Project Z02 (Porous Media Lab) provides experimental infrastructure and expertise for studying flow, transport, and deformation in porous media. It supports CRC 1313 with microfluidics and in-situ XRCT, enabling high-resolution, real-time imaging. Key advances include custom micromodels, novel imaging setups, and 4D data tools. Research addressed fracture mechanics, salt precipitation, and carbonate dissolution. Upcoming goals focus on dynamic fatigue tests, spectral XRCT, and tracer-based microfluidic analysis. The lab drives benchmarking and validation efforts across the CRC. Strong collaborations amplify its scientific and technical impact.

Digital rock physics: A geological driven workflow for the segmentation of anisotropic Ruhr sandstone: micro-XRCT data set
May 4, 2021 - Publication: Digital rock physics: A geological driven workflow for the segmentation of anisotropic Ruhr sandstone
Ruf, Matthias; Balcewicz, Martin; Saenger, Erik H.; Steeb, Holger, 2021, "Digital rock physics: A geological driven workflow for the segmentation of anisotropic Ruhr sandstone: micro-XRCT data set", https://doi.org/10.18419/DARUS-1152, DaRUS, V1
The Ruhr sandstone is assigned to the Upper Carboniferous and is part of the Ruhr cyclothem located in North Rhine-Westphalia, which consists of clays, siltstones, mudstones, sandstones, and interbedded coal seams. The sediment was chemically and mechanically compacted, folded, and faulted during the Hercynian orogeny. The studied microstructure of...
