| Thermal conductivity measurements have been used for the Way Ratai geothermal prospect area. The thermal conductivity method is used to evaluate the ability of a rock to deliver heat by conduction. In the area, many surface manifestations are scattered in various regions, where hot springs dominate these various manifestations. The thermal conductivity mapping of rocks is carried out around geothermal manifestations by making a hole as deep as 1 m to insert the stick of conductivity meter. The result of thermal conductivity measurement method is data of k (thermal conductivity), Rt (thermal resistivity), and T (temperature). The measured value of conductivity data in the geothermal field is valued between 0.056 and 0.664 W/mK, thermal resistivity between 1.344 and 17.527 mK/W, and the temperature between 22.7 and 52.6°C. The difference in the value of thermal conductivity rock is influenced by several factors: existing geological structures in the field such as normal faults and lineaments, presence of alteration, and the manifestation zone of hot water or hot vapor that caused by fumaroles. | ||
