pdf Characteristics of organic matter contents in bituminous Upper Jurassic rocks of the southwestern and central regions of Western Siberia according to pyrolytic studies results
The paper presents the pyrolytic studies results of bituminous Upper Jurassic various facies core belonging to various poorly studied section types within the southwestern and central regions of Western Siberia.
Based on the new obtained data were created and clarified maps of average TOC and the catagenetic maturity stage of the organic matter in the Upper Jurassic strata, determined from calculated values of the vitrinite reflectance index (R0) through the Тмах parameter. Significant changes in autochthonous organic matter compositions of the Upper Jurassic strata within the study area and their relationship with the level of its catagenetic maturity were established. The unique data of the kerogen type and the Mulymya Formation organic matter content from new exploration wells allow us to revise high-carbon Upper Jurassic rocks regional distribution patterns, which contained huge hydrocarbon resources.

Keywords: organic matter, Upper Jurassic strata, bituminous rocks, pyrolytic studies, Western Siberia.

pdf Petrophysical characteristics of the Late Jurassic - Early Cretaceous productive levels of the Sredne-Nazym field
The article is devoted to the development of approaches to the allocation of reservoirs in such a complex object as the Late Jurassic - Early Cretaceous sequences of Western Siberia. Based on the generalization and systematization of laboratory core studies, well logging and field data, the main lithological types of potential reservoirs rocks are identified, their petrophysical characteristics are given, the position in the section and patterns of distribution over the area are determined using the example of the Sredne-Nazym field. The reservoirs are divided into two types: 1st type - rocks with reservoir properties corresponding to traditional reservoirs; 2nd type - poor-porous potential reservoirs that could be involved in development only after technological impacts - hydrochloric acid treatment or hydraulic fracturing. The obtained results are used in planning the development of the Late Jurassic - Early Cretaceous sections, which is currently carried out using horizontal wells.

Keywords: Late Jurassic-Early Cretaceous, lithotypes, well log interpretation results, geochemical studies, Sredne-Nazym field.
