“…The most probable regions of accumulation of the hydrocarbons in the reservoirs of the Apt-Upper Cretaceous sediments of the North Chukchi trough and the East Novosibirsk syneclise (mega trough) are located mostly within their close-to-boundary zones at the depths of less than 5 km. Within the Laptev Sea sedimentary basin along with the close-to-boundary zones of accumulation of the hydrocarbons there can be noted its central region, where deposits of the hydrocarbons can be formed at the depth of more than 5 km [3], [4]. Within the Paleogene sedimentary complex accumulations of the hydrocarbons are predicted primarily in the central parts of the modeled sedimentary basins and to a less extent -in their close-to-boundary zones.…”

Analyzing the results of the basin modeling using software complexes, preparing of the maps of the generation and accumulation hydrocarbon systems in the waters of the Eastern Arctic is performed. Studying of sedimentary complexes was performed and graphs of geological events were plotted within the limits of five hydrocarbon systems. Land prospectivity categories were defined in accordance with estimates of the specific densities of the default predicted resources.

“…Characterizing distribution of the fluid traps it should be noted that powerful and having lengthy strikes fluid traps were not revealed in the Paleogene and Miocene sediments on the continental mainland of the Anadyr OGPR. Terrigenous sediments of the bottom parts of the Mainitsky formation and the strata of the argillites and solid sandstones of the Miocene can be regarded as local covers [9]. In the offshore part of the region, the analogs of the Eocene-Oligocene Mainitsky horizon existing in the continental mainland can be represented as the regional fluid traps within the Paleogene section.…”

The results of studying the hydrocarbon systems with application of the modelling techniques using the Schlumberger PetroMod software complexes are considered. Modeling of sedimentary basins of the Bering Sea and their hydrocarbon systems is performed. Estimation of the probability of discovery of oil and gas accumulations related to the marine hydrocarbon systems showed that the highest probabilities of the discovery characterize the GAHS correspondent to the Eocene-Miocene (Mainitsky-Sobolkov) sediments. Probabilities of discovery of the deposits within the younger Gagarin-Avtatkul hydrocarbon systems (Lower to Middle Miocene) are substantially lower. The perspectives of discovery of oil and gas accumulations are related to oil and gas generation and accumulation capacities of insufficiently studied and distributed along the area of the deep-water region Cretaceous-Cenozoic or more ancient sloping deep sea sedimentary complexes, total capacity of which is higher in the northern and eastern near-slope zones of the Aleutian basin comprising 6 to 8 km or more. Studying of the above complexes would apparently facilitate a substantial increase of total hydrocarbon potential of the Bering Sea.

“…Therefore, Y and Ho often exhibit identical geochemical behavior in geological environments [76]. Previous studies have shown that partial melting and fractional crystallization cannot fractionate Y and Ho, and the Y/Ho ratio in igneous rocks is~28 [77]. However, these two elements may be significantly fractionated in aqueous solutions [76], such as in seawater, river water, and hydrothermal fluids.…”

Element exchange and enrichment during fluid-rock interactions are common, providing potentially novel proxies to trace hydrocarbon migration in addition to the traditional organic geochemistry tracers. However, the processes, mechanisms, and geological and geochemical fingerprints of these interactions are complex, hampering the applications of hydrocarbon migration tracers. To investigate such interactions, we conducted a petrological, mineralogical, and in situ and bulk geochemical study of authigenic quartz and whole-rock samples from the Mahu Sag, northwestern Junggar Basin, northwest China. We found that dissolution, clay and chlorite formation, and overgrowth occurred on quartz grains in hydrocarbon fluid migration pathways, suggestive of strong fluid-rock interactions. In situ quantitative elemental analysis of quartz grains revealed elemental enrichment (e.g., Mn, Fe, Al, Sr, and W) in quartz overgrowth rims compared with their cores, indicating that migration of hydrocarbon-bearing fluids in reservoirs may promote elemental exchange between fluids and minerals. Whole-rock geochemical analysis showed that decreasing contents of some elements may reflect the direction of hydrocarbon-bearing fluid migration and can be monitored with three geochemical proxies, which are the MnO contents and MnO/Zr and Y/Ho ratios. Our data provide new constraints on fluid-rock interactions in petroleum reservoirs and have implications for using inorganic geochemical methods to trace hydrocarbon migration.
