Devonian-Mississippian Petroleum System Polygons from Western Canada Basin

Polygon features represent the Devonian-Mississippian petroleum system within the Western Canada Sedimentary Basin. Shapefiles were created by the Alberta Geological Survey in the mid-1990s and edited in 2005-2006. The data is part of Chapter 31 of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Map petroleum system boundaries using polygon geometry features.
• Analyze spatial relationships between hydrocarbon generation zones and other geological units.
• Integrate polygon attributes with other geological layers for basin-scale resource assessment.

Strengths

• Data consolidated into single files by feature type and figure.
• Archived digital files were corrected and attributed during 2005-2006 editing.

Limitations

• Original data created in the mid-1990s, potentially lacking modern geological interpretations.
• Specific polygon attributes and column names are unknown.
• Data scope is limited to a single petroleum system figure from a chapter.
