Hydrology Research, 1972 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.
