Geological Structure and Petroleum System of South Kara Basin

Geological model of South Kara basin (SKB) based on 2D seismic and regional lines 2-AR and 3-AR. The SKB is filled by Upper Triasic(?)-Cenosioc clastic sediments together with the Late Permian(?)-Mid Triassic synrift megasequence. The rifts base is tracked at the depth up to 11-12 km. Using new seismic data, we identify grabens and semi-grabens at the base of the basin. They are filled by partly deformed sediments. The 3D basin model is done and shows oil and gas windoows. Many structures identify on Paykhoy-Prinozemelskiaya monokline such as Universitetskaya, Vikulovskaya and Tatarinovskaya.
