“…Oil companies in Russia produce 600 thousand tonnes of oil sludge annually; the total volume worldwide is 6 million tonnes. Oil producing companies account for more than 1 million tonnes of oil sludge and oil-contaminated soils; oil refineries -0.7 million tonnes; oil depots -0.3 million tonnes; other sources (railway transport, airports, seaports) -0.5 million tonnes [1][2][3]. Oily waste disposal facilities occupy dozens of hectares of territories separated out of economic use and are characterised by ecological, fire, and sanitary-hygienic danger.…”

The paper considers the problem of utilisation and neutralisation of oil sludge at oil producing and refining enterprises. Oil sludge is a complex heterogeneous mixture consisting of high-molecular oil compounds, mineral particles of different composition, and water. The authors studied the elemental composition of oil sludge of different storage periods for oil refinery production by modern analytical methods: IR spectroscopy and X-ray fluorescence spectrometry. According to the research, the main composition of the oil residue, represented by the hydrocarbon component, contains paraffin-naphthenic and heavy aromatic hydrocarbons. Moreover, its non-hydrocarbon component contains compounds Si, Al, Ca, Fe, S, Ba.

“…A substantial decrease in conventional oil and gas reserves [1][2][3][4][5] led to the establishment of three potential development trends in global energy [6]. The first trend is related to the involvement of alternative fuel resources in the area [7][8][9][10][11][12][13]; the second is related to deeper processing of conventional hydrocarbon feedstock to obtain marketable products with high added value [14][15][16][17][18][19][20][21]; and the third is related to the increasing interest in unconventional oil and gas resources [22][23][24][25][26].…”

Conversion of Organic Matter of Carbonate Deposits in the Hydrothermal Fluid

et al. 2021

This present paper investigates the conversion of organic matter in carbonate rocks of the Semiluksko-Mendymsky horizon Volga-Ural Basin under hydrothermal conditions with excess water in subcritical conditions at 613–653 K and 170–200 Bar. It has been found that the content of hydrocarbon extracts increases (relatively) which indicates the oil-generating potential of the studied deposits. Besides, it has been shown that organic matter undergoes oxidation reactions under hydrothermal conditions, as indicated by the presence of oxidized structures in the extracted hydrocarbons. Moreover, our results indicate that increasing the temperature and pressure of the used hydrothermal fluid leads to an increase in the content of n-alkanes C25-C30 and asphaltenes in the extracts. On the other hand, it has been found that saturated, aromatic hydrocarbons and resins content decreases at this stage. The obtained data about the geochemical parameters dependencies of the hydrocarbons obtained from the studied carbonate rock on temperature and pressure associated to hydrothermal effect show possible pathways of migration, genesis, and formation of hydrocarbon deposits.
