The GEISER project stands for Geothermal Engineering Integrating Mitigation of Induced Seismicity in Reservoirs. It started at the beginning of the 2010 after successful contract negotiations with the European Commission. EC funding of € 5.3 Mio was granted for 3.5 years. The project addressed several of the major challenges the development of geothermal energy is facing, including the mitigation of induced seismicity to an acceptable level.
The specific goals of GEISER are:
- to understand why seismicity is induced in some cases but not in others
- to assess the probability of seismic hazards depending on geological setting and geographical location
- to propose licensing and monitoring guidelines for local authorities, including a definition acceptable ground motion levels
- to investigate strategies for soft stimulation that sufficiently improve the geothermal reservoir’s hydraulic properties without producing earthquakes that could be felt or cause damage
The project is coordinated by GFZ and involve 12 additional partners. GEISER is divided into 7 work packages including Compilation of induced seismicity data from geothermal sites, Analysis of Induced Seismicity, Understanding the Geomechanical Causes and Processes of Induced Seismicity, Seismic Hazard Assessment, Strategies for EGS operations with respect to Induced Seismicity (Mitigation) and Dissemination.
Between 2010 and 2012 I was involved in GEISER Work Package 3: Analysis of Induced Seismicity, where different seismological approaches has been applied and further developed to analyse data sets of induced microseismicity from geothermal areas. During this time I analyzed microseismic data from Berlin (El Salvador) and The Geysers (California, USA) geothermal fields. The analysis of data from The Geysers geothermal field is continued.
