Prediction of hydrocarbon traps in the Barents Sea shelf on the basis of 2D, 3D seismic exploration
DOI 10.31087/0016-7894-2019-4-27-39
The Barents Sea region has one of the greatest potential for oil and gas fields discovery. In recent years of its exploration, the following fields were discovered: Shtokman, Ledovoe, Ludlovskoe, Murmanskoe, Severo-Kil’dinskoe. All the fields were discovered in Middle Jurassic and Triassic formations. With obtaining new data resulting from 2D and 3D seismic surveys conducted by PJSC Gazprom and containing information on the features of oil and gas bearing and oil and gas promising rock associations, it became possible to get back to the issue of oil and gas exploration paradigm. The obtained data contained information on the structure of hydrocarbon accumulations, paths of formation fluid upward migration, leading role of fault tectonics in formation of hydrocarbon fields, direction of major regional tectonic stresses, prevailing structural deformations, horizontal stresses, tectonic and physical factors affecting the vertical permeability in the subsurface, conditions of gas accumulations deforming, and much more. Thus, with acquisition of modern 3D seismic data, it became possible to get back to the issue of clarifying the petroleum potential by studying the mechanism of hydrocarbon traps formation in the context of tectonic activity of the Barents Sea paleorift system. The results of 2D and 3D seismic surveys allow extending the stratigraphic range of hydrocarbon deposits prediction from Carboniferous-Permian to Cretaceous formations. The authors identified a wide range of types of hydrocarbon traps formed in the Barents Sea Basin, namely: structural, lithological, stratigraphic, tectonic, and combination. At the same time, the proportion of structural traps is insignificant, and the majority of newly identified traps are non-structural. This paper presents the examples of delineation of hydrocarbon traps typical of Palaeozoic and Mesozoic stratigraphic series.
