Cretaceous Second White Specks Petroleum System Line Features

Geospatial line features represent the Cretaceous Second White Specks petroleum system within the Western Canada Sedimentary Basin. The dataset was created by the Alberta Geological Survey in the mid-1990s and later edited in 2005-06 for correction and consolidation. It is part of a reference volume documenting subsurface geology.

Use Cases

• Model petroleum migration pathways using the attributed line features representing system boundaries.
• Integrate these line features with other geological shapefiles from the Atlas for basin-scale analysis.
• Analyze the spatial relationship of the Second White Specks system to other petroleum systems in the basin.
• Use the GIS data to visualize the extent and geometry of this specific Cretaceous hydrocarbon system.

Strengths

• Data is part of an authoritative Geological Atlas reference volume.
• Shapefiles were consolidated and attributed during a dedicated 2005-06 editing process.

Limitations

• The original digital files were created in the mid-1990s, potentially using outdated methods.
• Specific row counts, column attributes, and spatial resolution are not provided.
