A series of geological maps representing discrete stratigraphic intervals within the UK Continental Shelf, produced by the North Sea Transition Authority. The maps characterize the subsurface geological framework for potential aquifer-based storage applications. They are built upon regional interpretations integrating seismic data, well logs, and stratigraphic correlation.
Use Cases
- Identify intervals with favorable storage characteristics based on Gross Depositional Environment and Lithology attributes
- Assess regional aquifer presence and continuity for subsurface storage based on interpreted geological maps
- Prioritize areas for detailed appraisal based on Depositional Facies and Chronostratigraphic Age classifications
Strengths
- Maps are built upon the integrated UKCS Regional Geology Maps project, which used seismic interpretation, well data, and field data
- Each feature class includes multiple attribute layers such as Gross Depositional Environment, Depositional Facies, Lithology Group, and Chronostratigraphic Age
- Data is provided in multiple geospatial formats including GEOJSON, GPKG, and KML for interoperability
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
