Key research aspects
Our applied and fundamental research couples different scales in the broad field of reservoir geology. Reservoirs are temporary or permanent, natural or man-made subsurface storage sites. These produce fossil energy and -raw materials, ground heat / geothermal energy, water, and store energy and other substances temporally or permanently.
We establish the anisotropy of the geological bodies and describe the variable rock properties caused by structural, sedimentary, geomagnetic and other geological processes. Outcrops, core from boreholes as well as mines of the quarry and pit industry are studied worldwide.
Rock alteration and associated material- and fluid transport is characterized and modeled using comprehensive analytics and fundamental experiments. The structural diagenesis is quantified from micro- to reservoir scale.
Rock magnetic properties and its anisotropy is studied from sedimentary to basement rocks and is applied on a wide range of geological processes. This ranges from microstructural analyses to stratigraphic correlations.
Our broad experience in the field of rock magnetics contributes to fundamental geological processes and well correlations. We thus contribute to a better understanding of georesources on the earth's surface and subsurface in terms of exploration and production.
Our key aspects are:
Geometry and Heterogeneities of Reservoirs & Quarries
Temporal and spatial changes of rock properties and hydraulic connectivity at reservoir scale, aided by regional 3D-subsurface models and reservoir quaility predictions. Tools: Subsurface data and field analogs and using AgiSoft, ArcGIS, Becip FranLab (FracaFlow), CloudCompare, EasyCore (for teaching), Eclipse, FaroScene, FracPaQ, MatLab, Petrel (incl. Eclipse), PetroMod, TouchStone, WellCad.
Improvement of contact-free analyses of fracture surfaces and mineralogical heterogeneities at quarry wall, cores, tunnels, caves to establish rock qualities and wall stabilities for optimized mining, stability, and a better understanding of 3D heterogeneities. Tools: terrestrial laserscanning, hyperspectral, UAV
Digital models of 3D sedimentary bodies at outcrop scale, fracture networks and porosity-permeability variations in the field as basis for flow simulations. Tools: Laser scanning, image analyses.
Rock Magnetic Properties
We use rock magnetic methods for a lot of different scientific questions:
- Correlation of lithology and magnetic susceptibility
- Determination of the carriers of magnetic properties
- Correlation with geological processes (magmatism, metamorphism, sedimentation) and understanding of geological processes (emplacement mechanisms, fluid-rock-interactions, ect.)
