Current Scientific Projects

  • Development and operation of an underwater georadar device
  • Application of electromagnetically active tracers in the saturated and unsaturated zone for the quantification of flow processes in real time
  • Development and operation of the "i-rock reader" (multi-sensor rock gauge for three-dimensional measurements on cores and arbitrarily shaped, rectangular blocks of rock / slabs
  • Heterogeneity and anisotropy of sub-meter petrophysical parameters (part of Shell's Digital Geology project)
  • Control factors of the "stratigraphic base level" (especially paleoclimate research)
  • Lacustrine sediment distribution systems (littoral)
  • Quantification of specific explosive requirements for different types of rocks
  • Calibration of pXRF devices for specific rock types
  • Climate cycles in cave sediments


  • Digestion analog studies
  • Quantitative 3-D architectural element and lithofacies analysis
  • Petrophysical measuring methods:
    • Porosity
    • Directional apparent and intrinsic permeability
    • Spectral gamma radiation
    • Magnetic susceptibility
    • Resistance measurement techniques (for laboratory and field)
    • Ultrasound velocities
  • Petrology, clay mineral and pore space analysis (quantitative thin-section analysis, semi-quantitative X-ray diffraction (XRD), X-ray fluorescence (XRF) mobile and stationary, scanning electron microscopy)
  • Gocad and Petrel (3-D visualization and interpolation software)
