My main interest lies in the understanding of the origin of geophysical observables (seismic and electrical signals) and how these observables are affected by geochemical reactions.
I work on geological and industry-related problems where rock and reservoir properties, fluid flow and geochemical reactions are coupled and time-dependant. I use a combination of geophysical and geochemical tools including classical practices in experimental rock physics, various characterization and imaging techniques at various scales, aqueous chemistry methods and reactive transport modeling. Specifically, I combine experiment, theory and modeling to address fundamental, subsurface-engineered or petroleum-related problems, at scales from the pore scale to the reservoir scale.
My past and current projects can be broadly grouped under three main reasearch areas:
- quantitative link between microstructure of rocks and their physical and chemical properties;
- improved 4D seismic interpretation for geological carbon sequestration and CO2-EOR;
- weathering and diagenetic alterations of rocks.
