Abstract: The application of the methods of borehole geophysicshas diagnostic importance in groundwater studies which includes groundwater investigations, planning, production, production control.Borehole geophysics comprises all geophysical measurements applied in boreholes. The measuring technic of geophysical work, log programing and interpretation in water wellsexhibit distinguished characteristics from those oil and miningborehole geophysics.In the article, the application of borehole geophysical methodshave been outlined in the light of those characteristics.
