Well-logs have been used to gain geohydrologic information mainly in Precambrian rocks. The logs used are the self-potential, the diameter, the temperature, and the electric conductivity of water. Applications have given general information on the occurrence of ground water in hard rocks. The logging technique seems to be of particular value in connection with underground constructions in rock when detailed local information is necessary in order to avoid ground water leakage even in minor quantities.
