British Geological Survey provides two sets of three-dimensional X-ray micro-tomography images of Ketton carbonate rock cores. The first set is a dry reference scan, and the second set shows the same core after reaction with hydrochloric acid. Each dataset represents a cylindrical core sample 5 mm in diameter and 11 mm in length, scanned at a voxel resolution of 7.97µm using a Versa XRM-500 X-ray Microscope.
Use Cases
- Quantify porosity and pore network changes based on the comparison of dry and acid-reacted 3D images.
- Train 3D image segmentation models to identify mineral phases and void spaces within carbonate rock.
- Simulate fluid flow through rock pores based on the 3D microstructure geometry derived from the scans.
- Analyze the morphological impact of chemical dissolution on carbonate rock based on the reacted core dataset.
Strengths
- Provides a controlled before-and-after comparison with a dry reference scan and an acid-reacted scan.
- High-resolution 3D imaging at a specified 7.97µm voxel resolution.
- Sample dimensions are explicitly stated as 5 mm diameter and 11 mm length.
- Scanned using a specific instrument model (Versa XRM 500 X-ray Microscope).
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file formats are unknown, which may limit suitability assessment.
