Temperature Mapping of Select Geological Strata in Alberta (gridded data, ASCII format)

This digital data package contains 15 gridded datasets describing the subsurface (depths >1000 m) temperature distribution at select stratigraphic horizons in Alberta. The grids are the result of data extraction from a 3D model created using culled temperature data from corrected wireline logs, drillstem tests and annual pool pressure surveys and modelled surfaces derived from the Alberta Geological Survey’s Geological Framework of Alberta, Version 3.

Thirteen of the grids represent the temperature distribution at the base of the following geological units (in descending order): the Fernie Formation, Halfway Formation, Doig Formation, Montney Formation, Rundle Group, Exshaw Formation, Wabamun Group, Winterburn Group, Leduc Formation, contiguous Swan Hills and Slave Point formations, Watt Mountain Formation, Sulphur Point Formation, and Keg River Formation. Also included is the temperature grid for the base of the sedimentary succession (represented by the top of the Precambrian), as well as a thermal gradient grid produced by dividing the temperature at the top of the Precambrian, by the depth to the top of the Precambrian.

Information about the methodology used to create the grids is provided in AER/AGS Open File Report 2021-05: Temperature Mapping of Select Devonian Strata in Alberta.
