Ordovician Petroleum System Geospatial Features for Western Canada

1990s to 2006 geospatial data representing the Ordovician petroleum system within the Western Canada Sedimentary Basin. The dataset consists of GIS polygon shapefiles created by the Alberta Geological Survey and later edited for correction and consolidation. It documents subsurface geology related to petroleum generation and migration.

Use Cases

• Analyze spatial polygon features to model hydrocarbon generation and migration pathways.
• Map the extent and attributes of the Ordovician petroleum system for basin-scale resource assessment.
• Integrate polygon feature data with other subsurface layers for comprehensive geological modeling.

Strengths

• Data consolidated into single files by feature type for easier analysis.
• Edited in 2005-06 to correct and attribute archived digital files from the mid-1990s.

Limitations

• Original data creation dates to the mid-1990s, potentially lacking modern geological interpretations.
• Specific row counts, column details, and sample data are unavailable for quality assessment.
