X-Ray Micro-Tomography Images of Fluid Flow in Estaillades Carbonate

X-ray micro-tomography images capture the steady-state flow of brine and decane in a micro-porous limestone sample during dual injection. The dataset was created by the British Geological Survey and last updated in April 2026. It includes measurements of fluid phase occupancy and relative permeability at a capillary number of 7.3×10^-6.

Use Cases

• Modeling relative permeability in carbonate rocks based on the measured fluid phase occupancy.
• Analyzing flow intermittency patterns based on the identification of an intermittent phase in the macroscopic pore space.
• Classifying fluid occupancy in micro-porosity based on the three described sub-phases: oil-filled, brine-filled, and partially filled.

Strengths

• Sample porosity is quantified at approximately 28%, with a breakdown of 7% macro-pores and 21% micro-pores.
• Measurements were taken at a specific, stated capillary number (Ca = 7.3×10^-6).
• The description provides a detailed classification of fluid occupancy in both macro and micro-porosity.

Limitations

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