We are seeking a postdoctoral researcher for a two-year position funded by NWO, focusing on the monitoring of thermally induced seismic events in geothermal energy extraction. As geothermal energy plays a crucial role in sustainable heating, understanding the associated seismicity is vital for project acceptance. This project aims to answer the question: 'When can reservoir cooling in sedimentary geothermal projects lead to significant seismic activity?' The research will integrate laboratory experiments, geophysical field monitoring, and numerical reservoir modeling.

The Role

The successful candidate will undertake three primary tasks: performing centroid-moment tensor inversions for small induced seismic events in the Groningen area, developing an inversion strategy tailored for small events and sparse seismic data, and conducting centroid-moment tensor inversions for low-magnitude events in geothermal projects, focusing on the volumetric component of the moment tensor.

Responsibilities

• Conduct centroid-moment tensor inversions for small (M < 1) induced events in the Groningen area.
• Develop an inversion strategy suitable for small events and sparse seismic data.
• Perform centroid-moment tensor inversion for low-magnitude induced events in geothermal projects, linking results to geothermal-induction theory.

Requirements

Need-to-haves:

• PhD in Geophysics, Physics, Mathematics, Earth Sciences, or a related field.
• Experience in linking models to field data.
• Strong understanding of seismic wave fields and mechanics.
• Ability to work independently and collaboratively within a multidisciplinary team.
• Excellent written and verbal communication skills in English, with a track record of publishing in peer-reviewed journals.

Nice-to-haves:

• Experience with seismic processing and inversion techniques.
• Familiarity with finite difference wave-equation solvers like SeisSol or SPECFEM3D.
• Interest in advancing geothermal energy.
