The NSTA Regional Aquifer Presence Maps publication contains geological maps for discrete stratigraphic intervals on the UK Continental Shelf. These maps characterize subsurface geology relevant to aquifer-based storage like CO₂, hydrogen, and compressed air. The data was produced by Lloyd’s Register and the OGA, integrating seismic interpretation, well data, and regional geological understanding.
Use Cases
- Identify intervals with favorable characteristics for subsurface storage based on Gross Depositional Environment.
- Assess regional aquifer presence and continuity based on interpreted paleoenvironmental settings.
- Prioritize areas for detailed appraisal based on lithology group and facies classification.
Strengths
- Maps are built upon regional geological interpretations integrating seismic, well, and field data.
- Each feature class includes attribute information for Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
- Data is provided in multiple formats including GEOJSON, GPKG, 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.
- Freshness should be verified as the last update is listed as 2026-06-18.
