Abstract
Self-potential (SP) method is applied for monitoring of both liquid dominated and steam dominated geothermal systems. Practical procedures of SP monitoring data analyses are discussed with simulation results and field data from Mori liquid dominated geothermal system. As a preliminary study for a steam dominated system, repeat SP survey at the Matsukawa geothermal system was conducted. The result shows that SP monitoring allows us to realize the hydrological characteristic of each observation point for both steam dominated and water dominated reservoirs.
