Taking into account the peculiarities of geological structure and reflection character of aquifers in geophysical fields, the prospecting criteria for ground waters in geological conditions of East Siberia are formed. The structure of prospecting complex includes an airborne geophysical information channels and areal data of electric exploration using near-field time-domain electromagnetic sounding. The important stage of interpretation of geophysics is considered with regard to geological structure, geohydrological conditions and results of structural and geohydrological analysis of the territory.

Keywords: oilfield, ground waters, discharge, structural and geohydrological analysis, airborne geophysics, electric exploration by near-field time-domain electromagnetic sounding, current conduction, induced polarization.
