The UK Continental Shelf is covered by a series of geological maps from the NSTA Regional Aquifer Presence Maps publication. These maps characterize the subsurface geological framework for potential aquifer-based storage, including CO₂, hydrogen, and compressed air energy storage. The data is built upon regional interpretations by Lloyd’s Register and the OGA, integrating seismic, well, and field data.
Use Cases
- Identify intervals with favorable characteristics for subsurface storage based on Gross Depositional Environment and Lithology.
- Assess regional aquifer presence and continuity based on interpreted paleoenvironmental settings.
- Prioritize areas for detailed appraisal based on Depositional Facies and Chronostratigraphic Age.
Strengths
- Maps are built upon the UKCS Regional Geology Maps project, integrating seismic interpretation, well data, and field data.
- Attribute information includes Gross Depositional Environment, Depositional Facies, Lithology Group, and Chronostratigraphic Age.
- Data is available in multiple geospatial and tabular formats including GEOJSON, GPKG, and CSV.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
