T81. New challenges in reservoir and seal rocks characterization

-

Congressi SGI-SIMP

Reservoir and seal rock mechanics are having an increasing importance in georesources studies. Geothermal reservoirs characterization requires different information with respect to those for Oil and Gas. Cyclic hydrogen injection into and withdrawal from the geological formations, may induce fatigue changing rocks mechanical properties. Moreover, recent failures in prediction of mechanical properties of the modelled gas-hydrate reservoirs, highlight the importance of characterizations based on actual data. At the laboratory scale, petrophysics and rock deformation experiments allow to measure changing properties and to reproduce the mechanisms acting at different boundary conditions. Field-scale observations such as structural and facies analyses, GPS data and subsurface measurements provide larger scale information. Computational modelling can be then used to test the reliability of laboratory and field data; however, such integration is challenging. Thus, new laboratory and field scale techniques and new models need to be tested to properly predict the mechanical behavior and the associated risks of reservoir and seal rocks. This session aims to bring together researchers focusing on the reservoir and seal rocks characterization at different scale and with different expertise such as for example sedimentologist, structural geologists, seismologists, or geophysicists. Cutting-edge applications to the challenges opened by new georesources are greatly encouraged.
