Summary of our activities
In the recent years, modeling approaches have become one of the principal means by which the gaps between current basic process knowledge and predictions in environmental sciences can be bridged. The scientific challenges that must be addressed in these modeling approaches include the multi-scale description of highly heterogeneous systems with discontinuities in physical and chemical properties, and coupling of thermal, hydrological, chemical, mechanical and biological processes. Pores are the location where these couplings take place.
The objective of our group “Porous media” is the development of integrated predictive reactive transport modeling approaches that cover a large range of pressure, temperature and salinity conditions, in order to encompass supergene to hydrothermal conditions, in the presence of fresh water as well as brine. To this end, our team explore mechanistic couplings of basic processes with experimental and numerical modeling approaches.

After a master thesis on shale permeability in relation to hydraulic fracturation, Céline did her PhD thesis at the Ecole Normale Supérieure in the Laboratoire de Géologie (defended in October 2014). She experimentally studied, under the supervision of Yves Guéguen and Jérôme Fortin, the crack behavior in glass under geological reservoir conditions for radioactive waste storage. Her study was focused on geophysical crack characterization (through wave velocity and acoustic records) and geomechanical understanding of the subcritical crack propagation under THMC coupled effects. Céline went then in Lausanne University (Institut des Sciences de la Terre) for a postdoc where she worked on numerical modelling of wave attenuation to characterize crack connectivity for geothermal development in Switzerland. She became a maître de conférence at Orléans University in September 2016, in the Laboratoire de Mécanique Gabriel Lamé (in Civil Engineering) where she continue to work on multi-geophysical approach for permeability characterization of cracked materials. Because of her sensitivity to geoscience issues, she went to ISTO in order to develop her research interests in porous rocks and for applications to geological reservoirs and natural risks.

FRAMATI (2019-2023). Microscale modeling of fracture-matrix interactions under reactive two-phase flow
The objective of the FraMatI project is to improve our fundamental understanding of fractures alteration and to develop predictive capabilities of reactive multi-phase flow in complex geological formations. The scientific strategy relies on a systematic multi-scale analysis of the fracture-matrix interactions starting at the micro-scale by means of numerical modeling and microfluidic experiments.

CATCH (2018-2022). Dynamic characterization and modeling of coupled structural - chemical - and transport processes: a multiscale approach
The CATCH project aims at estimating changes of transport parameters in geological media in response to porosity evolution. The long-term effectiveness of deep subsurface storage systems largely relies on our understanding and modeling capability of key relationships between natural media and engineered components. Changes in the mineral matrix due to dissolution-precipitation reactions due to perturbations caused by geological applications can lead to changes in the macroscopic transport properties of the geological medium. Predictions can be made by considering transport processes coupled to chemical reactivity, but current reactive transport models (RTM) have severe limitations due to an incomplete understanding and quantification of the underlying mechanisms and processes. Using a combination of multiple methods and multi-scale characterizations, we aim at making a fundamental step forward in the predictive ability of RTM based on bridging the pore and continuum scales.

CapFrac - CAPillary forces transmission from nanopores to FRACtures. An experimental approach. (TELLUS 2020).

CH-MOD - Hydro-chemical-mechanical coupling in clay materials (TELLUS 2019).
The study of transient stages of the clay response to external complex chemical perturbations would benefit from a coupled reactive transport/mechanical modeling approach. The development of such models necessitates that the predictions can be tested against experimental data that covers, not only one of the hydrological, chemical or mechanical aspects, but the three of them concomitantly. In this respect, the CHMOD project aims to build and test a specific oedometer cell able to measure the swelling pressure of clay samples, and to concomitantly visualize, in situ, the evolution of how the microstructure is organized through state-of-the-art synchrotron radiation techniques.

Alliance 2019 - Geochemical aspects of CO2 sequestration: experiments and numerical simulations
Ensuring a secure supply of energy that is affordable for consumers while helping the UK and France to meet their 2030 decarbonisation targets (57 % below 1990 levels for the UK, 40 % for France) is a question that remains unsolved. In this context, the objective of this collaboration is to join the effort of Heriot-Watt University (HWU, Edinburgh, U. K.) and the Institut des Sciences de la Terre d'Orléans (ISTO, France) in developing an automatic workflow to investigate the physics of Carbon Capture and Storage (CCS) in geological reservoirs. The scientific goal of the project is to investigate the geochemical properties of the CO2-brine mixture (exsolution, dissolution, precipitation) during laboratory flow experiments on manufactured and 3D printed micromodels, underpinned by state-of-the-art numerical simulations, and to assess their effects on the macroscopic system behavior in order to develop appropriate upscaling approaches from the pore to the field scale.

PROCOPE 2019 - Multi-scale experiments for understanding coupled reactive transport processes
The goal of the collaboration is to join the efforts of a German (IEK-6, Forschungszentrum Jülich (FZJ)) and a French partner (Institut des Sciences de la Terre d'Orléans (ISTO)) on the development of realistic descriptions of complex coupled processes in numerical models for reactive transport simulations that are applicable e.g. in the fields of safety assessments of nuclear waste repositories, oil and gas recovery, or the evaluation of contaminant transport in the subsurface. The motivation is to understand and quantify changes of transport parameters (e.g. permeability, diffusivity) in geological media in response to spatial and temporal porosity and microstructure evolution. The scientific goal of this work is to investigate geochemical processes at the pore scale and in confined media (in particular dissolution/precipitation processes) and to assess their effects on the macroscopic system behavior with respect to its (physical) solute transport properties, in order to develop appropriate upscaling approaches for implementation in continuum scale models. We will develop experiments which serve to gain insights into the relevant pore scale processes and that will be further used to develop mechanistic models to describe the system evolution.
Our aim is to conduct experiments at different scales using plug through column experiments (cm scale) and using innovative microfluidics experiments (µm scale, pore-scale). We will evaluate the consequences of mineral precipitation and dissolution in porous media on the evolution of the porosity and of the macroscopic transport properties of the media.
A microfluidic study of the physical and chemical mechanisms induced by CO2 injection in deep saline aquifers (Ph.D. Student: Mahdi Mansouri ; Supervisors: Sophie Roman & Mohamed Azaroual)
Carbon dioxide capture and storage (CCS) in deep saline aquifers is a promising mitigation technology to reduce CO2 emissions. The CO2 injection in deep geological structure induces multiphase reactive flows processes. The repartition of the non-wetting phase (CO2) in the pore network of permeable reservoirs and key trapping mechanisms are functions of the physical and chemical properties of both fluids (wetting and non-wetting) and the petrophysical of the targeted geological reservoir. A better understanding of two-phase flow mechanisms is the prerequisite for predicting fluid distributions and control/improve the injectivity of the wells. In addition, the injection of CO2 in saline aquifers will acidify the brine, thus increases its geochemical reactivity potentially changing the pore structure and the petrophysical properties of the reservoir.
The PhD project is based on a multiscale strategy using microfluidics experiments in order to improve our knowledge of the key mechanisms of CO2 injection and sequestration in deep saline aquifers, and to identify the relevant couplings between phenomena at different scales under various flow rate, temperature, pressure, wetting and salinity conditions. Microfluidics experiments will be carried out using the GLoC (Geological Lab on a Chip) concept. Microfluidics systems are transparent pore networks that allow direct and in situ visualizations (optical and spectroscopic technics) of pore scale and phase-interface mechanisms (i.e. fluid distributions, mixing between contrasted fluids, geochemical reactions, etc.). Microfluidics experiments will be associated with high-resolution imaging and image processing techniques in order to obtain quantitative data on pore scale mechanisms. The processing of the obtained results is the delicate step of the work allowing kinetic and interfacial properties parameter evaluation, as well as numerical modeling of two-phase flow and reactive transport.
Kinetics and mechanisms of anion exchange processes in nanocrystalline green rusts (Ph.D. Student: Myriam Agnel; Supervisors: Christophe Tournassat & Sylvain Grangeon)
A significant part of soil reactivity is due to layered materials such as clay minerals or oxides. Fougèrite is a layered double hydroxide discovered in a hydromorphic soil and first described by Trolard et al. (2007). This mineral is the naturally occurring form of green rusts, a corrosion product of iron pipes anteriorly described by Keller (1948). The minute size of Fougèrite leads to a large surface to volume ratio, and hence a large density of reactive border sites. This reactivity is reinforced by the lamellar structure, meaning that it is built of layers - charged positively due to isomorphic substitution and vacancies - separated by an interlayer space in which anion can be incorporated to compensate for the layer charge. This particular structure makes Fougèrite a major player in the control of (oxy)anions (e.g. Cl-, NO3-) cycling in hydromorphic soils. Fougèrite stability, and thus presence, in soil is largely controlled by redox conditions. Consequently, the presence of Fougèrite is controlled by external forcing in soil systems such as seasonal cycles or climatic changes. The quantification of the reactivity of Fougèrite is thus a key aspect in our understanding of present and future (bio)geochemical cycles of anionic compounds in soils.
The objective of this research project is to develop thermo-kinetic models of ion exchange on green rust surfaces calibrated with structural and chemical experimental data. To date, very few studies have focused on the link between crystal structure and reactivity of green rusts. A detailed study of the structure combined with ion exchange lab experiments and multi-scale numerical simulations are necessary to decipher mechanisms at work in this system.

Chemical-mechanical coupling in unsaturated porous media : Capillary tension – Crystallization pressure (Ph.D. Student: Claudie Hulin, December 2017)
The alteration of porous media in drying conditions is generally attributed to the pressure exerted by growing salts from the poral evaporating solution against the pore wall (crystallization pressure). In drying conditions, the water retained by capillarity in nanometric pores is under absolute negative pressure. Water under capillary tension exerts a mechanical traction against the pore walls but also modifies the chemical equilibria and so rock-fluid interactions. Crystallization pressure and capillary tension, which are physical processes, are both induces by the disequilibrium between poral water and dry air.Salt crystallization experiments in microtubes (Na2SO4, NaCl) show some favorable conditions for crystallization pressure - in terms of supersaturation and geometry – which is transient and brutal. A second series of experiments shows that capillary tension, generated by a nanometric liquid air interface, can be transmitted to a macrovolume of aqueous solution in a particular geometric system built with salts. The tensile state is metastable (superheated), but long enough to modify significantly the chemical budget of the system and to see mechanical effects. The brutal relaxation of the superheating state by vapor nucleation induces a rapid salt supersaturation which is the driving force of the crystallization pressure.The salt growth (during evaporation) and capillarity cooperate in drying conditions to alter porous media.During climate cycles (especially humidity) they control and induce transient and brutal events which mark the end of metastable states (superheating and salt supersaturation).
