A geological map feature class from the North Sea Transition Authority's Regional Aquifer Presence Maps publication. The dataset characterizes the subsurface geological framework for the Upper Paleocene Selandian T20 interval across the UK Continental Shelf. It is built upon regional interpretations integrating seismic data, well logs, and stratigraphic correlation.
Use Cases
- Identify intervals with favorable characteristics for subsurface storage based on Gross Depositional Environment and Lithology attributes.
- Assess regional aquifer presence and continuity based on interpreted paleoenvironmental and facies data.
- Prioritize areas for detailed geological appraisal or data acquisition based on mapped stratigraphic intervals.
Strengths
- Based on the UKCS Regional Geology Maps project integrating seismic interpretation, well data, and field data.
- Includes multiple geological attribute layers such as Gross Depositional Environment, Depositional Facies, and Lithology.
- Available in multiple geospatial and tabular formats including GEOJSON, GPKG, and CSV.
Limitations
- Row count and dataset size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
