Abstract
Scales of silica, calcite, and iron-bearing minerals have caused problems in exploiting high-temperature fluids in some geothermal fields in Iceland. Calcite scales are encountered only when the first level of boiling is within wells. Silica scales are confined mainly to waste waters discharged to the atmosphere. Iron-bearing minerals in the Krafla field wells are related to emission of volcanic gases into the geothermal system. The theory of scaling conditions and possible solutions to the problem are reviewed.
