Thermodynamic Cycle of the Maibarara Geothermal Field, Philippines

Abstract

The Maibarara Geothermal Field has been in commercial operation since February 2014 commencing with 20-MW generation. In April 2018, an additional 12-MW facility was completed providing total installed capacity of 32 MW for the field. The thermodynamic cycle of the geothermal field including its energy facilities was analyzed using pressure-enthalpy diagram. Geochemical data and tracer flow testing results were the references used for thermodynamic analysis. The thermodynamic cycle provides a better understanding and holistic view of how the Maibarara production system works, especially on fluid transport from the reservoir to surface facilities.
