A series of geological maps representing the Middle Jurassic Callovian interval across the UK Continental Shelf, produced by the North Sea Transition Authority. The maps characterize subsurface geology relevant to aquifer-based storage, integrating seismic interpretation, well data, and regional geological understanding. The dataset was last updated on 2026-06-18.
Use Cases
- Identify intervals with favorable storage characteristics based on Gross Depositional Environment and Lithology attributes.
- Assess regional aquifer presence and continuity for subsurface storage potential.
- Prioritize areas for detailed geological appraisal based on interpreted paleoenvironmental settings.
Strengths
- Integrates multiple data sources including seismic interpretation and well data.
- Provides standardized chronostratigraphic age assignments for each interval.
- Available in multiple geospatial formats including GeoJSON and 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.
- Data may reflect geographic bias inherent to the UK Continental Shelf.
