One of the most famous and promising shale formations in Russia is the Bazhenov formation. The ambiguity of ideas about its geological features, caused by the complex, heterogeneous structure of the strata, attracts the attention of many researchers. In this work, the Bazhenov formation is singled out in conjunction with its stratigraphic counterparts in the Bazhenov high-carbon formation (BVCHF). In this were considered the main characteristics of its allotment and distribution over the area, as well as the geological structure. Being an unconventional reservoir of hydrocarbons, BVCHF has properties of a petroleum-bearing rock, one of the main characteristics of which is organic matter, its type and maturity. The paper presents the results of the study of organic matter by various methods at the micro level, as well as their integration with larger-scale studies. The need for detailed consideration of the organic matter of the BVCHF is justified by the fact that it has a mixed composition and, as a consequence, a different degree of transformation and spatial distribution.

Results of Bazhenov formation deposits organic matter complex investigations to assess its oil generation potential and maturity are presented. Researches were performed by Rock-Eval pyrolysis, rock structure analysis using scanning electron microscopy and organic matter transformation and distribution in the bulk of rocks using luminescent microscopy. As a result of the research, the general pattern for the Bazhenov formation kerogen thermal maturity variability along Western Siberia was confirmed, and the high maturity areas delimitation around the Salym high and the Krasnoleninsky arch was significantly specified. The areas of anomalously high maturity are not related to regional patterns of sedimentation. The possible influence of thermal maturity on the unconventional reservoirs with kerogen porosity formation in the Bazhenov formation and the features of their distribution were established. High thermal maturity that refers to the end of oil window is one of the main condition for the Bazhenov formation oil capacity formation, but knowledge of maturity change through the area pattern is not a sufficient condition for unconventional reservoirs including that with kerogen porosity retrieval.

Soil-cement bricks are good examples of environmentally friendly products. This brick is the combination of soil with compacted cement with no combustion in its production. In this work the physical chemical characteristics of the soil from Piaui for producing this material were investigated. Samples of the soil were collected in three potteries from the county of Bom Jesus and pH analysis were carried out, as well as the rate of organic matter, texture, particle density, limits of liquidity and plasticity rates. The results have shown that the soils have acid tones (pH 5,49 a 6,11), which can be neutralized by adding cement, and organic matter percentages up to 1%. The samples have shown predominantly clay-rich textures with adequate plasticity limits, however, values of liquidity limits and particle density above recommended. Altogether, these soils tend to present viability concerning soil-cement brick production, provided that corrections with additives are made in order to minimize this effect.

Replenishment of oil reserves requires searching, exploration and production of new unconventional objects. Among these objects is Domanik formation, which is widespread in the Volga-Ural basin. The Domanic high-carbon formation is presented by thin-layered carbonate-siliceous rocks with a high content of organic matter, capable of both producing hydrocarbons with its own oil and gas potential, and concentraring them in reservoirs [Stupakova et al., 2017]. Study of lithological composition of rocks help to obtain information about the nature of hydrocarbon accumulations and understand possibilities of estracting hydrocarbon of them. The lithological and geochemical characteristics of rocks are an integral part of the study such types of deposits.

The report is devoted to the study of conditions for the formation of organic porosity–void spaces of organic origin formed during transformation of the organic matter into hydrocarbons, and their role in the formation of hydrocarbon accumulation in low-permeability shale strata. The experience of studying and developing known shale formations of the world testifies to the fact that such strata are hybrid phenomena, that is, they are both oiland gas-bearing strata containing traditional and non-traditional accumulations of hydrocarbons. Based on the results of the programmed pyrolysis by the Rock-Eval-6 method, an estimate has been performed to quantify organic (kerogen) porosity. This estimate allows for determining the forecast retention volume of HCs generated during catagenesis.

AbstractThe aim of this study was to determine the chemical composition of Lake Widryńskie bottom sediments (max. depth. 27.0 m, area 123.9 ha). The sampling of bottom sediments was conducted once, on 16 August 2010. Sampling was made in 10 specific areas. Among the 10 samples, 4 samples were taken from the littoral and sublittoral zones, while the rest were taken from the profundal zone. The dominant component of the sediments was silica and calcium carbonates were subdominant. Based on the survey, it was determined that silica occurred in greater numbers in littoral sediments, while in sublittoral sediments there was increased participation in the chemical composition of organic matter. The elements that build a capacity complex were a small percentage of the dry weight of sediment. Sediment from the vicinity of inflows contains higher amounts of silica, which confirmed the impact of the catchment on the chemical composition of sediments.

We conducts a systematic study on the biological sources of the sediment organic matter through the analysis of the organic carbon and nitrogen content in the sediments of Poyang Lake, the n-alkanes as biomarker and the characteristics of the compound-specific isotope of n-alkanes. It is found that the C/N ratio of organic matter is less than 10 in Poyang Lake and that the organic matter mainly originates from lacustrine aquatic organism. The short-chain hydrocarbon takes absolute advantage in the n-alkanes. The value of C21-/C22+is greater than 1, which shows that the biomass of bacteria and algae is greater than the sum of the aquatic submerged plants and terrigenous organisms biomass. The value of (nC15+nC17)/(nC23+nC25) of n-alkanes is greater than 2, which reveals that bacteria and algae have an absolute predominance in aquatic organism. The high carbon n-alkanes come from terrigenous plants and their compound-specific carbon isotope demonstrates that C3plant is the main biological source.

A sensitive and accurate method for the determination of phosphate, involving the application of the Evelyn photoelectric colorimeter to the ceruleomolybdate reaction, is described. This technique makes it possible to differentiate phosphate phosphorus from other forms of phosphorus.Conditions affecting the rate and extent of color development have been studied. The results show that the maximum color intensity is developed m about five minutes after addition of the reducing agent. The determination may be made in the presence of extraneous color, and soil organic matter does not interfere with the reaction. Under the conditions specified, using light filters, Beer's law applies to the reaction in soil extracts as well as in pure solutions in the range 0.02 to 0.40 parts per million of phosphorus.
