A series of geological maps representing discrete stratigraphic play intervals within the UK Continental Shelf. The feature classes characterize the subsurface geological framework relevant to potential aquifer-based subsurface storage, including CO₂, hydrogen, and compressed air. The datasets are built upon regional geological interpretations from the UKCS Regional Geology Maps project, integrating seismic, well, and field data.
Use Cases
- Identify intervals with favourable or unfavourable characteristics for subsurface storage based on Gross Depositional Environment and Lithology.
- Assess regional aquifer presence, continuity, and variability using interpreted paleoenvironmental settings.
- Prioritize areas for detailed appraisal or data acquisition based on sedimentary facies classification and chronostratigraphic age.
Strengths
- Based on the UKCS Regional Geology Maps project integrating seismic interpretation, well data, field data, and stratigraphic correlation.
- Includes attribute information for Gross Depositional Environment, Depositional Facies, Lithology Group, Lithology, and Chronostratigraphic Age.
- Available in multiple geospatial and tabular formats including GEOJSON, GPKG, CSV, and XLSX.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
