Geophysical methods allow exploring the subsurface and rely on physical properties of rocks. In
the case of seismic tomography, which is the most utilized geophysical method, the knowledge
of rheology is pivotal to infer the structure and composition of the Earth interior. Nonetheless,
very often geophysicists treat geo-material as purely elastic overlooking at the role of
anelasticity. I will present a dataset of seismic-wave attenuation measurements performed on
partially saturated Berea sandstone and model the results according to poroelastic theories.
The models help to constrain the physics behind the propagation of seismic waves and can be
used to upscale the results to reservoir scale problems.
Dr. Tisato received his PhD in Engineering (geophysics) from ETH Zurich. He is currently an Assistant
Professor, Geophysics, at the University of Texas at Austin – Jackson School of Geosciences and
Department of Geological Sciences.
