The North Sea Transition Authority provides geological maps for the Middle Jurassic Bathonian interval across the UK Continental Shelf. The dataset characterizes subsurface geological features relevant for aquifer-based storage of CO₂, hydrogen, and compressed air. It was last updated on 2026-06-18.
Use Cases
- Screen for subsurface storage intervals based on interpreted Gross Depositional Environment (GDE).
- Assess regional aquifer continuity and variability based on Depositional Facies classification.
- Prioritize areas for detailed appraisal based on mapped Lithology Group and Lithology.
- Correlate geological intervals across the basin using standardised Chronostratigraphic Age assignments.
Strengths
- Dataset integrates seismic interpretation, well data, field data, and stratigraphic correlation.
- Maps are built upon regional geological interpretations from the UKCS Regional Geology Maps project.
- Data is provided in multiple formats including GEOJSON, GPKG, and ArcGIS REST API.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
