The Lena-Tunguska petroleum province lies within the ancient craton of the Siberian platform and occupies an area of 2,570,000 km{sup 2}. It includes the Anabar, Baikit, Nepa-Botuoba, Aldan anteclises, Turukhan-Norilsk uplift, Angara-Lena step, Kureika, Pre-Sayany-Yenisei syneclises, and Predpatomskii regional trough. The sedimentary cover of the Lena-Tunguska province is divided into the following large petroleum-bearing complexes: Riphean, Vendian, upper Vendian-Lower Cambrian, Cambrian, Ordovician-Devonian, and Carbonaceous-Triassic complexes. More than 80% of initial oil gas resources are found in the upper Proterozoic and Lower Cambrian. The main source rocks are confined to the Riphean, Vendian, and Cambrian. Five percent of hydrocarbon resources are converted into reserves. The province is divided into twelve petroleum-bearing regions; North Tunguska, South Tunguska, Baikit, Katanga, Pre-Sayany-Yenisei, Angara-Lena, Nepa Botuoba, Predpatoma, Syugdzhersk, Anabar, West Vilyui, and North Aldan regions, and Turukhan-Norilsk individual petroliferous area. Oil and gas pools in the Riphean complex are in the Baikit and Predpatoma petroliferous regions. The Vendian petroliferous complex is commercially important in the Baikit, Katanga, Angara-Lena, Nepa, Botuoba, and Predpatoma petroliferous regions. In the Vendian-Cambrian petroliferous complex oil, oil and gas and gas pools are in the South Tunguska, Nepa-Botuoba, Baikit and Predpatoma petroliferous region. The Cambrian petroliferous complex produces gas in the South Tunguska and Angara-Lena petroliferous region and the Turukhan-Norilsk petroliferous area.
