This Work Package is dedicated to developing and testing innovative and emerging surface and borehole-based monitoring technologies for application at deep geothermal sites. WP1 will exploit new kinds of sensors and arrays of sensors that offer greatly improved observational and imaging capabilities for enhancing our understanding of the generation process of induced seismicity. In particular, we will assess the performance of two novel surface seismic networks (Task 1.1) and state-of-the art borehole instrumentation (Task 1.2). These emerging technologies will be tested at active and developing deep geothermal sites in the Rhine graben (France and Germany, Task 1.3) of Europe, in close proximity to the beneficiary and partner locations, before possible mobilisation and application at Forge. In addition, these European demonstration sites represent different levels of industrial development from active geothermal exploitation (e.g. Soultz) to site development (e.g. Strasbourg) to initial planning stages (e.g. Weisweiler, Hagen, and Bochum).
