The NSTA Regional Aquifer Presence Maps publication contains geological maps for discrete stratigraphic intervals on the UK Continental Shelf. The feature classes characterize the subsurface geological framework for potential aquifer-based storage of CO₂, hydrogen, and compressed air. These datasets were built by Lloyd’s Register and the OGA, integrating seismic interpretation, well data, and regional geological understanding.
Use Cases
- Identify intervals with favorable characteristics for CO₂ storage based on Gross Depositional Environment and Lithology attributes.
- Assess regional aquifer presence and continuity for hydrogen storage based on interpreted paleoenvironmental settings.
- Prioritize areas for detailed appraisal of compressed air energy storage potential 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.
- 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.
- Description metadata is limited; actual data quality requires manual inspection after download.
