EPSRC Grant EP/L012227/1: 3D Images of Estaillades Carbonate for Flow Simulation

A 2015 study investigated pore-scale heterogeneity effects on non-Darcy flow using direct flow simulations on 3-D images of Estaillades carbonate. The dataset, associated with EPSRC grant EP/L012227/1, is hosted by the British Geological Survey and also available via the Digital Rocks Portal. The research compared flow regimes in Estaillades carbonate to Bentheimer sandstone and beadpack, finding a significantly lower critical Reynolds number for the transition from Darcy flow.

Use Cases

• Simulating non-Darcy flow behavior based on 3D pore structure images
• Comparing critical Reynolds numbers across different porous media types (carbonate, sandstone, beadpack) as described
• Investigating the formation of steady eddies in pore spaces at elevated fluid velocities
• Validating theoretical models for reactive transport in subsurface porous media

Strengths

• Dataset is linked to a peer-reviewed publication in Advances in Water Resources (2015).
• Data is hosted on the authoritative Digital Rocks Portal with a DOI (10.17612/P73W2C).
• Research provides a direct comparison of flow behavior across three distinct porous media types.

Limitations

• Column-level documentation and sample data are unavailable, requiring field semantics to be inferred after download.
• The dataset's scale (number of images, rows) is unknown, which may limit suitability assessment.
• Last updated metadata indicates 2026-04-09; freshness should be verified as the underlying research is from 2015.
