Testing of the hydro-mechanical behaviour of shales

Shales are among the most commonly considered geomaterials in current energy-related geomechanical investigations, as they are involved in engineering applications such as the unconventional extraction of natural gas, CO2 sequestration and nuclear waste geological storage. A deep understanding of their hydro-mechanical behaviour is of primary significance for such applications. In this paper selected results on the water retention behaviour and on the high pressure oedometric compression behaviour of shales are presented.
