This study of the Devonian Leduc and Grosmont formations along the northeastern extension of the Rimbey-Meadowbrook Reef supplies the basic geological framework for a reservoir modelling study to appraise the feasibility of using the Leduc to concurrently source and dispose water. Deliverables include subcrop, isopach and structure maps, structural cross-sections, core analysis (five wells), petrophysical analysis (nine wells), core porosity/permeability crossplots, core photographs and a hydrological summary of the Leduc aquifer.
