The North Sea Transition Authority's Regional Aquifer Presence Maps publication contains a series of geological maps for the UK Continental Shelf. Each map represents a discrete stratigraphic play interval, including the Lower Eocene Lower Ypresian T40, and includes attributes describing Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age. These datasets were built from regional geological interpretations integrating seismic, well, and field data.
Use Cases
- Identify intervals with favourable characteristics for subsurface storage based on interpreted paleoenvironmental settings.
- Assess regional aquifer presence and continuity using sedimentary facies and lithology classifications.
- Prioritize areas for detailed appraisal based on the basin-wide geological framework maps.
Strengths
- Includes multiple attribute layers such as Gross Depositional Environment, Depositional Facies, and Lithology Group.
- Built upon integrated regional interpretations from seismic, well, and field data.
- Available in multiple geospatial formats including GEOJSON, GPKG, and ArcGIS REST API.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
