C and O isotope composition of secondary carbonates in the volcanites of the pre-Jurassic complex of the Western-Siberian Plate

Moscow University Bulletin. Series 4. Geology, 2019
The carbon and oxygen isotopic composition of secondary carbonates from acidic effusives fro investigated. Ϭ13С (VPDB) and Ϭ18О (VSMOW) values of siderite vary from –6,6 to –2,4‰ m the top of the Western Siberia pre-Jurassic complex (Tomsk Region) was and from 7,8 to 12,3‰, while Ϭ13С and Ϭ18О values of calcite vary from –8,9 to –8,4‰ and from 2,5 to 3,

Geological Structure of The Pre-Jurassic Complex Within The Elizarovsky Trough of The Frolov Megadepression and The Galyanovsky Nose of The Krasnoleninsky Arch According to Seismic Data CDP 3D

Tyumen 2021, 2021
Summary The generation of terrigenous super reservoirs is not always determined by the primary sedimentation conditions and the quality of sand material; often reservoirs with good reservoir properties are formed during diagenetic changes in rocks. Reconstruction of diagenetic processes and superimposed changes in sedimentary material, leading, in the ...

REGIONAL PATTERNS OF OIL AND GAS POTENTIAL OF THE PRE-JURASSIC COMPLEX ON THE EXAMPLE OF THE TOMSK REGION AND THE KHANTY-MANSI AUTONOMOUS DISTRICT

ГЕОФИЗИКА, 2022
В статье рассмотрены данные по нефтегазоносности пород доюрского комплекса (ДЮК) в пределах Томской области и Ханты-Мансийского автономного округа. Проведенный анализ позволил выявить ряд закономерностей расположения залежей углеводородов в зависимости от структурно-тектонического положения, а также вещественного состава коренных пород, слагающих ...

Prospects of productive strata of the pre-Jurassic complex of Western Siberia for the discovery and involvement in the development

Oil and Gas Studies
   The article discusses the prospects of productive strata of deposits of the pre-Jurassic complex of Western Siberia for searching, forecasting and involving in the development. Some features of the geological structure of Triassic volcanic-sedimentary deposits and formations of the Paleozoic basement have been identified within the pre-Jurassic ...

Pre-Cretaceous Prospectivity of the Outer Møre and Vøring Basins Constrained by New 3D Seismic Data

80th EAGE Conference and Exhibition 2018, 2018
Summary The outer More and Voring basins offshore mid-Norway are vast underexplored areas. By integrating interpretation of new seismic 3D data, as well as regional 2D, 2Dcubed, and potential field data, we identify new targets for future hydrocarbon ...

JOINT ANALYSIS OF AZIMUTHAL ATTRIBUTES AND DIFFRACTION ENERGY FOR PREDICTING PERSPECTIVES IN THE PRE-JURASSIC COMPLEX WITHIN NYUROL STRUCTURAL FACIAL ZONE OF WESTERN SIBERIA

ГЕОФИЗИКА, 2023
В статье рассмотрены подходы к прогнозу перспектив нефтегазоносности в интервале доюрского комплекса в пределах Нюроль- ской структурно-фациальной зоны Западной Сибири. Поскольку фундамент преимущественно представлен плотными породами с непроницаемой матрицей, то перспективы интервала связаны в первую очередь с выделением областей повышеннои ...

Petrogenetic typing of volcanics from the top of the oil-bearing pre-Jurassic complex in the Elizarovsky trough of the West Siberian Plate

Russian Journal of Earth Sciences
The results of petrogenetic typing of acidic volcanic rocks (rhyolites and dacites) of the top of the oil-bearing pre-Jurassic complex of the field located in the Elizarovsky trough of the West Siberian plate are considered. These volcanic deposits have a complex structure and, according to the results of well sampling, are characterised by extremely ...
