In 2013, based on the analysis of regional geological exploration materials for the Russian Federation territory, Rosnedra specialists planned 26 prospective zones for accelerated development of the hydrocarbon resource base. The Khantai-Severorechenskaya and South-Tungusskaya oil-and-gas promising areas are located on the right bank of Yenisei and unite lands of the Kureika-Baklanikha, Khantai-Rybninsk megaswells, Surigdakon salient and western framing of the Kureika syneclise. With the purpose of geological study of the zone, in 2014 specialists of Yenisegeophysica and SNIIGGiMS proposed a regional geological and geophysical profile along the route connecting the project sites of the parametric wells Tynepskaya 215 – Khantaiskaya 405. After repeated clarification of the state budget financing programs JSC Rosgeologiya is proceeding to field geophysical studies along this route in the current 2018 year. The project scope of work includes 2D CDP seismic survey, MTS-NFTES electrical exploration, aerogeophysical investigations (magnetic exploration, electrical exploration, gamma spectrometry) and this route is considered as a reference for planning of subsequent oil and gas prospecting in the northwestern part of the Siberian Platform. The analysis of available geological and geophysical materials along the route made it possible to substantiate levels of the section that are the most promising for oil and gas and expected local objects, to specify the list of geological tasks and coordinates of the regional profile. The results of the revision and partial reprocessing of archival geological and geophysical materials are given in this article.

Keywords: seismic survey, geophysical base line, Siberian Platform, zones promising for oil and gas, Khantai-Severorechensk, South-Tungusskaya, parametric wells Tynepskaya, Khantaiskaya.
