One of the critical challenges in Carbon Capture and Storage (CCS) is to ensure that the CO2 is stored safely in the reservoir over a long time. The approach is to monitor the stability based on seismic surveys that measure the change in seismic wave propagation as the amount of stored CO2 increases...

Progress towards a net zero carbon economy involves subsurface activities, such as geothermal energy production and geological storage of carbon dioxide and hydrogen, that disturb tectonic stresses in the Earth's crust. Seismicity induced by such stress perturbations is associated with risk from dam...

Fluid extraction from geological formations for purposes of subsurface utilization leads to a pore pressure drop in reservoirs and potentially to compaction and seismicity. The geomechanical behaviour, and thus production-related compaction, of siliciclastic reservoirs is governed by the composition...

High strain rates generated by moderate to large earthquake rupture cycles cause wall rock fragmentation, brecciation, and in-situ shattering, and enhance fluid flow in damage zones of continental thrust faults. This process reduces the rigidity of the hanging wall and raises the question of how han...

Neutron imaging provides direct observation of evolving water–air and deuterated water–normal water exchanges in flow experiments performed on a laboratory-deformed, microporous, extremely fine-grained laminated limestone. First D2O, then H2O, are injected into the sample base, and the l...

Volcanoes are heterogeneous and unstable structures prone to collapse and, as such, they present a physical and economic risk to the population living in their proximity. Hydrothermal alteration, common to many volcanoes, changes rock strength and is thought to be involved in the process of stabilit...

The rocks forming a volcanic edifice or dome are typically saturated or partially- saturated with water. However, most experiments aimed at better understanding the mechanical behaviour of volcanic rocks have been performed on dry samples, and therefore most large-scale models designed to explore vo...
