EASYGO (C. Weemstra)

Processes associated with the injection and extraction of water in Dutch geothermal reservoirs will be monitored using a long-term network of 3-component short-period seismometers (low-frequency geophones) installed at the surface (or 1-2 m below the surface) close to the DAPwell and other Dutch geothermal wells. The data will be provided by the industry partner EBN and will represent passive data. In this geothermal context, we will develop an inversion strategy for the source mechanism associated with detected seismic events. We will also use the data to investigate the potential of passive seismic sources (ambient noise, regional and teleseismic events) for imaging the subsurface structures with seismic-interferometric techniques.
