“…After the late Proterozoic uplift, sedimentation in the North Uralian foreland was resumed in Ordovician time due to the opening of the Uralian Ocean (Perfil'ev 1979 (Dakhnova et al 1995) and reservoirs at several stratigraphic levels (Dedeev et al 1994;Zhemchugova & Schamel 1994). From Artinskian to late Permian time, the onset of continental collision caused the development of the Uralian foredeep which accumulated sediments shed from the rising fold belt.…”

“…Up to 6 km of clastic deposits interbedded with evaporites and coal measures were deposited in the foredeep basin. Artinskian marine shales are enriched in type II kerogen and are considered to be important source rocks (Dakhnova et al 1995). In latest Permian-early Triassic time (250-240 Ma), the North Urals, along with West Siberia and the Barents Sea, experienced an episode of extension which was marked by basalt flows in the Kosyu-Rogovsk basin (Timonin 1975).…”

“…This is interpreted to be mainly due to the presence of Ordovician evaporites. Hydrocarbon pools are sourced mostly by Artinskian and Upper Devonian-Lower Carboniferous shales which contain kerogens of types I and II (Dakhnova et at 1995).…”

The North Urals thrust belt holds significant hydrocarbon resources hosted mainly in thrust-related anticlines mapped at the surface. N e w seismic and drilling data have permitted the identification of n e w exploration targets. The most attractive structural plays are considered to be associated with the buried antiformal stacks in front of the belt. Stacks of folded thrust sheets involve the regionally productive Silurian-Lower Permian carbonates and sandstones encased by thick Artinskian shales, w h i c h provide both the source rocks and sealing. Untested structural closures in the buried wedge-shaped thrust sheets are the primary targets for exploration. Additional prospects are predicted in the autochthonous section of the thrust belt. This play includes a subthrust continuation of inverted anticlinal zones of the Pechora-Kolva aulacogen.
