Purpose. The results of the hydrocarbon (HC) potential assessment of some structures and fields in Barents Sea by the frequency resonance method of the remote sensing (RS) data processing and interpretation are discussed. Design/methodology/approach. Experiments were carried out with the mobile technology of frequency-resonance processing and interpretation of remote sensing data using, which is the "direct" method of mineral deposits exploration and operates within the "substantial" paradigm of geophysical investigations. The technologies and methods, developed on the principles of this paradigm, are aimed at the searching a particular (desired in each case) substance - gold, silver, copper, lead, zinc, uranium, oil, gas, condensate etc. Findings. Seven anomalies of "oil and gas deposits" type have been discovered and mapped in the Norwegian shelf on the area of Skrugard and Havis fields’ location. Mapped large anomalous zone of the "gas reservoir" and "gas-condensate reservoir" type on the unique Shtokman field allows to conclude, that giant and unique HC deposits in the Arctic region can be detected and mapped by used mobile method. The absence of anomalous zone over Central structure on the Fedynsky high and the relatively small anomalous zone over Pakhtusovskaya structure indicate that the probability of finding giant fields within these structures is very low. Practical implications/value. Consequently, the detailed geological-geophysical studies and drilling within these structures at this stage of prospecting are impractical due to the fact that at such a distance from the coast now is economically feasible to develop only the giant and unique HC deposits. The received results show the principal possibility of remote sensing, seismic and geoelectric methods integrated application for hydrocarbon accumulations prospecting and exploration within offshore. The mobile technology of frequency-resonance processing of RS data provides a unique opportunity to operatively investigate in reconnaissance character within the Arctic region the most promising areas for the detection of giant and unique HC fields. This may significantly speed up the development of the oil and gas potential of Arctic region.
