Abstract
The paper presents new software and stepwise modeling techniques for inversion of TEM data affected by fast-decaying induced polarization (IP). The software and the methods have demonstrated high efficiency when applied to detection of unfrozen ground zones (taliks) in the Pyakyakhinka oilfield and to petroleum exploration in the southern Siberian craton.
