This polygon dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. This dataset provides the areal distribution of greater than or equal to 0.60 net-to-gross sandstone values for the Paskapoo Formation - Upper Composite Slice, defined by an analysis of normalized oil and gas well digital gamma-ray logs to produce discrete slices of net-to-gross sandstone distribution within the Paskapoo Formation.
The zonated Paskapoo Formation - Middle Composite Slice is in ESRI shapefile format for input into a groundwater flow model.
This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of the steps taken to produce the dataset.
