The NSTA Regional Aquifer Presence Maps publication contains a series of geological maps for the UK Continental Shelf, produced by the North Sea Transition Authority. These maps characterize the subsurface geological framework relevant to potential aquifer-based subsurface storage, including CO₂, hydrogen, and compressed air energy storage. The datasets are built upon regional geological interpretations integrating seismic data, well data, and stratigraphic correlation.
Use Cases
- Identify intervals with favourable characteristics for subsurface storage based on Gross Depositional Environment and Lithology attributes.
- Assess regional aquifer presence and continuity for storage potential based on interpreted paleoenvironmental settings.
- Prioritize areas for detailed appraisal based on attributes like Depositional Facies and Chronostratigraphic Age.
Strengths
- Maps are built upon the UKCS Regional Geology Maps project, which integrated seismic interpretation, well data, and field data.
- Attribute information includes multiple geological descriptors such as Gross Depositional Environment, Depositional Facies, and Lithology Group.
- Data is provided in multiple geospatial formats including GEOJSON, KML, GPKG, and an 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.
- Description metadata is limited; actual data quality requires manual inspection after download.
