In the last few years, major and damaging earthquakes were felt in regions supposedly affected by a low rate of natural seismicity. Such events have become an extremely important topic of discussion in both Europe and North America, since several major events were associated to industrial activities. The main focus of this proposed research is the study of induced seismicity during exploitation of natural underground resources. More specifically, this proposal focuses on one side on a detailed understanding of the deep fault and/or fractures reactivation associated with the fluid injection. On the other side, the proposed research plans to investigate the mitigation of large magnitude induced seismicity, which may pose at risk the affected population and structures, as well as acting as obstacle to the development of new techniques for the exploitation of deep underground resources. First I aim to understand the physics associated with the induced seismicity caused by anthropogenic activities. Secondly, the project aims to investigate in which conditions fluid-induced seismicity can be used as a tool. For example, the shearing process of fault and fracture, or the creation of new fractures, are needed to increase the permeability, and hence to enhance the fluid circulation at depth, eventually resulting in a more efficient energy production. However, such processes may, at the same time, produce seismicity that can be felt by local population. Open questions are:• How is the induced seismicity affecting the growth of a geothermal reservoir? When does it act as a potential seal breaching during storage operation? • Is it possible to use induced seismicity to develop a high permeability system, while constraining the earthquakes maximum magnitude? Or can a gas be stored in a safe (no seismic) way?Understanding the fundamental processes will help in finding new methods to safely extract energy, whose request nowadays is constantly increasing. I propose to address the above open questions by theoretical studies, laboratory, and applied field work. I plan to use data collected from on-going experiments (laboratory and in-situ) to improve numerical models. Numerical tools to be used include: thermo-hydromechanical modeling (THM), discrete fracture network (DFN), and statistical, as well as hybrid simulators. This research plan comprises of two phases. During phase I the numerical models will be calibrated in order to mimic and bridge processes inducing seismicity at different scale. Thanks to the unprecedented amount of data that will become available under the SCCER-SoE experiments umbrella and other closely related projects, I aim to:1. Use data from ongoing lab experiments at Rock Deformation Lab of the ETH Zürich (part of SCCER-SoE, project funded by SNF) to understand the shearing process of sample (up to 0.1 cm) during fluid injection by studying the acoustic emission and by evaluating the permeability changes during stimulation;2. Use data from ongoing deep underground laboratory for experiments on in-situ hydrofracturing (1 m) and stimulation of a 10 m scale region (DUG-deep underground laboratory, Grimsel, part of SCCER-SoE), as well as data from in-situ fault slip after injection of fluids (FS experiment, Mont Terri);3. Develop empirical relation for seismicity-permeability changes based on experiments, as well as implement physics-based model of fault reactivation and seismicity propagation to be included in the numerical modeling;4. Test the developed model on data from pilot projects (100s m) for both deep geothermal energy and CO2 sequestration, as well as model generic scenarios for application of deep underground GeoEnergy in Switzerland at reservoir scales (1000s m).Phase II will feature a novel concept for performing experiment, which has a large implication for future large-scale projects. The goal is to collaborate with the Rock Deformation Laboratory at ETH Zürich in planning a lab experiment coupled with numerical simulations, which update parameters of the experiments in real time to modulate the expected observables (e.g. seismic acoustic emission, fluid flow, and temperature).
