(23-08-2021) A PhD position on Induced seismicity at the Balmatt geothermal doublet: Investigate fluid induced seismic triggering mechanisms by means of seismic analysis and geomechanic modelling

Available PhD position on “Induced seismicity at the Balmatt geothermal doublet (northern Belgium): Investigate fluid induced seismic triggering mechanisms by means of seismic analysis and geomechanic modelling”.

The PhD is funded by Ineris (Institut national de l’environnement industriel et des risques) and VITO (Flemish institute for technological research), in cooperation with the University of Strasbourg.

 VITO initiated a geothermal project on the former Balmatt industrial site in Mol (Belgium) with drilling commencing in 2015. Several seismic events with magnitude -1 < ML < 2.2 were recorded during the first test operations, carried out between December 2018 and June 2019. Operations on the site have been resumed in April 2021 in the framework of a research project to provide new and better insights in the hydraulic and seismological reservoir characteristics.

 As part of this research project, the PhD thesis will focus on the evaluation and quantification of governing trigger mechanisms of seismicity finalized in the construction of a (“conceptual”) hydromechanical reservoir model.

The thesis work will be divided into two fields: geophysical (seismic) data analysis and geomechanics modelling. The balance of effort of both analyses will strongly depend on the quality and volume of the acquired seismic dataset during upcoming circulation tests as well as on the background and interests of the candidate.

We are looking for a motivated candidate with good knowledge of seismology and geomechanics, preferably with programming and signal processing skills. Start date is foreseen in October to November 2021. The candidate will be based at the Ineris lab in Nancy (France), but will also spend time in Strasbourg (France) and Mol (Belgium).
