Short summary
This study focuses on the assessment of the geothermal potential of two extensive upper Devonian aquifer systems within the Alberta Basin (Canada). Our work provides a first database on geothermal rock properties combined with detailed facies analysis (outcrop and core samples), enabling the identification of preferred zones in the reservoir and thus allowing for a more reliable reservoir prediction. This approach forms the basis for upcoming reservoir studies with a focus on 3-D modelling.
