A brief tectonic and geological overview of the fore-Urals and fore-Novaya Zemlya belt of oil and gas accumulation and the results of studying of the conditions for hydrocarbon deposits formation in uplift-thrust structures of its eastern side are presented. It is shown that the early stages of the belt formation are associated with Paleozoic subduction and obduction processes occurring in the transition zone between the Paleo-European continent and Uralian paleo-ocean located eastward (in modern coordinates) the continent. The intensive thrust-folded dislocations of the western verergency are fixed into the eastern side of the fore-Urals and fore-Novaya Zemlya belt of oil and gas accumulation. We associate their formation with the continental collision that occurred during the closure of the Uralian paleo-ocean at the Latest Paleozoic, and in the most northern segments of the belt, probably, at the Earliest Mesozoic. The structural paragenesis of the eastern side of the fore-Urals and fore-Novaya Zemlya belt of oil and gas accumulation includes uplift-thrusts and thrusts, as well as various scaled structural units formed under the conditions of the latitude compression.
