The NSTA Regional Aquifer Presence Maps publication contains a series of geological maps for the UK Continental Shelf. Each map represents a discrete stratigraphic play interval and includes attributes describing Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age. The datasets were produced by Lloyd’s Register and the OGA, integrating seismic interpretation, well data, and regional geological understanding.
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.
- Prioritize areas for detailed appraisal based on geological context and facies classification.
Strengths
- Maps are built upon integrated regional interpretations from seismic, well, and field data.
- Each feature class includes attribute information for Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
- Data is available 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 dated 2026-06-18.
