Abstract
The GEISER (Geothermal Engineering Integrating Mitigation of Induced SEismicity in Reservoirs) project is co-funded by the European Commission to address the mitigation and understanding of induced seismicity (IS) in geothermal engineering. The aim of the project is to contribute to the improvement of the concept of EGS by investigating the role of IS, which is twofold: 1. as an instrument to image fluid pathways induced by hydraulic stimulation treatments, which has been done to some extent in previous projects; and 2. as an implication of such treatments to potential seismic hazards. Work started in 2010 by addressing four major points: - Analysis of induced seismicity - Understanding the geomechanics and - Consequences of induced seismicity - Strategies for the mitigation of induced seismicity Within the first year of the project, a number of reference sites were defined where data sets with seismic and downhole data are available for further processing and analysis. In addition, laboratory experiments and mechanical models as well as hazard assessment tools are developed on the basis of existing data. At the end of the project, guidelines for regulatory bodies will present the basis for future licensing procedures of geothermal projects.
