Devonian-Mississippian Petroleum System Polygons For Western Canada Basin

GIS polygon features illustrate the Devonian-Mississippian petroleum system within the Western Canada Sedimentary Basin. Shapefiles were created by the Alberta Geological Survey from mid-1990s digital archives and later edited in 2005-06 for correction and consolidation. The data originates from Chapter 31 of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Delineate petroleum system boundaries and source rock kitchens using polygon geometry features.
• Analyze spatial relationships between geological units for basin modeling based on attributed polygon data.
• Integrate polygon features with other subsurface data layers for regional hydrocarbon potential assessment.

Strengths

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

Limitations

• Original source data is from the mid-1990s, which may not reflect recent geological interpretations.
• Specific row counts, column details, and sample data are unavailable for assessing completeness.
