In-depth additional studies were carried out to assess oil and gas potential of deep-lying Jurassic and pre-Jurassic deposits of the northern territories of Western Siberia. As in previous work, the geological and mathematical program “Vybor” was used. Based on the first constructed series of model maps with probabilistic values of informative geochemical and geological parameters, the most promising both local and regional objects were selected. Increasing complexity of the traps structure with depth was noted. As a rule, from the Cretaceous deposits to the Jurassic and Paleozoic, the type of trap from the predominant anticline (in the Cretaceous) changes to a much more complex combined one, which requires special approaches (and new technologies) to identify and explore such objects. Studies based mainly on seismic data indicate rather high oil and gas content of both the Paleozoic and Triassic deposits, which have a platform occurence and large thicknesses, as well as crystalline basement formations. In this regard, unconventional combined traps of deep-lying deposits of the North of Western Siberia are of significant interest in terms of incremental oil and gas resources and reserves.

Data Generalization

The resource base of Western Siberia needs to be replenished to maintain the current development indicators. The reserves associated with the classic structural traps were diagnosed and mapped for the main horizons in Western Siberia. Replenishment of the resource base at the expense of such reserves is ineffective due to the fact that undiscovered traps of these types are thin, or lie at great depths, which ultimately negatively affects the quality of the resource base and the economic efficiency of their involvement in development. The driver of the growth and replenishment of the resource base under current conditions is the Achimov deposits, which are ubiquitous in this area at depths of 2500–3500 m and are genetically deep-water deposits of fans. The advantage of involving these deposits in development is often associated with the confinement to existing assets, where production is carried out from above and below-lying geological objects, the complexity is associated with the lithological type of traps, which is not diagnosed by direct analysis of seismic materials, as well as the extremely poor knowledge of the deposits over the area. Considering that the variability of properties over the area is a distinctive feature of Achimov deposits, the factor of poor knowledge by drilling significantly complicates the understanding of the potential of the deposits. In order to identify and assess the most promising areas for involvement in the development of the Achimov deposits, in PJSC Gazprom Neft the work “Regional assessment and zonal study of the prospects for oil and gas potential of the Achimov formation in the Western Siberia” was carried out. The goal and objectives is to form a reliable tool for searching and forecasting potential options using the generated regional maps of criteria (various characteristic properties and their combinations) built on the basis of data generalization throughout Western Siberia.

The geodynamic development of the north–western (Arctic) margin of the Siberian craton is comprehensively analyzed for the first time based on our database as well as on the analysis of published material, from Precambrian-Paleozoic and Mesozoic folded structures to the formation of the Mesozoic-Cenozoic Yenisei-Khatanga sedimentary basin. We identify the main stages of the region’s tectonic evolution related to collision and accretion processes, mainly subduction and rifting. It is demonstrated that the prototype of the Yenisei-Khatanga basin was a wide late Paleozoic foreland basin that extended from Southern Taimyr to the Tunguska syneclise and deepened towards Taimyr. The formation of the Yenisei-Khatanga basin, as well as of the West-Siberian basin, was due to continental rifting in the Permian-Triassic. The study describes the main oil and gas generating deposits of the basin, which are mainly Jurassic and Lower Cretaceous mudstones. It is shown that the Lower Cretaceous deposits contain 90% of known hydrocarbon reserves. These are mostly stacked reservoirs with gas, gas condensate and condensate with rims. The study also presents data on oil and gas reservoirs, plays and seals in the Triassic, Jurassic and Cretaceous complexes.

Unique Leningradsky and Rusanovsky gascondensate fields in the Barrem-Cenomanian layer are discovered in the Kara Sea. Non-industrial accumulations of oil and gas have been discovered in the Lower Cretaceous sediments of the western part of the Barents Sea shelf. However, the structure and oil and gas potential of the Lower Cretaceous sediments of the Barents-Kara shelf remain unexplored. Based on the seismic-stratigraphic and cyclostratigraphic analysis, a regional geological model of the Lower Cretaceous deposits of the Barents-Kara shelf was created, the distribution area and the main stages of the accumulation of clinoforms were identified. As a result of a detailed analysis of the morphology of clinoform bodies, paleogeographic conditions were restored in the Early Cretaceous and a forecast of the distribution of sandy reservoirs was given

Despite the recent increased interest of researchers in the pre-Jurassic deposits of Western Siberia, this complex of rocks still remains relatively unexplored. In this paper, we consider fields that are in close proximity to each other, but have. fundamentally different geological structure and criteria for the oil and gas content of rocks that form the top of the pre-Jurassic complex.

The features of the geological structure and oil and gas potential of the Bazhenov-Abalak oil and gas complex are discussed. Based on new geological and seismic data, using an integrated approach, the zones of distribution and the boundaries of thinning out of silty sand reservoir rocks of Vogulkinskaya strata were mapped, four traps and two zones (Ourinskaya, Eastern Tolumskaya), which are perspective for hydrocarbon deposits search, were distinguished. In Bazhenov horizon, the zones of development of anomalous sections and bituminous sediments were mapped, laying above Bazhenov formation, which are perspective for hydrocarbon deposits search. Recommendations for further exploration are given.
