Project Title: Long-term seismic monitoring of Dutch geothermal-well activities with surface seismometers
Host Institutions: TU Delft, RWTH Aachen, EBN
Supervisory Team: Kees Weemstra, Deyan Draganov, Florian Wellmann, Jorien Schaaf, Mara van Eck Van Der Sluijs
Start date: 15.3.2021

ESR02 Objectives:

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. 

Research Update

For improving the safety in geothermal operations, I am developing a set of tools for monitoring the seismic activity around geothermal projects.

Currently, I am working on three different projects: I) the development of a tool for correcting clock errors of seismic arrays before doing any monitoring activity. I presented this work in the EGU General Assembly 2021, and the manuscript is under current development. ii) Processing the seismic data collected around a shallow geothermal field in Kwintsheul, Netherlands, where a microseismic event has been detected. I submitted an abstract about this work to the 2022 European Geothermal Congress. iii) To characterize the geological structures with a potential seismic hazard, I am developing a moment tensor calculation tool.
