Geothermal Favourability of the Leduc Formation, Swan Hills / Slave Point Formations, and Granite Wash in Alberta Using Geological Criteria (gridded data, GeoTIFF format)

This digital data package contains 12 gridded datasets describing four scenarios of geothermal favourability based on geological criteria for three geological units: the Leduc Formation, combined Swan Hills and Slave Point formations, and the Granite Wash. The geothermal favourability grids were created using the GIS-weighted overlay method, utilizing "Temperature," "Aquifer Indication," and "Porosity Thickness" as input grids. Different weights were assigned to each grid in every scenario:

Scenario 1 Temperature – 50%, aquifer indication – 30%, and porosity thickness (PHI*H) – 20%
Scenario 2 Temperature – 70%, aquifer indication – 20%, and porosity thickness (PHI*H) – 10%
Scenario 3 Temperature – 45%, aquifer indication – 10%, and porosity thickness (PHI*H) – 45%
Scenario 4 Temperature – 45%, aquifer indication – 45%, and porosity thickness (PHI*H) – 10%

The extent of the geothermal favourability grids is determined by the convergence of all three input grids. Consequently, if any one of these grids is absent in a particular area, the favourability prediction for geothermal potential will not be available for that area. The geothermal favourability grid was classified into four favourability classes from 1 (low) to 4 (very high).
