FIB-SEM and X-ray micro-tomographic images of a wettability-altered carbonate rock sample before and after dissolution with reactive CO2-saturated brine at reservoir pressure and temperature conditions. The data were acquired by the British Geological Survey to investigate CO2 storage in depleted oil fields with oil-wet or mixed-wet conditions. A novel procedure of injecting oil after reactive transport revealed previously unidentified ghost regions of partially-dissolved rock grains.
Use Cases
- Train image segmentation models to identify ghost regions of partially-dissolved rock grains based on the novel experimental procedure described.
- Analyze pore structure evolution for CO2 storage modeling based on before-and-after dissolution images.
- Validate digital rock physics simulations using high-resolution 3D micro-tomographic images acquired under reservoir conditions.
- Study wettability effects on dissolution patterns in carbonate rocks based on the sample's altered wettability state.
Strengths
- Images were acquired under reservoir pressure and temperature conditions, enhancing experimental realism.
- Includes a novel experimental procedure (oil injection post-dissolution) that reveals previously unidentifiable features.
- Data is associated with the British Geological Survey, a recognized authoritative institution.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
