Nisku Petroleum System Geology of Western Canada Sedimentary Basin

Nisku Petroleum System GIS data consists of polygon features representing petroleum generation and migration zones within the Western Canada Sedimentary Basin. The shapefiles were created by the Alberta Geological Survey from mid-1990s digital files and later edited in 2005-2006. This dataset is part of Chapter 31 of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Map petroleum system boundaries using polygon features to delineate generation and migration zones.
• Analyze spatial relationships between geological units using attributed polygon data from the shapefiles.
• Integrate this GIS layer with other subsurface datasets using its geospatial coordinates for basin-scale studies.

Strengths

• Data originates from the authoritative Alberta Geological Survey.
• Polygon features provide spatially explicit boundaries for geological analysis.

Limitations

• Data is based on digital files from the mid-1990s, making it temporally stale for current dynamics.
• Specific row counts, column details, and sample data are unavailable for assessment.
