sulfate literature solubility data in a mathematical equation. This equation can easily predict the BaSO4 scaling tendency in environments common to oilfield brines. Results obtained using the present model are compared with numerous experimental, calculated literature data and oilfield well cases. The present method shows good agreement with the bulk of the literature and field observation. The method presented in this study is easy to use, reliable, and can be applied to any production well where BaSO4 scale occurs.
