Hydrothermal alteration and the evolution of the Lahendong geothermal system, North Sulawesi, Indonesia
The Lahendong geothermal system (North Sulawesi) is the first geothermal system in eastern Indonesia developed for electricity generation. It is a liquid-dominated system located in steep terrain with thermal manifestation at about 750 m asl. To date the system is penetrated by 27 wells to measur...

The Lahendong geothermal system (North Sulawesi) is the first geothermal system in eastern Indonesia developed for electricity generation. It is a liquid-dominated system located in steep terrain with thermal manifestation at about 750 m asl. To date the system is penetrated by 27 wells to measured depths ranging from 1500 to 2500 m. The reservoir rocks are andesite and rhyolite ranging from to 2.2 to 0.5 Ma. The typical temperature inside the thermally active area is 250 oC at about 1000 m bsl.
