The aim. Study of the ecological state of the Voronezh reservoir under conditions of “blooming” of water by cyanobacteria. Materials and Methods. EEvaluating water quality data of hydrochemical analysis, assessment of suspended solids distribution and temperature in the water area, materials of hydrobiological study (phytoplankton), microcystin content in water have been taken into account. Results and Discussion. The direction of anthropogenic changes occurring in the ecological state of the reservoir has been traced for 2016–2022.

Geological Structure and Prospects of Oil and Gas Content of Chembarsko-Petrovskaya Zone Dislocations of Ryazan- Saratov Mega-deflection

Authors: Piataev A. A.

Up to the present time the territory of Ryazan-Saratov mega-deflection including dedicated to it Chembarsko-Petrovskaya zone of dislocations for oil and gas remains poorly studied by modern geological and geophysical methods of exploration and deep exploratory drilling. In this paper the characteristic of the geological structure of a complex of Paleozoic rocks and identified deposits and deposits discovered in the Devonian and Carboniferous oil and gas complexes in

Reconstruction of the Late Vasyuganian Sedimentation Settings Within the Middle of Group of Fields

Authors: Goncharenko O. P., Astarkin S. V., Dzhoni S. N.

The paper deals with the results of complex lithology-facies examination of the UV1 1 layer within the Middle Ob group of fields. It is found that in the area under investigation, the layer was formed in the littoral-marine and shallow-water marine conditions under the effect of waves and currents. A paleogeographic chart has been constructed for the period of the UV1 1 layer generation in the Vasyuganian formation; forecast has been made as to the development of improved reservoir rocks.
