Formation and Mitigation of BaSO₄ Scale in Oil Fields

Abstract:

The deposition of BaSO₄ scale is always found in the oilfield. It is difficult to be removed. Therefore, it plays a negative role to the production. The effects of temperature and water chemistry on BaSO₄ scale have been investigated by using the conductivity method in this work. An environment-friendly copolymer was prepared to control the scaling of BaSO₄. The copolymer was proved by static scale inhibition method, and weight-loss test that it has excellent scale inhibition performance and corrosion inhibition efficiency. Furthermore, FTIR spectra was used to prove that the scale inhibitor was polyepoxysuccinic acid (PESA).
