Objects of fold-and-thrust genesis: petroleum potential of Urals foredeep northern segment

A considerable amount of geological and geophysical material has been analysed. Prediction of oil and gas occurrence in the objects of fold-and-thrust genesis is presented. Proposals on focus areas and types of geological exploration activities within the Urals Foredeep northern segment. It is found that for various reasons (technological, because of complex geological structure) some of the promising local objects remain underexplored. Integrated studies of the previously suggested models of their geological structure (both structural framework and identification of overlooked promising intervals of the section), additional seismic surveys, and drilling wells are necessary. For certain tectonic elements, low effectiveness of exploration is associated with the fact that the regional stage of investigations is not completed. The authors recommend drilling of stratigraphic wells for the following purposes: determination of velocity characteristics of penetrated section; unbiased interpretation of legacy 2D CDP seismic data; and building reliable regional models of geological structure of the Vorkutsky transverse uplift and southern blocks of the Chernyshev Ridge
