Within the framework of the Third EC geothermal energy R and D program, which included comparative testing of geophysical methodologies over known geothermal fields, IGME applied the self potential (SP) method on the target area of Milos geothermal field in Greece. A total of 191 km of SP profiles were surveyed on the island, together with 51 km on the sea surface. Additional magnetic measurements were made of the total magnetic field, in an attempt to map some deep tectonic features of the magnetic basement. The compiled SP map correlated quite well with the spatial distribution maps of thermal gradient, fracturing and hydrothermal alteration on Milos island. SP thin sheet models (causes of SP anomalies) coincide in location with deep fracturing and high steam productivity zones of the basement.
