Lower Jurassic Petroleum System Polygons for Western Canada Basin

Geospatial polygon features delineating the Lower Jurassic petroleum system within the Western Canada Sedimentary Basin. The dataset was created by the Alberta Geological Survey from archived mid-1990s digital files and later edited in 2005-06. It forms part of a reference volume documenting subsurface geology.

Use Cases

• Map the spatial extent of the Lower Jurassic petroleum system using polygon geometry for regional resource assessment.
• Analyze the relationship between petroleum system boundaries and other geological features by joining on spatial location.
• Attribute polygons with properties like formation name or system type for cartographic visualization in GIS software.
• Integrate this petroleum system layer with other subsurface data to model hydrocarbon migration pathways.

Strengths

• Data consolidated into single files by feature type for easier management.
• Polygon features provide specific spatial boundaries for geological analysis.
• Derived from authoritative source, the Alberta Geological Survey.

Limitations

• Original source data was created in the mid-1990s, potentially lacking modern geological interpretations.
• Specific row counts, column names, and attribute details are not provided in the description.
• Limited to a single petroleum system (Lower Jurassic) within the broader basin.
