Geoelectrical Survey of Blawan Ijen Geothermal Field, East Java Indonesia

Siti Diah Ayu Febriani, Rizka Daniyanti

Abstrak


An geoelectrical survey with Schlumberger configuration of Blawan Ijen geothermal field east java has been performed. This research to investigations the geothermal system based on resistivity value. In Blawan Ijen be found around 20 hot water  manifestations geothermal  field  with temperature of 510C. Measurement of primary data uses land gravitymeter G 403 type with 8 m up to 80 m spacing, made in 96 points and 5 locations in Blawan Ijen. Data obtained from this research are resistivity. The result of 2D modelling show that rock layer in Blawan Geothermal field composed of 3 rock zone with resistivity that are cap rock zone (>10 ohm meter up to 50 ohm meter), reservoir zone (>50 ohm meter up to 100 ohmmeter) and heat source zone (>100 ohm meter).
