The Timan-Pechora oil-gas basin: A geological review
- Geological Survey, Reston, VA (United States)
At the base of the sedimentary section of the Timan-Pechora basin are Late Precambrian rifts, which are filled by unmetamorphosed sedimentary rocks 10 km and more than 10 km thick. The upper parts of these rift deposits have potential for gas. Structurally the Phanerozoic sedimentary fill of the basin is mildly deformed in the west and central parts into several broad depressions and more narrow intervening highs. The eastern part is strongly deformed by overthrusts that were emplaced in the Late Paleozoic in connection with development of the Ural fold belt. Eight oil-gas plays are recognized in the basin: 1-Ordovician-Lower Devonian, 2-Middle Devonian-lower Frasnian, 3-upper Frasnian-Tournaisian, 4-Lower Carboniferous, 5-upper Visean-Lower Permian, 6-Lower Permian, 7-Upper Permian, and 8-Triassic. The promising oil-gas basin is of great interest for global stratigraphy and tectonics as well as for petroleum exploration. 18 refs., 7 figs., 1 tab.
