Multi-scale heterogeneities in geothermal and unconventional reservoirs from the Zechstein and Muschelkalk of Northern Europe(Late Permian and Middle Triassic): from stratal architecture to pore system networks

This research focuses on multi-scale heterogeneities in geothermal and unconventional reservoirs within the Zechstein and Muschelkalk formations of Northern Germany and other surrounding regions. These carbonate-dominated successions display complex stratal architectures, shaped by regional tectonics, fluctuating sea levels, varying depositional environments and important biosphere changes. High-resolution outcrop and subsurface data are used to characterize facies distribution, stratigraphic discontinuities, and the spatial arrangement of reservoir units.At the pore scale, these studyies integrate petrophysical data, thin-section analysis, and digital rock models to investigate the nature and distribution of pore systems across different diagenetic and depositional domains. Understanding these heterogeneities across scales is essential for improving reservoir quality prediction in both geothermal energy production and unconventional exploration in complex carbonate settings.
