These differences were in large measure controlled by their geodynamic settings. A typical scenario of the continental marginal basin which subsequently was modified in the foredeep basin took place in the Timan-Pechora basin. The sedimentary fill of the basin is made up of the Phanerozoic deposits only. The principal oil source rock is provided by the prolific Domanik Suite broadly developed in is eastern part of the basin. The mature Domanik source rocks charged the majority of oil and gas fields of the Timan-Pechora Basin. In the Volga Urals basin the sedimentary fill includes two overlapping foredeep sequence – Riphean and Paleozoic, of which the Riphean one is much thicker. The Riphean depocenters were subjected to structural inversion during the docking of the Magnitogorsk island arc to the Uralian margin in the Middle Devonian-Frasnian. The inversion was accompanied by the thickening of the Riphean section due to the reactivation of the pre-existing Precambrian deformation and caused the regional uplift in the Southern Uralian Foreland. This uplift led to shifting of the Domanik troughs to the westerly outboard part of the Volga-Uralian Basin. The Domanik source rock remained immature over much of the Southern Uralian Foreland which is interpreted to be a result of the inversion of the Riphean depocenters and related regional uplift. It is proposed that the enormous clustering of large oil deposits in the Paleozoic section of the south-eastern part of the Volga Uralian Basin was to a much extent produced by the charging from the multi-kilometer thick Riphean section of the Southern Uralian Foreland.","PeriodicalId":43752,"journal":{"name":"Georesursy","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67538217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main Upper Jurassic-Early Cretaceous SR of Western Siberia is represented on the Krasnoleninsky arch by the Tutleim formation (fm) (J3tt–K1v). It is overlain by argillaceous rocks of the Frolov fm (K1v–K1a), underlain by the Abalak (J2cl–J3km), Tyumen (J2a-b), Sherkalin (J1) formations and folded pre-Jurassic basement. All these formations potentially contain SR layers. The purpose of the article is to determine the sources of oil in the Krasnoleninskoe field by comparing oils with SRs and to determine of the history of oil composition formation. Based on a review of known geochemical parameters and the results of statistical analysis new molecular parameters for determining the type of organic matter (OM) and its maturity are proposed. A secondary processes of the oils of the Vikulov fm of the Kamennaya crest has been established, which is associated with the migration of hydrocarbons from the Vikulov fm to the overlying deposits. It is shown that the oils of the Vikulov fm of Kamennaya crest were formed from the SR, which was at the MC2 substage during the generation of hydrocarbons, and the oils of the Jurassic and pre-Jurassic deposits were formed on the end of MC2-beginning of MC3 substages. It was determined that the oils of Kamennaya crest have aquatic initial OM, aquatic OM was found in the Tutleim and Tyumen SRs. According to the criteria of OM type and its maturity, the source of Kamennaya crest oils cannot be determined; therefore, genetic features of the difference between the aquatic OM of the Tyumen and Tutleim formations were found. These features made it possible to estimate the source of oils for different parts of the Krasnoleninskoe field: for Kamennaya crest the Tutleim fm, for the Talinskaya area the Tyumen fm, for the Em-Egovskaya area, the Tyumen and Tutleim formations. Estimation of the contribution of the Sherkalin and Abalak SRs to the formation of hydrocarbon accumulations is beyond the scope of current work.","PeriodicalId":43752,"journal":{"name":"Georesursy","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43759962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The uniqueness of the field lies in the shallow depths of productive deposits. The oil-saturated layer is 100 m. The shallow depths of productive formations led to low formation temperature and pressure. Under such conditions, oil is inactive, characterized by high viscosity, and dissolved gas is practically absent. The features of the formation of the sedimentary cover in the area of the field predetermined the block structure, while the rocks of the productive horizon are characterized by a complex system of vertical fractures, which greatly complicates the process of oil recovery.

One of the key problems in assessing the petroleum potential of the North Kara Sea Basin and the adjacent North Barents Sea Basin is the lack of a proven stratigraphic model of the sedimentary cover.\u0000\u0000The article presents a model of the structure of the sedimentary cover of the northern part of the Barents-Kara Sea region based on the analysis of the regional seismic data and comparison with outcrop sections of the archipelagos and adjacent land. The structure of the archipelagos is determined by tectonic events and rearrangements, which also reflect on the structure of the offshore sedimentary basins. In the structure of the northern part of the Barents-Kara Sea region, three large structures can be distinguished: North Barents Sea Basin, East Barents Steps, and North Kara Sea Basin. The East Barents Steps formed during Baikal orogeny and in the Riphean-Early Paleozoic time were uplifted, and separated the North Barents Sea and North Kara Sea basins.\u0000\u0000The North Kara Sea Basin was probably formed in the Riphean and subsided in the Early Paleozoic, while the section of the North Barents Sea Basin is composed of a thick of Upper Paleozoic-Mesozoic sequence.

The existing system of transportation of mineral raw materials by sea, rail, inland water, road and air transport is considered. The description of mineral resource centers forming the cargo base of the Arctic transport system is given; their typification by types of transport for the export of products is given. A change in logistics schemes in connection with access to new markets in the changed geopolitical conditions was considered. The need for changes does not apply to rail, inland water, road and aviation transport, which provide mainly domestic transportation. Major changes affect pipeline and maritime transport. It was concluded that it is necessary to create liquefied natural gas production facilities at the exit points to the coast of the poorly devoured seas of main gas pipelines in order to monetize pipeline gas and expand the throughput capacity of main oil pipelines suitable for port oil loading terminals of the Baltic and Black Seas. The conditions for delivery to Asian oil export markets by sea have deteriorated due to the increase in the duration of circular flights and the cost of tanker freight. In addition, the possibility of an increase in the cargo traffic of the oil export to the Asian market in the Northern Sea Route was questioned due to the lack of a high deadweight cargo fleet and the required Arctic ice classes. The proposal on the need to revise strategic planning documents adopted in other political and economic conditions based on the current realities is justified.","PeriodicalId":43752,"journal":{"name":"Georesursy","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45512076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
