Duvernay Interval Isopach and Lithofacies GIS Data for Western Canada Sedimentary Basin

The Duvernay Interval Isopach and Lithofacies dataset is a GIS shapefile collection representing subsurface geology from the Geological Atlas of the Western Canada Sedimentary Basin. It contains polygon features illustrating rock layer thickness and composition for the Devonian Woodbend-Winterburn strata. The Alberta Geological Survey created the original digital files in the mid-1990s, which were later edited and consolidated in 2005-2006.

Use Cases

• Map spatial variations in rock layer thickness using isopach polygon features.
• Analyze the distribution of different rock types using lithofacies polygon attributes.
• Integrate polygon data with other subsurface datasets for basin-scale geological modeling.
• Study Devonian-age Woodbend-Winterburn strata for hydrocarbon resource assessment.

Strengths

• Data is part of the authoritative Geological Atlas of the Western Canada Sedimentary Basin.
• Polygon features were corrected, attributed, and consolidated into single files in 2005-2006.

Limitations

• Original source data was created in the mid-1990s, potentially limiting modern analytical precision.
• Specific row counts, column details, and sample data are unavailable for assessment.
• Data scope is limited to a single figure (Figure 17) from a specific atlas chapter.
