This dataset contains the outlines of the evaluated areas for shale- and siltstone-hosted hydrocarbons in Alberta from the Energy Resources Conservation Board/Alberta Geological Survey Open File Report 2012-06. These evaluated areas are for the following units:
- Duvernay Formation,
- Muskwa Formation,
- Montney Formation,
- Basal Banff/Exshaw study area,
- North Nordegg study area, and
- Wilrich Member.
For information on the extent and characteristics of the shale and siltstone units and the overall resource assessment approach see Energy Resources Conservation Board/Alberta Geological Survey Open File Report 2012-06.
To produce the outlines of shale and siltstone units for evaluation, the depositional and erosional extents of the units were modified to only include the areas that are
1. within the borders of Alberta,
2. not within the disturbed belt of the Rocky Mountains, and
3. in the areas where sample data were available.
