Particulate Straining in Carbonate Proxy: CT Images and Flow Data

The University of Texas at Austin presents medical CT images and experimental data from particle straining experiments in vuggy proxy media. The dataset includes raw CT scans at 250 micron resolution before and after injection of smaller glass beads, alongside measurements of porosity change, vug surface, permeability over time, and effluent analysis. Experiments cover two flow rates (40 and 60 ml/min) and three flow concentrations (0.5%, 1%, and 2%).

Use Cases

• Modeling particle transport and retention in porous media based on CT-derived porosity changes.
• Analyzing the relationship between flow rate, particle concentration, and permeability reduction based on the described experimental parameters.
• Training image segmentation models to identify vug structures and trapped particles from the before-and-after medical CT images.
• Correlating effluent particle mass measurements with in-situ trapped volume data from CT scans.

Strengths

• Includes paired before-and-after medical CT image sets at 250 micron resolution for direct comparison.
• Experimental conditions are systematically varied across two flow rates and three concentrations.
• Combines multiple data modalities: raw CT images, derived porosity/vug surface measurements, and time-series permeability data.

Limitations

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