Middle Devonian Petroleum System Line Features for Western Canada

Geospatial line features from Figure 5 of the Geological Atlas of the Western Canada Sedimentary Basin illustrate the Middle Devonian petroleum system. Shapefiles were created by the Alberta Geological Survey in the mid-1990s and later edited for correction and attribution in 2005-06. The dataset is maintained by the Government of Alberta and was last updated in March 2026.

Use Cases

• Map petroleum system boundaries and migration pathways using line feature geometries.
• Analyze spatial relationships between geological features within the Middle Devonian interval.
• Integrate line features with other atlas layers to model subsurface resource potential.

Strengths

• Data originates from the authoritative Geological Atlas of the Western Canada Sedimentary Basin.
• Features were consolidated and attributed into single files by type in 2005-06.

Limitations

• Original digital files were created in the mid-1990s, so underlying interpretations may be dated.
• Specific row counts, column details, and spatial resolution are not provided.
