Abstract While the demand for hydrocarbon resources has been continuously increasing in the past 150 years, the industry is, however, criticized for carbon dioxide (CO2) emissions and concomitant global warming concerns. The oil and gas industry also face growing pressures in the ongoing energy transition. Generating and producing hydrogen (H2) directly from petroleum reservoirs has the potential to mitigate environmental impacts while revolutionizing the traditional petroleum industry and enabling it to become a clean hydrogen industry. This paper proposes a novel approach to generate high-purity, CO2-free hydrogen from the abundant oil and gas resources in petroleum reservoirs using microwave heating. In this work, laboratory experiments were conducted to validate this scientific proof-of-concept and examine the roles of crushed rocks, catalysts, and water/oil ratio in hydrogen generation from crude oils in a reactor. A maximum of 63% ultimate hydrogen content is obtained in the generated gas mixtures, while the original CO2content in all experiments is negligible (<1%). Catalysts can promote hydrogen generation by accelerating rate and locally enhancing microwave (MW) absorption to create ‘super-hot spots'. Water also participates in reactions, and additional hydrogen is generated through water-gas shift reactions. The water-oil ratio in porous rocks affects the ultimate hydrogen yield. Overall, this research demonstrates the great potential of using MW heating to generate high-purity, CO2-free hydrogen from in situ petroleum reservoirs. Further research and wide application of this technology would potentially transform petroleum reservoirs to hydrogen generators, thus mitigating the environmental impacts of traditional petroleum industry while meeting the increasing demand for clean hydrogen energy. This technology would also benefit the safe transition towards a decarbonized society.

Russia’s evident ‘turn to the sea’ as regards the economy, the infrastructure, and population distribution patterns is very much in line with the interests and projects of large businesses. This change manifests itself in the development of port and logistics complexes, the port industry, the construction of offshore pipelines, more active offshore oil and gas production, the growing demographic potential of coastal cities, etc. This article aims to explore the localisation of large businesses in Russian coastal zones and to analyse the ‘coastalisation’ of the country’s largest companies. It is shown that ‘coastalisation’ has taken place in forty-two of Russia’s top 100 companies, as rated by the Russian Business Channel. Another objective of the study is to identify large businesses’ industrial and regional priorities in the maritime economy and investigate how they are transformed under the influence of geopolitical and geo-economic factors. Amid active Eurasian integration, which includes the Greater Eurasia project, big businesses are spurring the development of maritime economic complexes and the formation of sea-land economic structures, including cross-border ones. The study identifies which national coastal zones are most attractive to Russian large businesses. Special attention is paid here to the Baltic Sea and the exclave of Kaliningrad where both local (Sodruzhestvo and Avtotor) and interregional/transnational companies (United Shipbuilding Corporation, Gazprom, LUKOIL, etc.) are benefitting from the coastal factor in the socio-economic development.

The paper deals with analysis of the geochemical and NMR characteristics of oils from a number of fields in the West Siberian oil and gas province. The group composition of the studied samples was estimated by NMR data. The correlation with the results of geochemical analysis was established.
