Obviously, these phenomena are of great interest for the geo-engineering community, as for instance in the framework of mining technologies. Compared to induced hydraulic fractures, NHF do not evolve under an increasing pore pressure resulting from pressing a fracking fluid in the underground but occur and evolve under local pore-pressure reductions resulting in tensile stresses in the rock material. The present contribution concerns the question under what quantitative circumstances NHF emerge and evolve. By this means, the novelty of this article results from the combination of numerical investigations based on the Theory of Porous Media with a tailored experimental protocol applied to saturated porous sandstone cylinders. The numerical investigations include both pre-existing and evolving fractures described by use of an embedded phase-field fracture model. Based on this procedure, representative mechanical and hydraulic loading scenarios are simulated that are in line with experimental investigations on low-permeable sandstone cylinders accomplished in the Porous Media Lab of the University of Stuttgart. The values of two parameters, the hydraulic conductivity of the sandstone and the critical energy release rate of the fracture model, have turned out essential for the occurrence of tensile fractures in the sandstone cores, where the latter is quantitatively estimated by a comparison of experimental and numerical results. This parameter can be taken as reference for further studies of in-situ NHF phenomena and experimental results.", "issn" : "1861-1133", "doi" : "10.1007/s11440-024-02351-7", "bibtexKey": "Wang2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2b2352aa5e52e10e4f591b687a0de7509/simtech", "tags" : [ "EXC2075","PN1","PN1-4","PN1-4(II)","curated" ], "intraHash" : "b2352aa5e52e10e4f591b687a0de7509", "interHash" : "127815b12713770c0896858dcc0184f6", "label" : "Supraglacial lake drainage through gullies and fractures", "user" : "simtech", "description" : "", "date" : "2025-02-07 17:30:06", "changeDate" : "2026-02-16 15:06:37", "count" : 6, "pub-type": "article", "publisher":"Copernicus GmbH", "year": "2024", "url": "http://dx.doi.org/10.5194/egusphere-egu24-16416", "author": [ "Angelika Humbert","Veit Helm","Ole Zeising","Niklas Neckel","Robert Salzano","Giulio Esposito","Matthias Braun","Holger Steeb","Julia Sohn","Matthias Bohnen","Ralf Müller","Martin Rückamp" ], "authors": [ {"first" : "Angelika", "last" : "Humbert"}, {"first" : "Veit", "last" : "Helm"}, {"first" : "Ole", "last" : "Zeising"}, {"first" : "Niklas", "last" : "Neckel"}, {"first" : "Robert", "last" : "Salzano"}, {"first" : "Giulio", "last" : "Esposito"}, {"first" : "Matthias", "last" : "Braun"}, {"first" : "Holger", "last" : "Steeb"}, {"first" : "Julia", "last" : "Sohn"}, {"first" : "Matthias", "last" : "Bohnen"}, {"first" : "Ralf", "last" : "Müller"}, {"first" : "Martin", "last" : "Rückamp"} ], "doi" : "10.5194/egusphere-egu24-16416", "bibtexKey": "Humbert_2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/276c8ddcd8acc53b814a3853e4d061c66/simtech", "tags" : [ "EXC2075","PN1","PN1-4","PN1-4(II)","curated" ], "intraHash" : "76c8ddcd8acc53b814a3853e4d061c66", "interHash" : "f7c904331215eb608e867a91b3e8b572", "label" : "Exploring carbonate rock dissolution dynamics and the influence of rock mineralogy in CO2 injection", "user" : "simtech", "description" : "", "date" : "2025-02-07 17:29:00", "changeDate" : "2026-02-16 15:06:37", "count" : 9, "pub-type": "article", "journal": "Environmental Science & Technology","publisher":"American Chemical Society (ACS)", "year": "2024", "url": "http://dx.doi.org/10.1021/acs.est.3c06758", "author": [ "Javad Shokri","Matthias Ruf","Dongwon Lee","Saleh Mohammadrezaei","Holger Steeb","Vahid Niasar" ], "authors": [ {"first" : "Javad", "last" : "Shokri"}, {"first" : "Matthias", "last" : "Ruf"}, {"first" : "Dongwon", "last" : "Lee"}, {"first" : "Saleh", "last" : "Mohammadrezaei"}, {"first" : "Holger", "last" : "Steeb"}, {"first" : "Vahid", "last" : "Niasar"} ], "volume": "58","number": "6","pages": "2728\u20132738", "issn" : "1520-5851", "doi" : "10.1021/acs.est.3c06758", "bibtexKey": "Shokri_2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/28338cc80241800a30f9566c653fb6346/simtech", "tags" : [ "EXC2075","PN1","PN1-4","PN1-4(II)","curated" ], "intraHash" : "8338cc80241800a30f9566c653fb6346", "interHash" : "c55dcd697f26b06f86ae4697fc1c7f14", "label" : "Data for: Formation of common preferential two-phase displacement pathways in porous media", "user" : "simtech", "description" : "", "date" : "2025-02-07 17:27:02", "changeDate" : "2026-02-16 15:06:37", "count" : 5, "pub-type": "misc", "year": "2024", "url": "", "author": [ "Samaneh Vahid Dastjerdi","Nikolaos Karadimitriou","Holger Steeb" ], "authors": [ {"first" : "Samaneh", "last" : "Vahid Dastjerdi"}, {"first" : "Nikolaos", "last" : "Karadimitriou"}, {"first" : "Holger", "last" : "Steeb"} ], "note": "Related to: Vahid Dastjerdi, S.; Karadimitriou, N.; Hassanizadeh, S.

These snapshots provide real-time information and undergo image processing to derive the required data. Image processing involves several steps tailored to the investigations: Making a reference image (mask): This process involves creating a reference image, or mask, to document the initial conditions. For instance, the porous domain is imaged when saturated with one phase to differentiate various areas containing different phases. Reading and cutting images: Images showing changes in fluid volume fraction are selectively chosen and processed. Each image is read into MATLAB, and the area of interest is extracted. Image segmentation: Labeling each pixel of the images is done via thresholding and edge detection. Measuring parameters: Parameters like saturation, interfacial length, area, contact angle, and curvature are measured. These parameters play a crucial role in analyzing the experiments. The interfacial area is calculated through various formulations. Calculating capillary pressure: Several forms of capillary pressure are calculated using information derived from the experiments. REV-Scale Quantities: Parameters are upscaled to represent Representative Elementary Volume (REV)-scale values essential for continuum theories.

The study is presented in the paper by Karadimitriou et al., 2024. The two fluids were the wetting phase (WP), FluorinertTM, FC-43, and the non-wetting phase (NWP), deionized water mixed with ink, and occasionally with a specific amount of Glycerol. The wetting phase was initially introduced into the pore space of a Poly-Di-Methyl-Siloxane (PDMS) micromodel, fully saturating it. Then, primary drainage scenarios were realized with the introduction of the non-wetting phase under controlled-flux conditions. The objective of the study was to investigate the usability of the fractal dimension of various geometrical entities, like the interfaces between phases, and the bulk non-wetting phase occupancy of the pore space, in the characterization of the flow regime. Main data: The dataset is populated with the raw images acquired during a primary drainage process. Every drainage process took place under a fixed boundary volumetric flux, which is depicted in the title of each file, in terms of the corresponding capillary number. Additionally, the title of each file also includes the viscosity ratio between the invading and the defending phase. A typical file name is in the form Ca=***,M=***.tar. In the images, the non-wetting phase, namely water, shows as dark, and the wetting phase, namely Fluorinert, shows as transparent within the boundaries of the pore network. Flow takes place from right to left. Procedure followed for each constant Ca and M experiment: The term \u201Cexperiment\u201D pertains to the breakthrough of the non-wetting phase from its own inlet to the outlet, at a constant boundary flux. For every experiment, a fixed capillary number value, Cai, i = 1,2,3, is maintained, whereas the viscosity ratio between the invading and the defending phase remains the same through a single experiment. In order for the viscosity ratio to be fixed on demand, Glycerol was added to water at specific concentrations, so as to achieve the desired viscosity of water. The Ca used were 10-2, 10-3, 10-4, and 10-5. The viscosity ratios used were 0.2, 1, and 10. The flow network has overall dimensions of 15 by 20 millimeters, with a mean pore size of 410 microns, and a depth of 100 microns. It is an exact replication of the network used in the work of Sivanesapillai et al., 2018. The micromodel is initially saturated with the wetting phase. Then, the non-wetting phase is injected into the microfluidic pore network. The non-wetting phase is injected at a fixed volumetric flux to maintain a constant value of the capillary number, Ca, during the entire experiment. The wetting phase is getting passively displaced during this process. Even though the experiment, for the needs of the corresponding publication, concludes at breakthrough, some more images are acquired for future purposes.", "affiliation" : "Karadimitriou, Nikolaos/University of Stuttgart, Lee, Dongwon/University of Stuttgart, Vahid Dastjerdi, Samaneh/University of Stuttgart, Steeb, Holger/University of Stuttgart", "orcid-numbers" : "Karadimitriou, Nikolaos/0000-0002-9461-6214, Lee, Dongwon/0000-0003-4826-1632, Vahid Dastjerdi, Samaneh/0000-0003-0315-4067, Steeb, Holger/0000-0001-7602-4920", "doi" : "10.18419/darus-4114", "bibtexKey": "karadimitriou2024primary" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/248d0994b3f91749b53dabdd1299eca13/simtech", "tags" : [ "EXC2075","PN1","PN1-4","PN1-4(II)","curated" ], "intraHash" : "48d0994b3f91749b53dabdd1299eca13", "interHash" : "8b0f05df7202491fd1ae5ffdc41895db", "label" : "Direct and Indirect Measurement of Complex Poisson's Ratio - Direct Measurement in Tension", "user" : "simtech", "description" : "", "date" : "2025-02-07 17:23:20", "changeDate" : "2026-02-16 15:06:37", "count" : 6, "pub-type": "misc", "year": "2024", "url": "", "author": [ "Dominik Fauser","Holger Steeb" ], "authors": [ {"first" : "Dominik", "last" : "Fauser"}, {"first" : "Holger", "last" : "Steeb"} ], "note": "Related to: D.
