The project DEEPEN-CH represents the Swiss contribution to the international GEOTHERMICA project DEEPEN, coordinated by Reykjavik Energy. DEEPEN started formally in December 2020 and ended in December 2023, more information is found at:
https://www.or.is/en/about-or/innovation/deepen/. DEEPEN aims to better understand the roots of magmatic geothermal systems through observations and modeling, as well as to develop techniques and work flows to find such deep and superhot resources (Fig. 1). The project is a multinational collaboration among several universities, institutes, and energy companies. In DEEPEN-CH, we exploit the opportunities represented by DEEPEN for the Swiss context. Embarking on production for any resource is a high-risk endeavor because there is only inferred and uncertain knowledge of the subsurface. To reduce the risk of unsuccessful drilling or induce seismicity, it is of
critical importance to improve seismic imaging methods such that they can better aid in a-priori resource characterizing and seismic risk assessment. DEEPEN-CH is divided into three work packages: Dense seismic network deployment and operation in Iceland (WP1), validation and improvement of imaging methodologies (WP2) and knowledge transfer to target applications in Switzerland (WP3).
