The North Sea Transition Authority provides geological maps for the Upper Jurassic Oxfordian interval across the UK Continental Shelf. These maps characterize subsurface geology for potential aquifer-based storage of CO₂, hydrogen, and compressed air. They are based on interpretations from the UKCS Regional Geology Maps project, which integrated seismic, well, and field data.
Use Cases
- Identify intervals with favorable characteristics for subsurface storage based on Gross Depositional Environment and Lithology attributes.
- Assess regional aquifer presence and continuity for storage potential based on interpreted geological maps.
- Prioritize areas for detailed appraisal based on mapped Depositional Facies and Chronostratigraphic Age.
Strengths
- Maps are built upon the regional geological interpretations from the UKCS Regional Geology Maps project.
- Includes attribute information for Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
- Available in multiple geospatial and tabular formats including GEOJSON, GPKG, and CSV.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
