A series of geological maps from the NSTA Regional Aquifer Presence Maps publication represent discrete stratigraphic play intervals. The feature classes characterize the subsurface geological framework for potential aquifer-based storage, including CO₂, hydrogen, and compressed air. These datasets are built upon regional interpretations by Lloyd’s Register and the OGA, integrating seismic, well, and field data.
Use Cases
- Identify intervals with favorable characteristics for subsurface storage based on Gross Depositional Environment and Lithology.
- Assess regional aquifer presence, continuity, and variability based on interpreted paleoenvironmental settings.
- Prioritize areas for detailed appraisal based on Depositional Facies and Chronostratigraphic Age.
Strengths
- Maps are built upon integrated regional interpretations from the UKCS Regional Geology Maps project.
- Feature classes include attribute information for Gross Depositional Environment, Depositional Facies, Lithology, and Chronostratigraphic Age.
- Data is available in multiple formats including GEOJSON, GPKG, and an ArcGIS GeoServices REST API.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
Provenance
- Source
