We analyze geologic and geophysical factors enhancing the prerequisites for the high petroleum potential of East Siberia that were formulated by A.A. Trofimuk in 1960. The main updates concern the northern Siberian Platform, where it is indeed possible to significantly increase its petroleum potential and to refine the localization of large and giant, mostly oil accumulations.

We analyze new geologic and geophysical data, which confirm Trofimuk’s (1960) high evaluation of the petroleum potential of the Silurian–Devonian sediments in the northwestern Siberian Platform. Priority targets are set for geologic exploration aimed at testing his scientific predictions.
