A series of geological maps representing discrete stratigraphic play intervals within the UK Continental Shelf. The feature classes characterize the subsurface geological framework relevant to aquifer-based storage. 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 subsurface storage based on Gross Depositional Environment (GDE) and lithology.
- Assess regional aquifer presence and continuity based on interpreted paleoenvironmental settings.
- Prioritize areas for detailed appraisal based on Depositional Facies and Chronostratigraphic Age classifications.
Strengths
- Maps are built upon the regional geological interpretations from the UKCS Regional Geology Maps project.
- Attribute information includes Gross Depositional Environment, Depositional Facies, Lithology Group, 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.
