PhD Position on Multi-scale hydro-mechanical modeling of coalbed methane recovery at the University of Lorraine, France

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.

Postdoctoral position: Effect of Microstructural factors on deformation and fluid transport in partially saturated low permeability materials

The topic deals with the investigation of the mecanisms of deformation at
different fluid interfaces at the microstructure scale of low permeability
materials. In particular, it focuses on the experimental identification of
quantitative interactions between the microstructure, the fluid flow and the deformation of low permeability clayey materials.

Duration : 1 year + 1 year
September 2019 to August 2021

Opening position for a Researcher: Numerical modelling in geotechnics

Job description: The successful candidate will develop research in numerical modelling of soil-structure interaction under complex loadings including dynamics. Fundamental and numerical studies will be developed in relation with experimental studies performed in Laboratoire Navier and by outside partners. In addition to the development of classical techniques for numerical modelling of materials and structures (FEM, BEM, FFT, …), the valorization of big data gathered from the monitoring of geotechnical structures will be a priority area of research. This includes the development of new tools based on artificial intelligence systems for modelling and design in geotechnics.

These research activities will make use of advanced numerical methods and will be oriented towards applications to underground structures, foundation engineering, resilience of geotechnical structures, effect of multiphysics couplings on the behavior of geomaterials (partial saturation, thermal effects, …).

The selected researcher will show a strong commitment in developing industrial partnerships and in setting up European and national research projects. He will also participate to consultant and expert activities in geotechnics.

Predicting foundation response for offshore wind turbines Supervised by Britta Bienen, Conleth O’Loughlin

The aim of this research is to predict the installation and in service response of suction buckets supporting offshore wind turbines. This foundation concept is now being adopted in offshore wind farm designs. Following self-weight penetration into the seabed, the bucket is installed by pumping water out of the bucket, which creates a pressure differential across the lid and drives further penetration. In service, the foundation needs to resist the cyclic loading imposed on the turbine from the ocean environment. The mechanisms of suction installation (in layered soils in particular) and the effects of the installation process on the soil state are poorly understood. The evolution of foundation stiffness and displacement underpin the design. The research will be predominantly experimental, utilising recently developed purposedesigned experimental facilities. The project is a collaboration with Lloyd’s Register EMA and Melbourne University.

PhD position at the Catholic University of Leuven, Belgian Nuclear Research Center and Paul Scherrer Institute

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.
