| Abstract | Scale and corrosion control are big challenges in utilizing geothermal energy. In the production wells, during or after flashing, brineresults in higher pH, which can happen deep inside the well.Higher pH in combination with high temperature causes calcium carbonate precipitation. Silica/Silicate precipitation becomes a problem when the brine gets cold in the surface equipment and the rejection well. The paper discusses in addition to basics of scale control, new inhibitors for both silica/silicate and calcium carbonate control. |
