Fractured Bedrock Investigation by Using High-resolution Borehole Images and the Distributed Temperature Sensing Technique


In order to investigate the fracturing of the bedrock and its possible heterogeneous distribution in situ, four boreholes equipped with double-U geothermal pipes of 100 m long were installed on the campus of the University of Liege (Liege, Belgium) over a surface area of 32 m2. The bedrock, which starts at a depth approximately of 8 m, is quite fractured… (More)
