Lower Jurassic Petroleum System Geospatial Features for Western Canada

Mid-1990s to 2006 geospatial line features representing the Lower Jurassic petroleum system within the Western Canada Sedimentary Basin. This dataset was created by the Alberta Geological Survey, edited in 2005-06, and is part of a geological atlas chapter on petroleum generation and migration. It is published by the Government of Alberta.

Use Cases

• Map petroleum system boundaries and migration fairways using the attributed line features.
• Integrate line features with other subsurface data layers for basin modeling and resource estimation.
• Analyze the spatial relationships of the Lower Jurassic system within the broader Western Canada Sedimentary Basin framework.

Strengths

• Data consolidated and attributed into single files by feature type for consistency.
• Part of a formally published geological atlas chapter, providing authoritative context.

Limitations

• Original digital files were created in the mid-1990s, potentially using outdated methodologies.
• Specific row counts, column details, and spatial accuracy metrics are not provided.
