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

Abstract

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)
