A series of geological maps from the North Sea Transition Authority characterises the subsurface framework for potential aquifer-based storage. Each map represents a discrete stratigraphic play interval within the UK Continental Shelf, built from integrated seismic, well, and field data. Attribute information includes Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
Use Cases
- Identify intervals with favourable storage characteristics based on lithology group and lithology descriptors.
- Assess regional aquifer presence and continuity based on interpreted paleoenvironmental settings (GDE).
- Prioritise areas for detailed appraisal based on sedimentary facies classification and chronostratigraphic age.
Strengths
- Maps are built upon regional geological interpretations integrating seismic, well, and field data.
- Attribute information includes multiple geological descriptors: Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
- Data is available in multiple geospatial and tabular formats, including GEOJSON, GPKG, and CSV.
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.
