Abstract

Summary

The authors continued testing the frequency-resonance method of remote sensing (RS) data processing and interpretation in the Arctic region. In 2014, for hydrocarbon accumulations prospecting the satellite images were processed over four major blocks in the Norwegian part of the former “gray” zone of the Barents Sea and over a large area in the Kara Sea.

In the Barents Sea the RS data were processed within four search sites covering 39742 km2. Area of 3D seismic work within them is 13956 km2. Two anomalous zones of the “gas deposit” type and 13 anomalous zones of “gas+condensate reservoir” type with total area of 1613 km2 were detected and mapped within investigated areas. Relative to total surveyed area (39742 km2) it is 4.06 %.

In area of Universitetskaya-1drilled well locations in Kara Sea the RS data were processed over block of 4150 km2. Four anomalous zones of “oil+gas+condensate» type and two anomalous zones of “oil+gas» type were found and mapped within survey sites. The total area of all anomalies is 510 km2. With respect to the area of the surveyed block this is 12.29%. Within the surveyed block in the Kara Sea the total area of all detected anomalies is significantly larger than those in the Barents Sea.

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 direct technology of frequency-resonance processing of RS data allow to investigate operatively in reconnaissance character the most promising areas in the Arctic region 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.
