Research group: Groundwater and Hydrogeochemistry
My current research interest is in combining attributes of induced seismicity, such as derived source mechanisms, models of fracture generation, event statistics, pumping information, etc. to develop a better understanding of how induced seismicity is generated and propagates for use in evaluating seismic hazards and developing more safe and efficient stimulation. Additionally, correlating temporally varying microseismic activity to subsurface models may give insight into how fracturing develops and what observations can be used to monitor and optimize treatments in unconventional and geothermal plays.
GEoREST (ERC StG)
GEoREST aims at developing a novel methodology to predict and mitigate induced seismicity.
GEoREST aims at developing a novel methodology to predict and mitigate induced seismicity. Fluid injection related to underground resources has become widespread, causing numerous cases of induced seismicity. If felt, induced seismicity has a negative effect on public perception and may jeopardise wellbore stability and infrastructure, which has led to the cancellation of several projects. Therefore, forecasting injection-induced earthquakes is a big challenge that must be overcome to deploy geo-energies to significantly reduce CO2 emissions and thus mitigate climate change and reduce related health issues.
