Lower Mannville Oil and Gas Field Polygons from Geological Atlas

Polygon features map the location and extent of oil and gas fields within the Lower Mannville Group of the Western Canada Sedimentary Basin. This GIS dataset was originally created by the Alberta Geological Survey in the mid-1990s and later edited for accuracy in 2005-2006. It forms part of a reference volume documenting the subsurface geology of the basin.

Use Cases

• Analyze the spatial distribution and density of oil and gas fields using polygon geometry attributes.
• Integrate field polygon data with other geological layers from the Atlas for subsurface modeling.
• Study the historical development of hydrocarbon resources in the Cretaceous Mannville Group based on field boundaries.

Strengths

• Data originates from the authoritative Alberta Geological Survey.
• Polygon features were corrected and attributed during a 2005-2006 consolidation effort.

Limitations

• Underlying source data is from the mid-1990s and may not reflect recent discoveries or field boundary changes.
• Specific column names and attribute details for the polygons are not provided in the description.

Provenance

Collection Method

Produced from archived digital shapefiles, edited to correct and attribute data.

Time Range

Data reflects the geological understanding and field boundaries primarily from the mid-1990s.

Freshness

Last platform update was 2026-03-04, but the core data is historical.
