A series of geological maps from the North Sea Transition Authority characterizes the subsurface framework for potential aquifer-based storage. These maps integrate seismic interpretation, well data, and regional geology to depict stratigraphic play intervals. Each feature class includes attributes for depositional environment, facies, lithology, and chronostratigraphic age.
Use Cases
- Identify intervals with favorable characteristics for subsurface storage based on Gross Depositional Environment and Lithology attributes.
- Assess regional aquifer presence and continuity for storage potential based on interpreted geological maps.
- Prioritize areas for detailed appraisal or data acquisition based on mapped geological variability.
Strengths
- Maps are built upon the UKCS Regional Geology Maps project, integrating seismic interpretation, well data, and field data.
- Feature classes include multiple geological attributes: Gross Depositional Environment, Depositional Facies, Lithology Group, Lithology, and Chronostratigraphic Age.
- Data is provided in multiple geospatial and tabular formats including GEOJSON, GPKG, CSV, and XLSX.
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.
Provenance
- Source
- North Sea Transition Authority
- Collection Method
- Built upon regional geological interpretations from the UKCS Regional Geology Maps project by Lloyd’s Register and the OGA, integrating seismic, well, and field data.
