| Abstract | Based on the definition of geothermal requirement, that is, the combination of resistivity's of an altered formation and a fracture type geothermal reservoir and a depth of their interface from the surface, a drilling target for geothermal development at Onikobe was determined by the interpreted result of resistivity sounding curves together with seismic reflection data of lacking reflectors. And this was proved by the exploratory well, U-1. |
