In this paper different aspects of desirable conditions In shallow weIl logging and various corrections that one must employ to provide a good picture of geological structures for important engineering purposes like dam constructions is presented. To examine the proposed corrections electrical weIl logging data of Salman Dam site were chosen. The dam site area was located in south central part of Zagros mountain ranges, Shiraz, Iran. In this project, nine boreholes and totally six thousand meters of weIl logging experiment including temperature, normal, sp, natural gamma, caliper, gamma-gamma and a case of fluid resistivity testing were logged. The results revealed temperature anomaly of about 5C, presence of low resistivity layers, under ground hot water flow and a minor fault impression,
