Oil Alteration Features in the Western Canada Sedimentary Basin

Mid-1990s digital files from the Alberta Geological Survey were edited and consolidated into a single GIS shapefile collection by 2006. This dataset represents line features depicting oil alteration processes as part of a geological atlas chapter on petroleum generation and migration. It was published by the Government of Alberta and updated on the open_canada platform in March 2026.

Use Cases

• Analyze the spatial distribution of oil alteration line features relative to known geological structures.
• Integrate oil alteration features with other subsurface data layers to model petroleum systems.
• Use the geospatial line features to validate or calibrate basin-scale hydrocarbon generation models.

Strengths

• Data consolidated from archived files into single files by feature type.
• Geospatial features are attributed, indicating structured data enrichment.

Limitations

• Original data was created in the mid-1990s, potentially limiting modern analytical relevance.
• Specific row counts, column details, and sample data are unavailable for assessment.
• Data may contain legacy inaccuracies corrected only up to 2006.
