New approach to hydrocarbon exploration in Permian terrigenous formations of the north-eastern part of the Timan-Pechora Province
The paper discusses a new approach to hydrocarbon exploration in the Permian terrigenous formations. Geological and geophysical materials of various years are analysed; model of the Permian series is created; formation conditions for different types of traps and hydrocarbon reservoirs are ascertained. Studies and analysis of formation mechanism for different types of traps within the facies and dynamic zones of activity and stability made possible their typification and subsequent classification taking into account a genetic type of structural form of the upper impermeable bed, morphology, and manifestation of Permian terrigenous formations in the wavefield. The studies resulted in the development of the prospecting morphogenetic classification of different trap types; this classification can be used for traps prediction and identification in the early exploration stages within the north-eastern part of the Timan-Pechora Province. Zones of concentration of traps having different genesis are identified with the purpose to predict oil and gas occurrence within the Permian terrigenous formations in the north-eastern part of the Timan-Pechora Province. Particularity of
the paper is in the algorithm of a new prediction methodology described, which will allow revising the petroleum potential of the north-eastern part of the Timan-Pechora Province, including the Arctic shelf. The developed methodology allows revising the petroleum potential and estimating the undiscovered hydrocarbon resources in the underexplored but highly promising hydrocarbon play, determining the prospecting vectors and efficient complex of exploration activities in the north-eastern part of the Timan-Pechora
Province, including the Arctic shelf.
Key words: new approach; methodology; formation conditions; geological model; energy zones; trap; reservoir.
