High-Resolution Wellbore Temperature Logging Combined with a Borehole-Scale Heat Budget: Conceptual and Analytical Approaches to Characterize Hydraulically Active Fractures and Groundwater Origin

<div>Borehole F3 logging results: (a) televiewing close-up of productive intervals, (b) televiewing log, (c) flow distribution obtained by flowmeter and flow calculated with the heat budget between 14 and 16 m depth, (d) vertical distribution of hydraulic conductivities obtained by flowmeter, and (e) temperature profiles under static and dynamic conditions and temperature of groundwater inflows calculated with the heat budget.</div>
