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...

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 flow and heat transfer between wells by increasing the permeability and transitivit y of the reservoir. This is achieved by injecting high-pressure fluids (normally water) in order to increase the apertures of existing fractures, enhancing theirsliding and/or generating new ones. However, this technique induces low-magnitude seismicity that occasionally results in damageat the Earth's surface. Numerical simulation sable to reproduce the hydro-thermome chanical behaviour of geological reservoirs are anessential too for the evaluation and fore casting of induced seismicity in such systems. In this study, the numerical code CFRAC is used to systematically evaluate how the orientation of faults with respecttoth estress field influences seismicity , the injection rate and the fracture sliding behaviour |
