pdf Structural features of petroleum bearing prosprects belonging to Anabar-Khatanga saddle (Khatanga bay of the Laptev Sea and adjacent territories) - Eastern Siberia
The study is devoted to the structural characterization and analysis of petroleum potential of the Anabar-Khatanga saddle, which is located in the north-eastern part of the Krasnoyarsk Territory, north-western part of the Sakha (Yakutia) Republic and in the Khatanga Bay of the Laptev Sea. A complex analysis of seismic materials and drilling data was carried out, a set of seismogeological sections was created, and a set of structural maps and a tectonic scheme of the top Permian seismic marker were constructed. According to the results of the structural analysis, it was concluded that a large part of the Anabar-Khatanga saddle is occupied by major depressions of the Yenisei-Khatanga regional trough and the South-Laptev syneclise; in the southern part of the region is located the superorder intermediate structure North-Siberian monoclise.
The results of analytical researches showed that in the Anabar-Khatanga petroleum bearing area in the Permian and Devonian source rocks enriched with organic matter capable of generating significant amounts of hydrocarbons are developed, and in the Riphean, Lower-Middle Paleozoic, Permian and Mezozoic sections reservoir layers with good reservoir properties are identified. From the point of view of oil and gas perspective objects in the Anabar-Khatanga petroleum bearing area, the anticlinal structures associated with salt domes, lithological traps in the Permian and Mesozoic terrigenous sediments and reefogenic structures in Vendian-Cambrian and Devonian-Carboniferous carbonates are of interest.

Keywords: petroleum potential, source rock, salt dome, seismogeological section, structural map, Anabar-Khatanga saddle, Khatanga bay of Laptev Sea, Eastern Siberia.
