Abstract

Summary

Conventional lab scale tools are adequate to access some experimental data related to CO2 geological storage in deep saline aquifers. However, they are lacking from in situ characterization techniques, thus limiting the monitoring and the understanding of the various involved processes. Therefore, new methods are needed to investigate deeply the fundamental mechanisms associated with these four trapping mechanisms. In this context, microfluidics approaches have bring several advantages over conventional experimental means, including fast screening of the parameters, fast heat and mass transfer and the ease of implementation of various characterization techniques. By adapting such approaches to porous media, our team has demonstrated the fabrication and use of the first high pressure / high temperature microreactors, able to withstand harsh conditions up to 20 MPa and 400°C, which were adapted to studies dealing with fluidic within porous media, so called “Geological Labs on Chip – GLoCs”. These tools are at the core of the collaborative project CGSµLab N° ANR-12-SEED-0001 funded by the French national research agency (ANR). We illustrate here after some key results obtained from the use of GLoCs coupled to optical and spectroscopy characterization methods.
