S1 Sandstone: Micro-CT Image and Extracted Pore Networks

S1 sandstone is a micro-CT image dataset with extracted pore networks, published by Dong and Blunt in 2009. The data is provided by the Imperial College Consortium On Pore-Scale Modelling and includes a header file for visualization in software like Paraview or ImageJ. The dataset is openly accessible under an Open Access (green) license.

Use Cases

• Visualizing 3D pore structure based on the provided micro-CT image file.
• Simulating fluid flow in porous media based on the extracted network data.
• Validating pore network extraction algorithms against a known sandstone sample.
• Conducting morphological analysis of geological samples using the image data.

Strengths

• Dataset is associated with a peer-reviewed publication (DOI: http://dx.doi.org/10.1103/PhysRevE.80.036307).
• Includes both raw micro-CT image data and derived network data, enabling multi-stage analysis.
• Data is openly accessible under an Open Access (green) license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
