Core Flood CT Scans of Three Heterogeneous Carbonate Rocks

Medical CT scans from drainage multiphase flow experiments on three heterogeneous carbonate rocks: Indiana limestone, Estaillades limestone, and Edwards dolomite. The dataset contains CT scans under dry conditions, with nitrogen, with water, and at varying nitrogen fractional flow rates, alongside a readme and an Excel file. Data originates from three quarries in the USA and France, collected for the ACT ELEGANCY project.

Use Cases

• Analyze CT scans at varying nitrogen fractional flow rates to model multiphase flow dynamics in carbonate rocks.
• Characterize the impact of rock heterogeneity on residual trapping by comparing scans from Indiana limestone, Estaillades limestone, and Edwards dolomite.
• Use medical CT Dry scans, nitrogen scans, and water scans to calibrate digital rock physics models for carbon storage applications.

Strengths

• Includes CT scans from three distinct carbonate rock types, enabling comparative analysis of heterogeneity.
• Scans capture multiple experimental states: dry, nitrogen-saturated, water-saturated, and varying fractional flows.
• Data is associated with a specific research grant (ACT ELEGANCY, Project No 271498) and organization (British Geological Survey).

Limitations

• The dataset structure is unclear; it consists of 27 zip files, one Excel file, and one readme without a defined tabular schema.
• Sample size and temporal coverage are unspecified, limiting statistical power and trend analysis.
• Potential geographic bias as samples are from only three specific quarry locations in the USA and France.
