Aquifer Indication of the Leduc Formation, Swan Hills / Slave Point Formations, and Granite Wash in Alberta (gridded data, GeoTIFF format)

This gridded dataset contains aquifer indication grids for the Leduc Formation, the combined Swan Hills and Slave Point formations, and the Granite Wash in Alberta. The grids are a result of analysis and evaluation of water-recovery data from drillstem tests, water flow rates from production and injection wells, and information on hydrocarbon-water contacts and wet wells (water-saturated). For each data source, scoring criteria were established and a score was assigned at each location. Scores from all data sources at each location were merged, and a final aquifer indication score from 1 (low) to 4 (very high) was assigned. The final grids were created by interpolating the final aquifer indication scores derived at each well location and classifying the resulting grids into four aquifer indication classes from 1 (low) to 4 (very high). These grids served as one of the input layers in the weighted analysis for geothermal favourability mapping.

The aquifer indication grids provide a semi-quantitative description of the possibility of aquifer existence rather than quantification. It is a reasonable approximation based on the combined existing information of where the formation has shown it can produce water. Due to the data and information originating mostly from hydrocarbon exploration and development activities, there are biases and limitations associated with this analysis.
