The North Sea Transition Authority provides geological maps for the Upper Paleocene Selandian T20 interval across the UK Continental Shelf. These maps characterize subsurface geology for aquifer-based storage potential, integrating seismic interpretation, well data, and regional geological understanding. The dataset includes attributes for Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
Use Cases
- Screen for favorable subsurface storage intervals based on interpreted Gross Depositional Environment and Lithology.
- Assess regional aquifer presence and continuity based on mapped geological features.
- Prioritize areas for detailed appraisal based on integrated seismic and well data interpretations.
Strengths
- Built upon regional geological interpretations from the UKCS Regional Geology Maps project by Lloyd's Register and the OGA.
- Integrates multiple data sources including seismic interpretation, well data, field data, and stratigraphic correlation.
- Available in multiple geospatial formats including GEOJSON, KML, GPKG, and an ArcGIS 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.
