Middle Triassic Petroleum System Polygons for Western Canada

1990s to 2006 geospatial polygon features representing the petroleum system of the Middle Triassic period within the Western Canada Sedimentary Basin. This dataset was created by the Alberta Geological Survey and later edited for correction and consolidation. It originates from Chapter 31 of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Analyze the spatial extent and boundaries of the Middle Triassic petroleum system using polygon geometry features.
• Integrate polygon attributes with other geological layers to model hydrocarbon migration pathways.
• Assess the resource potential of the sedimentary basin by overlaying these system polygons with well or seismic data.

Strengths

• Data consolidated from archived files into single files by feature type, improving usability.
• Polygon features provide a defined spatial representation of a complete petroleum system.

Limitations

• Original data created in the mid-1990s, potentially lacking modern geological interpretations.
• Specific sample size, row count, and attribute details for the polygons are unknown.
