Alberta Subsurface Geological and Hydrostratigraphic Grids

This collection comprises gridded elevation, thickness, and extent models for key geological formations and aquifers in Alberta, such as the Paskapoo, McMurray, and Empress Formations, and the Sunchild Aquifer. The data provides the foundational structural surfaces necessary for three-dimensional subsurface modeling. These standardized grids support integrated workflows in hydrogeology and petroleum geology, allowing for the analysis of groundwater flow paths, aquifer storage potential, and hydrocarbon reservoir geometry within a consistent spatial framework.
