A series of geological maps from the North Sea Transition Authority represent discrete stratigraphic play intervals within the UK Continental Shelf. The maps are built upon regional geological interpretations integrating seismic data, well logs, and field data from the UKCS Regional Geology Maps project. They provide attribute information on Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
Use Cases
- Identify intervals with favourable characteristics for subsurface storage based on interpreted paleoenvironmental setting.
- Assess regional aquifer presence and continuity based on sedimentary facies classification.
- Prioritize areas for detailed appraisal based on simplified lithological descriptors.
- Establish a baseline geological context for storage potential based on chronostratigraphic age assignments.
Strengths
- Maps are built upon integrated regional interpretations from seismic, well, and field data.
- Attribute information includes multiple geological descriptors such as Gross Depositional Environment and Lithology Group.
- Data is provided in multiple geospatial formats including GEOJSON, KML, and GPKG.
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.
Provenance
