Abstract
Jaboi is located in Weh Island at the northern tip of Sumatra. The existence of geothermal activities in Jaboi is a part of other geothermal activities along the Semangko geological depression in Sumatra. Geothermal manifestations situated in the Quaternary lava (1.1 ± 0.1 Ma) rocks environment. These manifestations are solfatara, fumaroles, hot ground, mud poll and hydrothermal alteration with the temperature between 98..C and 106..C. Hot water temperatures in this area ranging from 95..C to 96.4..C. Integrated geo-scientific data from Jaboi indicated that the prospect area of this geothermal field ± 6 km2 which controlled by fault systems. Geophysical and geochemical surveys delineated top reservoir at 600 meter below sea level with estimated temperature of 255°C. At least 50 MWe of possible reserve is calculated in the study area.
