| Zusammenfassung |
| The processes and conditions underpinning induced seismicity associated with deep
geothermal operations are still not sufficiently well understood to make useful predictions as
to the likely seismic response to reservoir development and exploitation. The empirical data
include only a handful of well-monitored EGS experiments; models are consequently poorly
constrained. Unfortunately, data sets of well-monitored deep hydrothermal experiments are
missing and empirical constraints of induced seismicity models for these cases do
not exist. Given that the majority of the projects underway or planned in Europe
are of the hydrothermal type, there is hope that this deficit can be remedied in the
near future through a close cooperation of geothermal industry, science and public
authorities.
The GeoBest project was initiated in Switzerland to facilitate the dialog between
geothermal industry, science and public authorities. The Swiss Seismological Service (SED)
is implementing the GeoBest project on behalf of the Swiss Federal Office for Energy
(SFOE) to provide cantonal and federal authorities with guidelines on how to handle seismic
monitoring and hazard in the framework of the environmental risk assessment. Within
GeoBest, selected pilot projects in Switzerland will be supported during the necessary
seismic monitoring of natural and induced seismicity. GeoBest supports the pilot project in
the first two years, that are most critical with respect to the financial risk, by providing
seismological instrumentation from the GeoBest instrument pool and partial financial support
for the operation of the seismic monitoring network. In return the pilot projects grant SED
access to project data needed for seismic hazard assessment and the development of best
practice guidelines. These types of collaboration offer the unique opportunity to
collect high-quality seismological data and, by combining them with relevant project
data, to gain first hand practical experience for the development of best practice
guidelines. |
