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.
