Nisku Petroleum System Geospatial Overlay Features

Shapefile data maps the Nisku Petroleum System, a key hydrocarbon generation and migration zone within the Western Canada Sedimentary Basin. The files were originally created by the Alberta Geological Survey in the mid-1990s and later edited for correction and consolidation between 2005 and 2006. This dataset is part of a published geological atlas chapter.

Use Cases

• Analyze petroleum system polygon boundaries to model hydrocarbon migration pathways.
• Overlay Nisku system features with other geological shapefiles from the atlas for basin-scale analysis.
• Use GIS attribute data to assess the spatial extent of hydrocarbon generation zones.
• Integrate polygon overlay features into subsurface models for resource estimation.

Strengths

• Data originates from the authoritative Alberta Geological Survey.
• Represents a specific, documented petroleum system (Nisku) from a published atlas chapter.
• Data was edited and consolidated into single files by feature type in 2005-06.

Limitations

• Data is based on mid-1990s source files, potentially lacking modern geological insights.
• Specific row counts, column attributes, and spatial resolution are unknown.
• Limited to a single petroleum system within the larger Western Canada Sedimentary Basin.
