Applications are welcomed for a PhD position at GeoRessources laboratory, University of Lorraine (France). The PhD project aims at investigating the hydro-mechanical couplings in coalbed methane recovery. Candidates should demonstrate fundamental knowledge of solid and fluid mechanics principles governing the behaviour of porous and fractured media and show motivation for working at the interface between disciplines. An experience in developing numerical methods, particularly DFN/DEM would be an asset.

Applications are welcomed for a PhD position in collaboration between Navier (Ecole des Ponts ParisTech) and LMT (ENS Paris-Saclay) on the hydro-mechanical couplings in clay and cement. The PhD project aims at investigating the elementary mechanisms of water-induced deformations by molecular and meso-scale simulations. Candidates should have a solid background in mechanics and physics of materials with a strong taste for numerical modeling.

In support of the research programme related to the safe disposal of nuclear waste, KU Leuven, SCK•CEN and PSI are looking for a PhD candidate for following topic:
Diffusion of gases in desaturated clay-based materials
The main aim of the PhD is to investigate how desaturation influences the diffusive properties of the samples for gases. This will be accomplished by performing diffusion experiments on different clay-rich materials (e.g. Boom Clay, Opalinus Clay, bentonite, sand-bentonite mixtures, …) at different degrees of saturation (but still highly saturated to avoid a continuous gas pathway), using different gases (He, Ne, CH4, C2H6). Different methods to perform transport experiments under desaturated conditions exist (e.g. osmosis method, saturated salt method …), but none of them has been used to measure diffusivity of dissolved gases. Diffusivity data will be complemented with a full petrophysical characterisation of all samples in order to assess the effect of changing petrophysical properties on diffusivity, and to compare the observations to those of fully saturated samples. The PhD will be executed in the international context of the EC-EURAD project, with close collaboration between SCK-CEN and the Paul Scherrer Institute (PSI, CH) and other partners involved in EURAD.
