Oil and gas north of Krasnoyarsk region: problems of development and prospects for development
(Adiev R.Ya. Baldin V.A. Munasypov N.Z. )
Due to its remoteness and underdeveloped infrastructure Taimyr still remains the least explored region of Russia in regard to geology. Regional seismic explorations CDP 2D method of high distance , first carried out in Taimyr at the beginning of the XXI century, together with other geological-geophysical data allowed to modify essentially the structural model of Yenisei-Khatanga regional down fold and adjoining territories of Mountainous Taimyr, Siberian platform, Western Siberian plate. Petrolium potential of the north-east of Western Siberia, north-west of Siberian platform and western part of Taimyr fold system has been estimated from new positions. An allocation of a new oil and gas promising sedimentary basin of piedmont-type in the Riphean-Paleozoic deposits (South-Taimyr potential oil and gas bearing region - OGBR) has been founded within South-Taimyr tectonic area of Mountainous Taimyr. It is shown that the major part of Yenisei-Khatanga oil and gas bearing area (OGBA), including Ust-Yenisei trench and diagonal system of fault megalithic banks of Ob-Laptev ridge within Yenisei-Khatanga regional down fold, regarding structural and primary sedimentation features (including - spreading of Neocomian clinoform zone) constitute a part of Western-Siberian oil and gas bearing basin and form in the north of Siberia a new oil and gas bearing area with high-density ofpotential resources of hydrocarbon: Ust- Yenisei oil and gas bearing area of Western-Siberian petroleum province. In the north-west of Siberian platform where a range of big megalithic banks with oil-and-gas-promising Riphean-lower Paleozoic deposits were mapped by seismic-exploration works CDP for the first time, Igarka-Norilsk oil and gas bearing area was marked out. Prospective oil lands of forming Bolshekhetskiy oil production centre have been positioned; primary objectives on implementation of large-scale oil and gas programs in the north of Krasnoyarsk territory have been defined.......
