Physical properties of Tunnel rock samples

 The objective of the project is to evaluate the rock mas integrtiy of rock samples, taken from a tunnel project, by using geophysical methods, including petro-physical and microstructural investigations.

Effect of tunnel fires on the integrity of rocks

The objective of the project is to evaluate the effect of high temperature on the rock mas integrtiy of rock samples, taken from a tunnel project, by using laboratory methods such thermal cracking, including petro-physical, and microstructural investigations.

Understanding earthquakes in the laboratory: Mitigation of induced seismicity in enhanced geothermal systems

In the context of geothermal energy, the objective of the project is to understand induced earthquakes (“man made earthquakes”) by reproducing them in the laboratory.

Fault reactivation in deep geothermal reservoir

In the context of geothermal energy, the objective of the project is to study how viscous fluids can influence the reactivation of faults in deep geothermal reservoirs. The project will be tackle through an experimental aproach where fluid injection of viscous fluid in fractured reservoir will be reproduce at laboratory scale.

Electrical properties of Opalinus Clay: Applications for nuclear waste storage

In the context of deep geological disposal, the objective of the project is to study how the electrical properties are influenced as a function of water saturation in shale rocks. By performing laboratory testing, the electrical properties of Opalinus Clay will be measure at different saturation conditions.

Mechanical characterization of an unstable rock mass

Unstable rock masses can represent a serious threat to highly populated areas and can cause relevant damages. In order to effectively mitigate the hazard from rock mass instabilities, a detailed knowledge of the mechanical properties of the involved rock volume is required to forecast the localisation of deformation and the pre-failure mechanisms. Here we propose to characterise the mechanical fatigue of the unstable granitic cliff of Madonna del Sasso (NW-Italy). The work comprises experimental testing + data analysis + bibliographic study.

Effect of water on fault healing and earthquake recurrence

Anthropogenic earthquakes are today one of the main challenges for the development of Geo-energy, and so, for the access to sustainable, affordable clean energy.

Human made earthquakes often result from fluid injections into the fractured rock mass but the exact interactions between fluids and faults are not properly understood.

Faults strengthen or heal with time in stationary contact and this healing may be an essential ingredient for the earthquake recurrence. Here we propose to understand the role of water on healing mechanisms of carbonate and silicate bearing fault.

The work comprises bibliographic study + data compilation and analysis  + modelling of experimental data.

This work is relevant for geothermal energy exploitation, CO2 sequestration, and production of deep hydrocarbons
