Residual Air in Air/Brine Systems: Pore-Scale Images of Three Geological Samples

Raw X-ray computed microtomography images of residual gas in three pore structures: a glass bead pack, a Boise sandstone, and a Fontainebleau sandstone. The data were acquired at the Beamline 8.3.2 at the Advanced Light Source, Lawrence Berkeley National Laboratory, with voxel sizes ranging from 4.44 µm to 0.64 µm.

Use Cases

• Measure gas ganglia capillary pressures based on air/brine interfacial curvature measurements.
• Analyze pore structure and fluid distribution in geological samples based on the three imaged materials.
• Validate pore-scale simulation models based on the raw images of air and brine after gravity-driven imbibition.

Strengths

• Images were acquired at a synchrotron facility (Beamline 8.3.2, Advanced Light Source), suggesting high-quality instrumentation.
• Data includes three distinct pore structures (glass bead pack, Boise sandstone, Fontainebleau sandstone) for comparative analysis.
• Multiple imaging resolutions (2X - 4X/5X - 10X) provide voxel sizes from 4.44 µm to 0.64 µm.

Limitations

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