The structural-tectonic characteristics of the Nepa-Botuoba anteclise are presented, with the oil and gas geological zoning further detailed, also for the Nepa-Botuoba petroliferous area whose oil-gas regions have been identified and characterized, by virtue of substantial geological and geophysical knowledge. Based on the annually updated Information Base for the Quantification of Hydrocarbon Resources of the Lena-Tunguska Petroleum Province (with exception of the Anabar-Khatanga petroleum province, and Lena-Anabar petroleum province), oil-gas regions established within the bounds of the Nepa-Botuoba petroleum province are presented. Their geological (in-place) reserves are estimated, as well as the prepared (category D0), prospective (category D1), including localized (category DL) and inferred, or predicted (category D2) resources of oil and free gas are considered.

Keywords: oil and gas geological zoning, Eastern Siberia, Nepa-Botuoba anteclise, petroleum province, oil-gas region, petroliferous area, petroleum complex, oil/gas fields, reserves and resources, oil, gas.
