Devonian Petroleum System Polygons for Western Canada Basin

Geospatial polygon features map the Devonian petroleum system within the Western Canada Sedimentary Basin. The data was created by the Alberta Geological Survey in the mid-1990s and later edited in 2005-06. It originates from a chapter of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Model hydrocarbon migration pathways using polygon boundaries and associated geological attributes.
• Analyze the spatial relationship between the Devonian system and other geological features from the Atlas.
• Integrate polygon features with well data to assess petroleum potential in specific regions.
• Use the attributed shapefiles for basin-scale geological mapping and reference.

Strengths

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

Limitations

• Original data creation dates to the mid-1990s, potentially lacking modern discoveries.
• Specific row counts, column details, and spatial resolution are not provided.
