Thermal Response test (TRT) was carried out at a borehole heat exchanger (well depth: 100 m) at AIST Tohoku to evaluate suitability for Ground-Source Heat Pump (GSHP) System. During the test, an optical fiber sensor was inserted into the U-tube to calculate apparent thermal conductivity by depth. Apparent thermal conductivity of Quaternary were larger than that of Neogene. Apparent thermal conductivity obtained by TRT was compared with thermal conductivity of core samples in Neogene. There is not much difference between them. Quaternary are expected to be more suitable for GSHP system utilizing groundwater flow than Neogene.
