Calcium Carbonate Deposition in Geothermal Wellbores Miravalles Geothermal Field Costa Rica
Abstract/Contents
- Abstract
- Calcium carbonate deposition takes place in the wells of the Miravalles geothermal field in Costa Rica. Data from three long term flow test periods performed in well PGM-1 are analyzed through different methods, especially for the third and longest period which took place after mechanical scale removal had been performed. For this test a collection of chemical and thermodynamic data is used to investigate the evolution of the well production with time. Hotter fluids are suspected to enter the well at the end of the test, counting for higher enthalpy values and decrease in scale deposition rate. Remedial actions are suggested to reduce the scale deposition rate, or to remove the deposits formed, taken from the experience gained in different geothermal fields in the world, dealing with the same problem.
