Towards controlling induced seismicity

AuthorsVilarrasa, Víctor
Issue Date30-Apr-2019
AbstractInduced seismicity has become widespread as a result of fluid injection in the subsurface for energy related activities, such as geothermal energy, geologic carbon storage and subsurface energy storage. If felt, induced seismicity has a negative effect on public perception and may jeopardize wellbore stability and adjacent infrastructure, which may eventually lead to the cancellation of geo-energy projects. Thus, forecasting injection-induced earthquakes is a big challenge that must be overcome to successfully deploy geo-energies to significantly reduce CO2 emissions and thus mitigate climate change and reduce related health issues. In this presentation, it will be shown how induced seismicity may be controlled through 1) understanding the processes that induce it and 2) reducing uncertainty by characterizing the subsurface, in order to develop methodologies to manage injection pressure and temperature.
