High resolution study of porosity in clay-rich rocks using Cryogenic Scanning Electron Microscopy and Broad Ion Beam Sectioning We are looking for a candidate with affinity for mineral physics, electron microscopy and image analysis, interested in the study of porous media at nm-scale. The project is in the field of material sciences applied to fine grained rocks containing pore fluid. The project is funded and supported by a major oil company. The successful applicant will study the pore space of claystones in drill cores from sedimentary basins, to develop new models of the grain microstructure and the pore space as the basis for mechanical and transport property modeling. At longer term, the results would be of special interest for producing hydrocarbons from unconventional sources. For this project we will use our new Electron Microscope System. This machine combines cryogenic techniques to vitrify the pore fluids by very fast cooling and excavation of the sample by Ar-beam (BIB, Broad Ion beam) to prepare high quality polished cross-sections for high-resolution imaging (SEM). This allows imaging of pore fluids, pore microstructures and 3D reconstruction of the pore space. The position is open in the Geological of Institute RWTH Aachen University, recently recognized as a centre of excellence in Germany. The successful applicant will work in an international team (http://www.ged.rwth-aachen.de) interested in physical and chemical processes acting in rocks deforming at different scale. We use field, experimental and numerical modeling approaches, and have access to a powerful range of analytical facilities at the RWTH University as well as co-operations with major petroleum companies. Learning German is encouraged but not required. Requirements for the applicant : An M.Sc. or comparable degree in a field related to Material Sciences, Mineral Physics, Geology or Geophysics Background in mineralogy, electron microscopy and/or experimental physics is an advantage Strong interest in the development of innovative methods and applications Proficiency in spoken and written English Motivated, enthusiastic, and participative work outlook to achieve team goals For more information please contact Prof. Dr. Janos Urai, j.urai@ged.rwth-aachen.de, +49 (0)241 80 95723 or Dr. Guillaume Desbois, g.desbois@ged.rwth-aachen.de, +49 (0)241 80 95780.
