Hydrocarbon Reserves

Hydrocarbon reserves within the middle Jurassic deposits are predominantly classified as hard-to-recover. The legislation of the Russian Federation stimulates extraction of this type of reserves by providing tax incentives, which currently make field development more attractive for oil companies. A particular interest is the Ju2 deposits of Tyumen suite because they are considered as productive almost on all explored fields. However, at the moment, the majority of deposits within this formation remain undeveloped. The main reason for this is the failure in prediction of net pay (thickness) and as a consequence mistakes in geological models for drilling production wells. This article is dedicated to the problem of spatial depositional environments prediction of the Ju2 deposits of Tyumen suite. As part of the problem solving, the geological model of studied field has been improved by integrated use of geological and geophysical information on different scales involving cutting-edge technologies in seismic interpretation.

Summary A casual reading of the SPE/WPC (World Petroleum Congresses) Petroleum Reserves Definitions (1997) and the U.S. Securities and Exchange Commission(SEC) definitions (1978) would suggest very little, if any, difference in the quantities of proved hydrocarbon reserves estimated under those two classification systems. The differences in many circumstances for both volumetric and performance-based estimates may be small. In 1999, the SEC began to increase its review process, seeking greater understanding and compliance with its oil and gas reserves reporting requirements. The agency's definitions had been promulgated in 1978 in connection with the Energy Policy and Conservation Act of 1975 and at a time when most publicly owned oil and gas companies and their reserves were located in the United States. Oil and gas prices were relatively stable, and virtually all natural gas was marketed through long-term contracts at fixed or determinable prices. Development drilling was subject to well-spacing regulations as established through field rules set by state agencies. Reservoir-evaluation technology has advanced far beyond that used in 1978;production-sharing contracts were uncommon then, and probabilistic reserves assessment was not widely recognized or appreciated in the U.S. These changes in industry practice plus many other considerations have created problems in adapting the 1978 vintage definitions to the technical and commercial realities of the 21st century. This paper presents several real-world examples of how the SEC engineering staff has updated its approach to reserves assessment as well as numerous remaining unresolved areas of concern. These remaining issues are important, can lead to significant differences in reported quantities and values, and may result in questions about the "full disclosure" obligations to the SEC. Introduction For virtually all oil and gas producers, their company assets are the hydrocarbon reserves that they own through various forms of mineral interests, licensing agreements, or other contracts and that produce revenues from production and sale. Reserves are almost always reported as static quantities as of a specific date and classified into one or more categories to describe the uncertainty and production status associated with each category. The economic value of these reserves is a direct function of how the quantities are to be produced and sold over the physical or contract lives of the properties. Reserves owned by private and publicly owned companies are always assumed to be those quantities of oil and gas that can be produced and sold at a profit under assumed future prices and costs. Reserves under the control of state-owned or national oil companies may reflect quantities that exceed those deemed profitable under the commercial terms typically imposed on private or publicly owned companies.

The special mobile diagnostic group (MDG) is formed in the Federal State Budgetary Establishment «33 Central Scientific Research Test Institute» of the Ministry of Defenсe of the Russian Federation (hereinafter referred to as the institute) to perform tasks related to the radiation and chemical (RCh) control of different objects, to ensure RCh safety and security of mass events, as well as to perform special tasks of RCh examination of samples of all kinds. The purpose of the work is to consider the design, capabilities and organization of the mobile complex of chemical control (MCCC), which is the basis of the technical equipment of the MDG. The complex is created on the basis of Ford-Transit off-road vehicle with the equipment for the MDG and a container installed on a two-axle platform, where the equipment for the MDG is located. The complex is equipped with modern analytical equipment, means of communications, navigation, information processing and automatic meteorological observation, with the life support kit, autonomous power and water supply systems, exhaust ventilation, heating and air conditioning systems. The technical characteristics of the MCCC are as follows: crew – 8 people; preparation time – no more than 60 minutes; time for the preliminary identification of substances detected by the mobile group (from the moment of arrival) – no more than 60 minutes; the lower limit of detection of toxic chemicals in environmental objects – at the maximum concentration limit; time of confirming identification of detected toxic chemicals (from the moment of delivery of samples) – no more than 180 minutes; cruising range – up to 700 km. The methodological apparatus is also developed, that ensures the functioning of the MCCC crew during the performance of wide range of tasks of the MDG. Subsequently, this methodological apparatus has been repeatedly expanded and refined based on the results of the complex's participation in ensuring the RCh security of various mass events. The algorithm of carrying out special chemical control by technical means of the MCCC complex is presented in the article. The complex is capable of detecting both low-hazard and emergency concentrations of practically all known toxic chemicals in various samples, and identifying these substances in environmental objects.

The subject of the research within the framework of the article is the criminal procedure institute for the detention of a person on suspicion of committing a crime. The legal nature of this institution is analyzed, and comments are given on the normative legal acts and judicial practice regulating the issues of detention. The theoretical basis of the research is based on the publications of the last two decades on this problem, in particular, reflecting the discussion of the process scientists S. A. Shafer, S. B. Rossinsky and A. A. Tarasov, the subject of which was the issue of the legal nature of a suspect detention in a criminal case. In the paper, the authors ask the following questions: What is the detention of a person on suspicion of committing a crime in accordance with the legislation of the Russian Federation? From what moment does the detained person acquire the status of a suspect? Is it possible to detain a person before initiating a criminal case? The study concludes that a person acquires the actual status of a suspect from the moment of direct detention, that is, before documenting this status and, as a result, before initiating a criminal case. Amendments to the articles of the Criminal Procedure Code of the Russian Federation are proposed, and the authors` versions of the definitions of the concepts «detention of a suspect», «the moment of actual detention» and «pre-trial proceedings» are given.

В статье проведен анализ существующей практики защиты имущественных интересов уголовно-исполнительной системы Российской Федерации при участии в уголовном процессе в качестве представителя потерпевшего, изложены рекомендации по улучшению данной работы с учетом особенностей сложившейся практики. Раскрываются особенности уголовно-процессуальной защиты на основе материалов территориальных органов и анализа дел указанной категории схарактеристикой эффективных решений иимеющихся проблем по защите имущественных интересов уголовно-исполнительной системы (далее - УИС), материалов практики защиты поуказанным вопросам, аналитических и статистических данных за 2018-2020 гг. Обращено внимание, чтона практике имеются сложности с определением размера возмещаемого ущерба и сроков исковой давности, а также с фактическим исполнением судебных решений овзыскании ущерба в связи с финансовой несостоятельностью должников. Важной проблемой по защите имущественных интересов остается отсутствие методики определения размера причиненного репутационного вреда органам иучреждениям уголовно-исполнительной системы Российской Федерации. Обеспечение своевременного допуска представителя органа илиучреждения УИС имеет существенное значение для защиты имущественных интересов, поскольку юридическое лицо получает фактическую возможность по отстаиванию своих законных интересов лишь смомента допуска представителя - физического лица. Автором определены направления работы должностных и иных заинтересованных лиц по реализации защиты имущественных интересов УИС при участии в уголовном процессе в качестве представителя потерпевшего. The article analyzes the existing practice of protecting the property interests of the Penal system of the Russian Federation when participating in criminal proceedings as a representative of the victim, and provides recommendations for improving this work, taking into account the features of the current practice. The article reveals the features of criminal procedure protection based on the materials of territorial bodies and the analysis of cases of this category with the characteristics of effective solutions and existing problems in protecting the property interests of the Penal system (hereinafter the FPS), materials of defense practice on these issues, analytical and statistical data for the period 2018-2020. Attention is drawn to the fact that in practice there are some peculiarities in determining the amount of damage to be compensated and the limitation period. Due to the financial insolvency of debtors in practice, there is a difficulty with the actual execution of court decisions on recovery of damages. An important problem in protecting property interests remains the lack of a methodology for determining the amount of reputational damage caused to the bodies and institutions of the Russian Federation's penal system. Ensuring the timely admission of a representative of a body or institution of a penal system is essential for the protection of property interests, since a legal entity gets the actual opportunity to defend its legitimate interests only from the moment of admission of a representative - an individual. The author defines the directions of work of officials and other interested persons to protect the property interests of the Penal system of the Russian Federation when participating in criminal proceedings as a representative of the victim.

Studies have found that the Permian is another important stratum for petroleum exploration except the Jurassic coal measures within Turpan–Hami Basin recently. However, the knowledge of the depositional environments and its petroleum geological significances during the Middle–Late Permian is still limited. Based on the analysis about the sedimentological features of the outcrop and the geochemical characteristics of mudstones from the Middle Permian Taerlang Formation and Upper Permian Quanzijie Formation in the Taoshuyuanzi profile, northwest Turpan–Hami Basin, this paper makes a detailed discussion on the Middle–Late Permian paleoenvironment and its petroleum geological significances. The Middle–Upper Permian delta–lacustrine depositional system was characterized by complex vertical lithofacies assemblages, which were primarily influenced by tectonism and frequent lake-level variations in this area. The Taerlang Formation showed a significant lake transgression trend, whereas the regressive trend of the Quanzijie Formation was relatively weaker. The provenance of Taerlang and Quanzijie Formations was derived from the rift shoulder (Bogda Mountain area now) to the north and might be composed of a mixture of andesite and felsic volcanic source rocks. The Lower Taerlang Formation was deposited in a relatively hot–dry climate, whereas the Upper Taerlang and Quanzijie Formations were deposited in a relatively humid climate. During the Middle–Late Permian, this area belonged to an overall semi-saline water depositional environment. The paleosalinity values showed stepwise decreases from the Lower Taerlang Formation to the Upper Quanzijie Formation, which was influenced by the changes of paleoclimate in this region. During the Middle–Late Permian, the study area was in an overall anoxic depositional environment. The paleoenvironment with humid climate, lower paleosalinity, anoxic condition, and semi-deep to deep water during the deposition of the Upper Taerlang Formation was suitable for the accumulation of mudstones with higher TOC values.

Facies analysis and depositional environment identification of the Vin field was evaluated through the integration and comparison of results from wireline logs, core analysis, seismic data, ditch cutting samples and petrophysical parameters. Well log suites from 22 wells comprising gamma ray, resistivity, neutron, density, seismic data, and ditch cutting samples were obtained and analyzed. Prediction of depositional environment was made through the usage of wireline log shapes of facies combined with result from cores and ditch cuttings sample description. The aims of this study were to identify the facies and depositional environments of the D-3 reservoir sand in the Vin field. Two sets of correlations were made on the E-W trend to validate the reservoir top and base while the isopach map was used to establish the reservoir continuity. Facies analysis was carried out to identify the various depositional environments. The result showed that the reservoir is an elongate , four way dip closed roll over anticline associated with an E-W trending growth fault and contains two structural high separated by a saddle. The offshore bar unit is an elongate sand body with length: width ratio of >3:1 and is aligned parallel to the coast-line. Analysis of the gamma ray logs indicated that four log facies were recognized in all the wells used for the study. These include: Funnel-shaped (coarsening upward sequences), bell-shaped or fining upward sequences, the bow shape and irregular shape. Based on these categories of facies, the depositional environments were interpreted as deltaic distributaries, regressive barrier bars, reworked offshore bars and shallow marine. Analysis of the wireline logs and their core/ditch cuttings description has led to the conclusion that the reservoir sandstones of the Agbada Formation in the Vin field of the eastern Niger Delta is predominantly marine deltaic sequence, strongly influenced by clastic output from the Niger Delta. Deposition occurred in a variety of littoral and neritic environment ranging from barrier sand complex to fully marine outer shelf mudstones.
