A series of geological maps from the North Sea Transition Authority represent discrete stratigraphic play intervals within the UK Continental Shelf. The feature classes characterize the subsurface geological framework relevant to potential aquifer-based storage, including CO₂, hydrogen, and compressed air. These datasets are built upon regional interpretations integrating seismic data, well logs, and field observations.
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 paleoenvironmental settings.
- Prioritize areas for detailed geological appraisal based on attributes like Depositional Facies and Chronostratigraphic Age.
Strengths
- Maps are built upon the integrated UKCS Regional Geology Maps project, which used seismic interpretation, well data, and field data.
- Feature classes include multiple geological attributes: Gross Depositional Environment, Depositional Facies, Lithology Group, and Chronostratigraphic Age.
- Data is provided 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.
- The maps are described as an early-stage screening tool, not a substitute for detailed geological modelling.
