Middle Devonian Petroleum System Polygons From Western Canada Sedimentary Basin

Geospatial polygon features represent the Middle Devonian petroleum system within the Western Canada Sedimentary Basin. The data was originally created by the Alberta Geological Survey in the mid-1990s and later edited and attributed in 2005-06. It is part of a geological atlas chapter on petroleum generation and migration.

Use Cases

• Analyze the spatial extent of the Middle Devonian petroleum system using polygon boundaries. Model hydrocarbon migration pathways based on attributed geological features within the shapefiles. Integrate polygon features with other subsurface data layers for basin-scale resource evaluation.

Strengths

• Data consolidated into single files by feature type for easier analysis
• Polygon features were corrected and attributed during a dedicated 2005-06 editing process

Limitations

• Original data creation dates to the mid-1990s, which may not reflect recent geological interpretations
• Specific row counts and attribute column details are not provided
