A series of geological maps from the NSTA Regional Aquifer Presence Maps publication characterize the subsurface framework for aquifer-based storage. The feature classes include attributes for Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age. These datasets were 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 interpreted paleoenvironmental settings.
- Assess regional aquifer presence and continuity based on sedimentary facies and lithology classifications.
- Prioritize areas for detailed appraisal based on the integrated geological maps of the UK Continental Shelf.
Strengths
- Includes multiple geological attribute types: Gross Depositional Environment, Depositional Facies, Lithology Group, and Chronostratigraphic Age.
- Built upon integrated regional interpretations from seismic, well, and field data.
- 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.
