| Abstract | The Las Pailas Geothermal Field (LPGF) is the second geothermal development in Costa Rica (Las Pailas Unit 1). The Geothermal Resources Service Center (GRSC) of the Costa Rican Electricity Company (ICE) is drilling deep directional wells in the eastern sector of LPGF, where Unit 2 will be installed. An integral analysis of lithostratigraphic and mineralogic data obtained from the wells drilled for Unit 1 (western sector) and for Unit 2 (eastern sector) shows that there is a geothermal reservoir similar to the one found for Pailas I. The limits of this reservoir are still unknown and the possible connection with Pailas 1 has still not been confirmed. The geologic model presented in this paper reveals recently obtained geological information in this sector of the field. |
