Induced Seismicity in pressurised single fractures: a numerical approach

The exploration and exploitation of deep geothermal reservoirs hass ig ­nificantly increased during the last years. These reservoirs use heat exchange to produce heat or electricity. The so-called Enhanced Geothermal Systems (EGS) are characterize by a stimulation phase that aims to increase fluid f...
