The North Sea Transition Authority provides geological maps for the UK Continental Shelf. The dataset characterizes subsurface geological intervals relevant to aquifer-based storage, such as CO₂ or hydrogen storage. It includes interpreted attributes like Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
Use Cases
- Identify intervals with favorable characteristics for subsurface storage based on Gross Depositional Environment and Lithology.
- Assess regional aquifer presence and continuity for storage feasibility studies based on geological maps.
- Prioritize areas for detailed appraisal or data acquisition based on interpreted subsurface variability.
Strengths
- Maps are built upon regional geological interpretations integrating seismic, well, and field data.
- Dataset includes multiple attribute layers such as Gross Depositional Environment, Depositional Facies, and Lithology Group.
- Data is available in numerous formats including XLSX, CSV, GEOJSON, and an ArcGIS GeoServices 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.
