Lower Jurassic Petroleum System Geospatial Features in Western Canada

Shapefile data delineates the Lower Jurassic petroleum system within the Western Canada Sedimentary Basin. The Alberta Geological Survey created the original digital files in the mid-1990s, with subsequent edits in 2005-06 for correction and consolidation. This dataset represents Figure 19 from a chapter on petroleum generation and migration in the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Map petroleum system boundaries and migration pathways using line features.
• Integrate system outlines with other subsurface geological layers for basin analysis.
• Analyze the spatial relationship of the Lower Jurassic system to other geological features in the basin.

Strengths

• Data consolidated from archived sources into single files by feature type.
• Edited to correct and attribute data, improving usability.

Limitations

• Original data creation dates to the mid-1990s, potentially lacking modern discoveries.
• Unknown row count and specific attribute details for line features.
