A series of geological maps from the NSTA Regional Aquifer Presence Maps publication characterises the subsurface geological framework of the UK Continental Shelf. The datasets are built upon regional geological interpretations from the UKCS Regional Geology Maps project, which integrated seismic interpretation, well data, and stratigraphic correlation. These maps provide a baseline understanding of geological context for potential aquifer-based subsurface storage, including CO₂, hydrogen, and compressed air.
Use Cases
- Identify intervals with favourable characteristics for subsurface storage based on Gross Depositional Environment and Lithology.
- Assess regional aquifer presence and continuity based on interpreted paleoenvironmental settings.
- Prioritise areas for detailed appraisal based on 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 attribute layers such as 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.
