Thus, temperature-depth profiles can be measured by distributed fiber optic temperature measurements at any required time. By applying an electrical heating voltage, the cable is heated over its. An EGRT is used for the depth-dependent determination of thermal soil parameters, such as thermal conductivity and borehole resistance. This initiative focuses on harnessing geothermal energy through the drilling of two horizontal wells, which have been stimulated using hydraulic fracturing techniques. The continuous heating cable with a low power source is a promising method to perform thermal response tests and further tests could be carried out in deep boreholes to verify its applicability.
