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 PO-7 logging results: (a) televiewing close-up of the most productive fracture, (b) televiewing log, (c) flow distribution obtained by flowmeter, (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>
