Bentheimer Sandstone X-Ray Microtomography Images for Multiphase Flow Analysis

British Geological Survey micro-computed tomography scans of Bentheimer Sandstone during brine and decane coinjection. The dataset includes images from scans at a 6.00µm voxel resolution, capturing fluid distribution at two capillary numbers (3.0E-7 and 7.5E-6) over a range of fractional flows. It was last updated on 2026-04-09.

Use Cases

• Analyzing pore-scale fluid distribution and intermittent occupancy based on differential imaging.
• Modeling relative permeability and fractional flow relationships based on experimental measurements.
• Investigating flow regime transitions (connected vs. breakup) based on capillary number and fractional flow.
• Segmenting and quantifying oil proportion in intermittent phases based on grey scale histogram distributions.

Strengths

• Images acquired at a high resolution of 6.00µm per voxel.
• Experimental data covers two specific capillary numbers (3.0E-7 and 7.5E-6) and a range of fractional flows.
• Includes measured pressure drops and calculated relative permeabilities validated against literature.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
