scholarly journals Introductory remarks to the third session

This is a critical time in the history of diving and, in particular, a critical time for research into the effects of raised environmental pressure. Two principal reasons for the present situation are that diving appears to be approaching the natural limitations imposed by depth, and that diving has already exceeded the depths at which it can attract naval research funds. However, for selected tasks, and until the robots and one atmosphere alternatives become totally reliable, there will continue to be a task for man to the maximum depth of oil and gas production. The ultimate depth limit to be imposed upon man’s ability to work in the sea has not been defined and may not necessarily be one that is biological in nature. Possibly it will be a financial limit. One reason for this is the large cost of the resources that are required at sea to support a man more than 400 m below its surface.

The relevance of this study is due to the need to optimize the physical activity of workers engaged in heavy physical labor, which is impossible without taking into account their physical culture and sports preferences. The aim of the study was to identify the physical culture and sports preferences of employees of oil and gas production enterprises, as well as factors that characterize the features of their motor behavior and body functioning. To analyze the subjects' physical culture and sports preferences and features of physical activity, a survey was conducted; the Attitude to Competitive Physical Culture and Sports Activities questionnaire was used; the heart rate variability was studied using the hardware and software complex “Omega”. The significance of the difference in the characteristics in the compared groups was verified using the Mann-Whitney U-test. The study involved 49 men of mature age who are engaged in professional activities at oil and gas production enterprises, using out-of-hours means of physical culture and sports of a recreational or sports orientation. The subjects were differentiated based on their physical culture and sports preferences, depending on the manifestation of rivalry in them: 1) with individual rivalry (n1=19); 2) with team rivalry (n2=15); 3) with avoiding open rivalry (n3=15). All the men who prefer martial arts did sports in the past or continue to do sports in the present. Of those who prefer team sports, this is 80%, and of those who avoid open competition, preferring individual running, recreational walking or strength training, this is 54%. All representatives of the first group systematically engage in physical culture and sports. Thirty-three per cent of men who prefer activities without rivalry and seven per cent of men doing team sports do sports from time to time. Subjective readiness to participate in physical culture and sports events is more evident in men who prefer martial arts. To a lesser extent, men from the third group are ready to participate in events with the manifestation of maximum physical capabilities. The indicator that characterizes the interest in knowledge in the field of physical culture and sports, as well as the activity of attracting other people to participate in competitions, prevails among men who prefer martial arts. The most optimal indicators of the activity of regulatory systems are observed in men who prefer team sports. In subjects who engage in martial arts in their free time, the indicators of the autonomic regulation of the heart are also within the normal range, but closer to the border that characterizes the transition from the vegetative balance to the predominance of the sympathetic department. In the representatives of the third group who refuse open competition and prefer individual activities, there is a more pronounced tension of the regulatory systems. The results obtained should be taken into account when developing corporate programs to optimize the physical activity of employees of oil and gas producing enterprises.

Кратко рассмотрена история создания искусственных островов в мире и в России. Проанализированы задачи, возлагаемые на искусственные острова, существующие технологии их строительства. Особое внимание уделено экологическим проблемам, возникающим при строительстве и эксплуатации островов. Сделан вывод о том, что в настоящее время в России наиболее перспективно создание искусственных островов для развития транспортной и портовой инфраструктуры, нефтегазодобыче на морском шельфе. Разработанные в настоящее время технологии позволяют создавать искусственные острова в самых разных природных условиях. Лимитирующими факторами являются рентабельность и возникающие при строительстве и эксплуатации экологические проблемы. The article provides brief review for history of artificial islands creation in Russia and around the world. It includes analysis of tasks assigned to artificial islands and existing technologies of their creation. Special attention is focused on ecological questions arising during their construction and maintenance. The article concludes that the most actual artificial islands are constructed for transport and port infrastructure development and oil and gas production on the shelf. Modern technologies allow creation of artificial islands in different nature conditions. Economical efficiency and ecological questions are restriction factors for artificial islands creation and maintenance.

New petroleum paradigms in mature basins can be derived from re-examining geological parameters without bias of preceding theory. Kansas has a long history of oil and gas production with over 300,000 wells drilled. Precambrian basement faults in Kansas control the development of later structures, and probably, reservoirs. This study and re-interpretation of geologic history has identified a possible new play along reverse and thrust faults of the Humboldt Fault Zone along the eastern margin of the Nemaha uplift. This paper also suggests that the lack of significant petroleum production in the Salina basin is the result of migration barriers created by faults at the junction of two major fracture trends, rather than by limited local generation and migration.

The Surkhandarya region is one of the five petroleum bearing regions of the Republic of Uzbekistan, with proven oil and gas production in the stratigraphic range from the Middle Upper Jurassic to the Upper Paleogeone, inclusive. The article provides a general overview of the region, the history of geological and geophysical exploration, lithological and stratigraphic characteristics of sections, tectonic structure, oil and gas content. The stratigraphic and tectonic confinement of accumulations and their phases composition are given. The history of the development of the region is considered, the results of geological petroleum exploration, including those carried out by investors, the number of petroleum discoveries, their ranking by types of fluids, and the degree of development are presented. The priority stratigraphic structures and territories for further petroleum exploration have been identified. Further oil and gas prospects of the region are justified by the presence of promising traps, as well as predictedand promising hydrocarbon resources. The forecasted resources of hydrocarbon raw materials are given for stratigraphic sections: Middle-Upper Jurassic, Lower Cretaceous, Upper Cretaceous and Paleogene age, which indicates the expediency of carrying out prospecting petroleum exploration in the Surkhandarya region of the Republic of Uzbekistan.
