Risk factors for Oil and Gas Workers on the Offshore Ice-Resistant Platform in the Caspian Sea (Russian)

For almost three centuries, starting with the campaign of Peter the Great in 1721-1722, Russia has traditionally played a key role in the Caspian Sea. The situation changed dramatically with the collapse of the USSR in 1991 and the emergence of three new regional players-Azerbaijan, Kazakhstan and Turkmenistan. For Russia, this meant a significant reduction in influence in the region and the loss of control over most of the water area and the sea and its resources. In the historiography devoted to the region, the emphasis is placed on assessing the new round of geopolitical struggle, the position and interests of Western and regional powers. The author of this article provides a critical analysis of changes in Russian policy towards the Caspian Sea over the past 30 years and assesses the effectiveness of these changes. The difficult transition from the role of a dominant player in a region closed to external competitors to an open geopolitical confrontation over resources, their transportation routes, and political influence at the first stage was not in favor of Russia. Russia could not defend the principle of a condominium for joint development of hydrocarbon resources of the sea. With the active assistance of Western competitors, Russia lost its status as a monopoly transit country for oil and gas from the region. At the same time, thanks to diplomatic efforts and increased political dialogue with its neighbors in the region, Russia managed to resolve all territorial issues at sea by 2003, maintain the closed status of the sea for the military forces of third countries, and by 2018 complete work on the Convention on the international legal status of the sea, which established the principles of cooperation in the region that are important for the Russian Federation. Thus, official Moscow managed to achieve the strategic goals adapted after the collapse of the USSR by using the traditional strengths of its foreign policy and consolidate its status as the most influential player in the region.

Hydrogeological Characteristics

Hydrogeological conditions of reservoir waters of oil and gas fields in the northern water area of the Caspian Sea characterize the geological features of the structure of the Northern Caspian shelf, as well as the thermodynamic parameters of the exploitation of productive deposits, production and transportation of oil and gas. Reservoir waters contain water-soluble gases. According to the size of mineralization, the ratio of the main components of the salt composition, as well as the presence of iodine and bromine, reservoir waters can be attributed to a relatively "young" genetic age, subject to secondary geochemical processes of changing the salt composition in interaction with "secondary" migrated hydrocarbons. The physical and chemical properties of reservoir waters are determined by PVT analysis technologies. Hydrogeological and geochemical studies of compatibility with reservoir waters of marine waters injected to maintain reservoir pressures (PPD) during the development of offshore fields in order to increase the oil recovery coefficient (KIN) indicate the absence of colmating secondary sedimentation in mixtures of natural and man-made waters.

Inland Water Body

<p>The Caspian Sea is the largest inland water body on the Earth and a unique object for analysis. It is of great importance for the socioeconomic development of bordering countries. Unique fish resources and oil and gas fields are projected to provide a significant source of food and economic prosperity to the Caspian region, as well as energy to many parts of the world. National and transnational oil and gas corporations are involved in the utilization of the commercially attractive Caspian natural resources. The Caspian Sea has been influenced by climate change and anthropogenic disturbance during recent decades, yet the scientific understanding of this water body remains poor. Climatic variability of water circulation in the Caspian Sea remains unclear. Traditionally, currents in the Caspian Sea have been investigated by numerical methods. Instrumental observations of the currents in the Caspian Sea are mostly carried out in the shelf zone. Available data cover very short periods and reflect variability only in synoptic and higher frequency of the sea dynamics. In this work, water velocity data based on SeaHorse equipment is under consideration. Three stations were in northern Caspian, area adjacent to Jayik (Ural) River delta. In both cases, the instruments were deployed in 2016 and 2017 at the point 46.782N, 51.384E, depth about 3 m. In this work, we will present the preliminary results of our study of the field observations we gathered in these points. We also present the analysis of the potential drivers for the spatial and temporal patterns of the measured currents velocity.</p>

The Black Sea is one of the most important geostrategic enclaves in the oil and gas connection linking Asia with Europe and Russia. However, the presence of Turkey on the Bosphorus Strait directly affects how the geo-strategic interactions of the region develop. The crisis in Ukraine has spurred Turkish-Russian relations, positioning the country as a key player in the gas transit to Eurasia and projecting the aspirations of the Kremlin, under President Vladimir Putin has sought to regain an influential weight in the region - as shown by the crisis in Georgia or, more recently, Crimea - especially in the Black Sea and the Caspian Sea. Thus, the following work seeks to put a little light on new relationships and geopolitical aspirations, especially in Russia and Turkey and, likewise, have a direct impact on the European context.

Oil And Gas Resources

The Caspian Sea is the largest body of water in Eurasia: After the collapse of the USSR, the water area of this region is a zone of interest for many states. [1] The Caspian region rightfully serves as one of the most significant regions for most countries interested in the mineral resources that the Caspian is rich in. The Caspian Sea has a significant hydrocarbon reserves. According to the Energy Information Administration (EIA), hydrocarbon resources in the Caspian basin have the following values: oil - 48 billion barrels of oil, natural gas - 292 trillion. cubic feet (found and probable reserves), of which 75% and 67%, respectively, are produced or may be produced offshore. The northern part of the Caspian Sea contains most of the oil reserves, while the southern sector of the Caspian Sea is rich in natural gas.[2] It should be emphasized that the list of states that have the rights to use the resources of the Caspian Sea is as follows: Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan. It is impossible to correlate the importance of the oil and gas resources of the Caspian reservoir for each of the above countries, for the following reasons: Azerbaijan and Turkmenistan are countries for which the hydrocarbon potential of the Caspian is the most important predictor of the formation and development of the economy, while for Kazakhstan, the use of oil and gas resources of the Caspian Sea plays an important , but not the most decisive role, since oil and gas deposits in this country are not limited to the Caspian region, but its economy is developing in other directions. Iran and Russia, however, are interested in influencing the direction of flows of oil and gas raw materials, including their transit through the territory of the countries. [3] The last years for the Caspian region have become the years of a shift in the development of the oil and gas industry of the Caspian "five", which account for 17.6% of oil reserves and 46.4% of gas reserves in terms of global reserves. It is assumed that on the territory of the Caspian shelf, which belongs to Russia, oil reserves amount to 270 million tons, natural gas reserves - 0.5 trillion cubic meters. m of gas. [4] Of course, it is worth noting that the potential of the Russian sector of the Caspian Sea is significantly lower than the oil and gas potential of Yamal or Western Siberia, but the development of this region is important for the strategic development of the oil and gas sector, in particular offshore drilling.

Remote Sensing Methods

By remote sensing methods natural oil seeps and their sources in the southern part of the Caspian Sea off the coast of Iran and in the Barents Sea are studied. It is shown that with the help of a geoinformational approach and additional geological-geophysical information and bathymetric data, it is possible not only to determine their actual position at the bottom, but also to obtain information on their activity, e.g., frequency, volumes of emitted oil, and oil and gas deposits. In addition, this approach allows discovering new seep sources in various seas. It is concluded that the SAR data of the European Sentinel-1 satellites is an excellent material for monitoring and studying natural oil seeping through the observation of oil slicks floating on the sea surface.
