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.

PhD position: Numerical and experimental approaches on the behavior of salt caverns during storage of hydrogen and other gases

PhD opportunity at the École des Mines de Paris – Centre des Géosciences – Fontainebleau

This proposed PhD thesis is dedicated to investigate the integrity of salt cavern mechanical and thermodynamic behavior during fast and slow cycling while addressing the entire complexity of the Computational Fluid Dynamics (CFD) problem, i.e. full discretization of the cavern, gas cavern velocity and thermodynamic variables spatial variations, nature of flow, and the 3D thermo-hydro-mechanical behavior of salt. Moreover, the problem of H2O storage in salt caverns is particular from other gases. This is attributed to the large mobility of hydrogen induced by its very small molecular length, and its potential reactivity with other chemical species that can be present in the storage environment. We aspire that this PhD thesis would shed a light on the phenomenon of hydrogen seepage into the salt rock during fast and slow cycling.

PhD position: Hypoplastic model for unsaturated expansive clays used in simulations of bentonite homogenization for nuclear waste repositories

University: Charles University
Supervisor: David Mašín

Hypoplastic model for unsaturated expansive clays has recently been implemented into an inhouse finite element code SIFEL developed at Czech Technical University. It has been used successfully in simulating behaviour of bentonite buffer in planned nuclear waste repositories.Recently a European framework funded project BEACON has been setup to investigate the process of homogenization of bentonite blocks and pellets to guarantee adequate sealing properties of the buffer. In the proposed project it is planned to both investigate the behaviour of the buffer in laboratory experiments and to numerically model its behaviour.
Laboratory testing will be performed on newly acquired THM unsaturated oedometric apparatus, enabling to perform tests up to 150 °C. Numerical modelling will be done using SIFEL finite element code with hypoplastic constitutive model. The PhD project will thus stimulate both laboratory and numerical skills of the applicant, while he will have a freedom to decide specific orientation of the project depending on his/her interests.

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.

PhD fellowship in rock physics models for improved 4D seismic interpretation

We have a vacancy for a 3 years PhD Fellowship at Department of Geoscience and Petroleum (IGP), NTNU. The work will be a part of the project: Improved prediction of stress and pore-pressure changes in the overburden for infill drilling at SINTEF’s Department of Petroleum, that is supported by the industry and the Research Council. The main objective of this project is to provide calibrated rock-mechanical and rock-physical models for overburden rocks for prediction of stress- and pore-pressure changes in the overburden of a depleting reservoir.
