Full textClay minerals are ubiquitous at the surface of the Earth and can influence, among other properties, the permeability and the ionic exchange properties of soils and rocks due to their platy shape and their most often (sub)micrometric size. Thus, studying clay porous media is of prime importance for different research fields such as: the exploitation and conservation of natural resources, the tracking of pollutants or CO2 storage. While the physicochemical properties of the surface of clay minerals control the adsorption-desorption mechanisms of water and ions, it is the porosity and the anisotropy of the poral network that govern diffusion phenomenon within clay porous media. In this respect, the work presented in the following doctoral thesis focuses on the characterization of clay particle orientation and its influence on anisotropic diffusion properties of water in the associated pores. A first part of this manuscript gathers systematic structural analyses of various model and natural samples. One study presents the analyze of experimental and simulated stackings made from sedimented discs with a unique particle size. Results underlined a simple correlation between the particle orientation anisotropy and the poral network anisotropy. Then, an other study was performed on experimental media made of pure clay minerals for various mineralogical compositions and various preparation methods. Based on this data, a reference function was proposed to describe the experimental orientation distribution functions and was successfully applied to three natural porous media. These results aim to facilitate and improve the description of the preferential orientation of clay particles as part of a geometrical characterization of clay porous media. A second part of this manuscript try to describe the link between the anisotropy of the solid phase, previously characterize by the particle orientation, and the prediction of water diffusion coefficients in these clay porous media. A study using both simulated and experimental media was performed on kaolinite porous media presenting contrasted anisotropy and with all other parameters held equal (porosity of the medium, size and shape of particles). Results show a variation of water diffusion coefficients with a factor 2 in the longitudinal direction, compared to the compaction axis, and an anisotropic diffusive ratio varying from 1 (isotropic) to almost 5 (most anisotropic medium analyzed). Then, complementary measures allowed establishing a modified version of Archie’s law that predicts water diffusion coefficients from the porosity/particle orientation couple for a range of porosity of 30-60%. These results aim to improve the description of the orientational anisotropy of clay particles in macroscopic diffusion models of water. Simultaneously, the influence of a salinity gradient and the roles of interparticular and interfoliar porosities are discussed for the diffusion of water, Na+, and Cl- within vermiculite media (charged media with double porosity) for known structural organizations

Full textThis thesis is an experimental study of flow and transformation of porous media, where we study both fast and slow transformation of the media due to fluid flow. The fast process is mechanical deformation and channel formation due to high fluid pressure, and the slow process is chemical evolution of fractures. In the study of fast deformation, we perform experiments where air is injected at a constant overpressure into a saturated or dry granular medium. From recorded images, we characterize Saffman-Taylor like invasion patterns, surrounding deformation of the medium, flow regimes, and channel growth dynamics. Pore pressure is evaluated numerically, and used to characterize the rheology. In the study of slow transformation, we perform experiments where distilled water is injected at a constant flow rate through a fractured chalk sample. By comparing fracture apertures measured before and after experiments, we study the evolution of fractures for different durations of reactive flow

Full textThe thesis concerns three independent subject areas: the dissipative transport in heterogeneous geological media; a transport problem in an underground gas reservoir; compositional segregation in reservoirs. The common point of all examined problems is the irreversible redistribution of chemical composition of a fluid in the reservoirs. The first chapter is devoted to development of a microscopic model of simultaneous mass and heat transfer in agreement with thermodynamic principles. The second chapter is dedicated to study of multi-component diffusion in a heterogeneous medium. This study aims an application to transport phenomena in hydrocarbon reservoirs characterized firstly by diversity of transported substances (several components + heat) and their interaction (in Onsager’s meaning) and secondly by anisotropy of medium where they take place. The third chapter is dedicated to analytical study of underground gas storage sweeping due to gas dissolution in aquifer. In the fourth chapter the same problem (gas sweeping) was studied numerically in a less idealized approach using finite element method. The fifth chapter is dedicated to study of forced convection taking place in the reservoirs where the temperature gradient and gravity force are not collinear. This convection represents an element of the thermo-gravitational component segregation employed in industry (thermo-gravitational columns) and can take place in underground reservoirs

Full textThis thesis aims at characterizing and understanding acoustic wave propagation in ordered solid foams. We developed a new acoustic probe based on coherent light multiple scattering. This probe called Laser Speckle Visibility Acoustic Spectroscopy is sensitive to the displacement field induced by the acoustic wave in time and space, so that the wave dispersion relation and attenuation can be measured. We validated LSVAS measuring the aforementioned properties in aqueous foams which viscoelastic properties were already known. We then elaborated solid foams with ordered structures by gelling monodisperse liquid foams produced with a microfluidic generator. Generating acoustic waves in a wave guide filled with such a gelled foam, we studied their propagation in a frequency range up to 10 kHz. Longitudinal and transverse wave velocities but also attenuation lengths simultaneously measured at low frequency show that the acoustic wave propagates in solid foam like in an effective viscoelastic continuous medium. Longitudinal and transverse wave velocity variations of this slow mode with gas volume fraction are well described by Wood's law and agree with the semi-empirical law suggested by Ashby & Gibson. At frequencies higher than a few hundred hertz, the transverse wavelength approaches the bubble size and this slow mode is not observed any more. Meanwhile, a much faster mode, which velocity compares to the sound wave velocity in air, appears. We show how this regime and the strong coupling between film and gas displacement in the framework of Biot's acoustic theory
