Abstract
The current state, structure of total hydrocarbon resources (THCRs), their spatial distribution, and interrelation determine, as is known, the strategy and tactics of further exploration. Practical experience in evaluating THCRs showed that the most reliable results are obtained most often for zones of oil and gas accumulation (ZOGA) or their parts. The following main ZOGA have been isolated on the Barents Sea shelf: (a) in the northern sea part of the Timan; (b) in the South Barents gas and oil region; (c) in the North Barents potential oil and gas region and adjacent regions. The following main ZOGA can be distinguished on the shelf of the Laptev Sea: Minin arch, Trofimov zone of uplifts, Middle Laptev saddle, and the sea parts of the Lobaz-Nordvik and Tuvan`-Anabar arches in the Khatanga Gulf. Seismic exploration to prepare local structures for deep drilling and drilling of individual parametric and exploratory wells is most expedient in the following ZOGA: Luna, Nadezhda, Gusinozemel`sk, and Admiralteistvo in the Barents Sea; Obruchev and Skuratov in the Kara Sea; Minin and Trofimov in the Laptev Sea. When planning offshore exploration and the presence of ZOGA with a high concentration of THCRs is a necessary but not a sufficientmore » condition, since the existing arsenal of technical means is limited. This especially concerns the development of offshore fields, particularly in waters with severe ice conditions. Therefore, it is necessary to take into account the technical accessibility of various ZOGA for the complete cycle of works on developing offshore fields.« less
