Advances in petrophysics and rock-physics: integrating models, laboratory experiments and field studies

Convener: Damien Jougnot
Co-Conveners: Ludovic Bodet, Lucas Pimienta

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.
