The article touches upon the problem of technogenic risks arising in the course of building and operating oil and gas complexes in the Caspian Sea taking into account the adoption of the Con-vention on the legal status of the Caspian Sea and regulation of the territorial division of the Caspian Sea. Technological risks are presented from the position of safety of industrial facilities in the offshore area and in the coastal zone, the impact of these facilities on the ecology of the Caspian is considered. The risk analysis was carried out taking into account world experience, as well as incidents that occurred at the offshore oil and gas production facilities in the Caspian Sea. There has been presented the layout of oil and gas fields at the bottom of the Caspian Sea and the division of the bottom based on adopting the Convention. A general description of the Caspian Sea has been given; unique features of the Caspian and the most unexplored seismic effects have been stated. It has been recommended to conduct a comprehensive assessment of the state of the seabed according to seismological, mud, volcanic and engineering-geological conditions; to develop measures for preventing and reducing the damage from hazardous natural processes and exploitation of oil and gas fields; to forecast the fluctuations of the Caspian Sea level, taking into account today’s economic activity; to study the natural and technogenic factors determining the environmental safety of the Caspian Sea; to monitor seismic phenomena, crustal movement in zones of tectonic faults at the sea bottom, etc. The speed and direction of wind currents in the Caspian Sea have been analyzed. The maps of mud volcanoes location in the Caspian basin (located on land, hidden and identified by seismic, geological, geophysical and geochemical methods, etc.) are illustrated. Conclusions are made about the high risks for developing hydrocarbon deposits in the Caspian Sea basin. There is the need to take into account environmental requirements and standards, to use modern technologies, to prevent incidents at offshore oil and gas production facilities.

Decommissioning offshore oil and gas production facilities have been progressively increasing the concern of the industry, government and other interest groups through the last years. There are at least two reasons for this sudden regard. First, it is the maturing of several oil and gas fields around the world in recent years. Second, it is the growing impact of environmental concerns in international affairs. Despite several works published address to some techniques and to potential problems and risks related to decommissioning offshore oil and gas production installations its procedures are in some extent an innovative issue, especially in Brazil. Therefore, the motivation of this paper is the novelty of the subject in Brazil, since the national industry is just beginning to deal with the end-of-leasing obligations, which involve decommissioning operations. The main ambition is to stimulate debate about appropriate issues.

According to forecast estimates, the depletion of continental oil and gas fields of the Russian Federation is 30 - 50%, and the fields of the continental shelf are less than 1%. Therefore, the main volumes of growth of reserves, oil and gas production in the fuel and energy complex system should be planned at the expense of resources and reserves of the continental shelf. The article considers the principal features of development of oil and gas fields of the continental shelf and criteria determining types of offshore oil and gas fisheries.

The article presents a detailed analysis of the technogenic risks in building and operating oil and gas complexes in the offshore area of the Caspian Sea and actualizes the problem of the Caspian environmental crisis, the possible measures for preventing and minimizing the negative consequences from the extensive offshore oil and gas production for the ecosystem being considered. The geothermal regime of the ground of the Caspian Sea has been analyzed in respect of the deep-earth processes. The bottom of the Caspian Sea is rather varied, hence, the risks for constructing facilities in the area under development are possible. The surface, underwater and island mud volcanoes formed by the large longitudinal and transverse tectonic disturbances pose a threat to oil production and transportation facilities. The tectonic processes of the bottom of the Caspian Sea are studied in detail. It has been stated that the global geodynamic processes are taking place in the earth's crust of the region affecting the natural environment of the Caspian Sea, which will inevitably affect the industrial objects on the shelf. The Caspian Sea ground is divided into two parts in terms of seismic activity: the seismically inactive northern part (the Scythian-Turanian platform and the East European platform) and the southern part (alpine orogenic-folded belt) that is currently seismically active. The diagrams of possible earthquakes and seismic activity in the bottom area of the Caspian Sea are presented. Since the mechanism of the developing seismic activity caused by volcanoes is not fully examined, there has been substantiated the need to prognose precisely the location of hazardous zones and joints in connection with the development of the oil and gas industry. The tectonic and geological frame of the Caspian region has been illustrated; the regional fractures that influence the formation of biosphere zones and the largest tectonic joints that affect natural and man-made processes are noted. Particular attention is paid to the risks of the hydrogen sulfide pollution of the Caspian Sea. Conclusions are drawn about the prospects for the development of the Caspian, which is rich in oil and gas reserves; on the need to ensure safety and reduce losses in the ecological system of the Caspian Sea.

Production units located in the Brazilian marine environment are responsible for the production of 95.7% of oil and 78.8% of natural gas of Brazil causing economic, environmental, and social impacts motivating us to construct a system of indicators as a tool aimed to improve the sustainable management practice of these production units. To date, one of the tools most used by the oil industry is the sustainability report, oriented by guidelines from international organizations. However, these reports have a corporate character being unable to help the sustainability management of production units’ activities. The indicators were selected based on a systemic approach, using current knowledge on sustainability indicators, together with the survey of aspects relevant to the operation and management of offshore oil and gas production units. This paper describes the proposed indicators and presents the hierarchical structure of the system, built on the economic, environmental, social, and operational dimensions. The application of the proposed system of indicators, based on multicriterial and multiple decision-making analyses, validates a complex decision process, providing improved sustainable management of offshore production units by identifying points for which the necessary measures and actions can be implemented. Keywords: offshore oil and gas production; sustainability indicators; multicriteria and multiple decision-making analyses.
