3D X-Ray Images of CO2-Acidified Brine Reacting with Limestone Over 2.5 Hours

10 three-dimensional X-ray tomographic images capture the reaction of CO2-acidified brine with Ketton limestone at a 3.8-micron voxel resolution. The British Geological Survey produced this data, imaging the rock during dissolution over a 2.5-hour period. Details are documented in the 2015 journal article 'Menke et al., Environmental Science and Technology'.

Use Cases

• Train segmentation models for pore network extraction based on the masked and cropped segmented images.
• Analyze temporal evolution of dissolution patterns based on the 10 sequential 3D images.
• Validate computational fluid dynamics (CFD) or reactive transport simulations against the experimental image series.
• Develop image processing pipelines for micro-tomography data using the provided raw projections and reconstructed volumes.

Strengths

• Provides 10 sequential 3D images capturing dynamic processes over a 2.5-hour experiment.
• Includes multiple data stages: raw projections (.txrm), reconstructed images (.txm), and segmented images (.am/.raw).
• High-resolution imaging at a consistent 3.8-micron voxel size.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is specific to Ketton limestone, which may limit generalizability to other rock types.
