The article highlights the functionality of the W-SEIS software developed at the IPGG SB RAS, designed to interpret 2D/3D seismic and drilling data. The application consists of a set of interconnected modules and utilities, each of which can be used as an independent software product. W-SEIS is a cross-platform software, it is developed using a client-service architecture and has high performance and imposes minimal system requirements on computer equipment.

This work is devoted to the development of a technique for automatic identification of lithological types according to well logging data in terrigenous deposits of the J1 horizon in the south of the Tomsk region.

There are six sedimentary seismic sequences overlying pre-Mesozoic basement in the Mesozoic-Cenozoic sedimentary cover of the Arctic regions of West Siberia and the Kara Sea shelf. The paper describes the seismic markers characteristics and the seismic-facial features of the Paleozoic, Triassic, Jurassic, Neocomian, Apt-Cenomanian and TuronianCenozoic seismic sequences. It was concluded that the features of large Cenomanian gas pools are seismic markers associated with gas-water contacts; Apt-Albian pools are displayed on time sections by a bright spot seismic anomaly.

В работе рассмотрено геологическое строение Троицко-Михайловского соляного вала, восстановлена история его геологического развития, реконструирован полный геологический разрез исследуемой территории с учетом перерывов в осадконакоплении. Определены длительность и масштабы размывов для каждого из пяти перерывов в осадконакоплении начиная с позденевендского времени. На основе модели региональных тектонических движений и скорости осадконакоплния математическим путем рассчитана эволюция всплывания солей сквозь вышележащие более плотные толщи на основе решения уравнения неустойчтивости Рэлея-Тейлора. Конечный результат эволюции хорошо согласуется с наблюдаемой структурой вала, выявленной по сейсмическим данным. По результатам моделирования установлено, что рост вала начался в конце пермского периода и был спровоцирован региональными тектоническими движениями, наиболее активно проявившимися в триасе. Формирование вала продолжается до сих пор, компенсационные синклинали, обрамляющие вал и выполненные мезозойскими отложениями, имеют конседиментационный генезис.

The study presents a seismic and geological characterization of the Meso-Cenozoic sedimentary cover of the Nadym-Pur interfluve area and discusses the morphology of the Jurassic and Aptian-Albian-Cenomanian sedimentary complexes, formation history of structures, and geologic processes responsible for the formation of Cenomanian gas accumulations.

Regional model of the geological structure of the Paleozoic Western Siberia was considered; oil-and-gas macroblocks located in the Ural and Pre-Yenisei areas and in the inner region of the plate were allocated. The structure and types of oil-and-gas objects of Pudino-Alexandrov macroblock were considered. Criteria of oil-and-gas objects from the seismic data were formulated.

The articles describes the plug-in for Petrel software. It provides automatic detection of reservoir boundaries in well profiles and structural analysis of surfaces.
