“…The huge amount of heavy oil and natural bitumen resources are concentrated in the territory of Tatarstan, in deposits of Permian system [1][2][3][4][5][6][7][8][9][10]. The development of heavy oil fields seems to be an important and urgent task in respect of strengthening the hydrocarbon resource base and maintaining oil production at the proper level.…”

“…Works on finding optimal technologies aimed at increasing the efficiency of developing deposits of heavy oils and natural bitumens using thermal methods are carried out in many research centers and oil-producing companies [15][16][17][18][19][20][21][22][23][24][25][26][27]. Difficulties arising from the development of heavy oil fields are associated with two problems: first, unfavorable reservoir properties-low thermal conductivity, low permeability, and lack of reservoir energy; second, the hydrocarbon component of the bituminous reservoirs is in an inactive state [4,7,10,12,13,15,19]. The immobility of hydrocarbons in the Permian strata is associated with its quality and with the geological and environment conditions.…”

The features of the oil-bearing capacity of the productive strata of Permian deposits in the interval of 117.5-188.6 m along the section of individual wells of the Ashal’cha field of heavy superviscous oil (Tatarstan) were revealed depending on the content, composition, and thermal effects of organic matter (OM) oxidation in the rocks. It is shown that the rocks are very heterogeneous in their mineral composition and in the content of both free hydrocarbons by extraction with organic solvents and insoluble OM closely associated with the rock. The total content of OM in rocks varies from 1.72 to 9.12%. The features of group and hydrocarbon composition of extracts from rocks are revealed depending on their mineral composition and the content of organic matter in them. According to the molecular mass distribution of alkanes of normal and isoprenoid structure, extracts from rocks are differentiated according to three chemical types of oil: type A1, in which n-alkanes of composition C14 and above are present, and types A2 and B2, in which n-alkanes are destroyed to varying degrees by processes microbial destruction, which indicates a different intensity of biochemical processes in productive strata of Permian sediments. These processes lead to a decrease in the amount of OM in the rocks and an increase in the content of resins and asphaltenes in the oil extracted from them, as well as an increase in the viscosity of the oil. Using the method of differential scanning calorimetry of high pressure, it was found that the studied rock samples differ from each other in quantitative characteristics of exothermic effects in both low-temperature (LTO) 200-350°С and high-temperature (HTO) 350-600°С zones of OM oxidation. The total thermal effect of destruction processes of OM depends on the content of OM in the rocks and its composition. The research results show that when heavy oil is extracted using thermal technologies, the Permian productive strata with both low and high OM contents will be involved in the development, and the general thermal effect of the oxidation of which will contribute to increased oil recovery.

“…Commercial processes such as Galoter, Paraho, Fushun, Alberta Taciuk, Kiviter, and Pertosix Lurgi‐Ruhrgas or TOSCO II have been established and are discussed in the literature. [ 145,146 ] The Paraho retorting system, [ 147 ] as demonstrated in Figure 6, follows three main sections in a continuous dynamic bed, namely the retorting (where the mist of vaporized oils and pyrolysis shells are formed), combustion, and cooling zones. The process takes place in a vertical kiln where condensed oils are recycled and returned to the kiln to maximize the efficiency and conversion ratios.…”

“…The Tosco‐II technology, which was developed by the American shale retorting company Tosco, [ 154,155 ] employs the gas heating carrier method (the gas can be accompanied by a ceramic balls heat carrier). The Tosco‐II technology has the advantages of a high oil yield percentage, excellent use of oil shale, and high energy efficiency.…”

Depleted fossil fuel resources have led to an investigation of other promising alternatives such as renewable and unconventional energy sources. Shale formations have limited permeability. Therefore, several extraction techniques have been applied to improve residual oil recovery and production. In this work, the techniques applied above ground to extract the organic fractions from oil/gas shale are discussed. Studies related to compositional fractionation, ultrasonic-assisted, microwave-assisted, supercritical fluids, and surface retorting techniques have been conducted systematically in approximately 150 scholarly articles over the past 10 years. The impacts of each technique as well as the drawbacks and challenges are highlighted in this paper. The fractionation techniques are sufficient in general; however, they are time consuming as they include several stages and use a considerable amount of solvents. Ultrasonic and microwave techniques are highly reliant on formation transparency linked to the organic fraction heterogeneous distribution. The surface retorting method, which is highly efficient with up to 90% recovery, for example, the Galoter and Paraho methods, is still dependent on shale particulate size, generates a massive amount of spent shale as waste, and is prominently emissive. Therefore, assessments that can be used to overcome existing drawbacks are considered. This can provide practical insight about these techniques to overcome limitations and concerns in terms of efficiency, cost, environmental issues, and reliability features. The work highlights the dominant extraction techniques for further development.

State Guarantees of the Right to Housing for War Veterans: Substantive and Procedural Aspects

et al. 2020

The purpose of the article was to reveal the problematic aspects of the realization of the right to housing by war veterans who participated in counter-terrorism operations / joint operations. I am interested in observing the protection of this right in civil, criminal and executive proceedings based on national and international law. The methodological basis of the study includes general and special methods of scientific research (historical, statistical, formal logic, comparative legal and structural logic). Statistics are given on the number of war veterans (combatants) as of 2019-2020, in the dynamics of providing them a living space in Ukraine during 2015-2020. In addition, the article provides examples of the elimination of conflicts of laws and ambiguous judicial practices of application of civil, family, housing and social law, as well as civil, criminal and executive procedure in the field of exercise of the right to housing by combatants and their families, protection of this right before the courts and execution of decisions in this category of cases. The results of this work can be useful for combatants who need to improve their living conditions, as well as for human rights defenders who help these people.
