Geophysical methods have a great potential for characterizing subsurface
properties and processes to inform geological, reservoir, hydrological,
and biogeochemical studies. In these contexts, the classically used
geophysical tools only provide indirect information about subsurface
heterogeneities, reservoir rocks characteristics, and associated
processes (e.g. flow, transport, biogeochemical reactions).
Petrophysical relationships hence have to be developed to provide links
between physical properties (e.g. electrical conductivity, seismic
velocity or attenuation) and the intrinsic parameters of interest (e.g.
fluid content, hydraulic properties). In addition, geophysical methods
are increasingly deployed as time-lapse, or even continuous, and
distributed monitoring tools on more and more complex environments. Here
again, there is a great need for accurate and efficient physical
relationships such that geophysical data can be correctly interpreted
(e.g. included in fully coupled inversions). Establishing such models
requires multidisciplinary approaches since involved theoretical
frameworks differ. Each physical property has its intrinsic dependence
to pore-scale interfacial, geometrical, and biogeochemical properties or
to external condition (such as pressure or temperature). Each associated
geophysical method has its specific investigation depth and spatial
resolution which adds a significant level of complexity in combining and
scaling theoretical developments with laboratory studies/validations
and/or with field experiments. This session consequently invites
contributions from various communities to share their models, their
experiments, or their field tests and data in order to discuss about
multidisciplinary ways to improve our knowledge on reservoir and near
surface environment.
