To analyze Australian methane hydrate resources, exploration, and production, its current state and future potential.Methods. Analysis of data published in different sources concerned with geological surveys and government reports related to Australian natural gas reserves, production and consumption of gas in Australia. Analysis of theoretical and experimental research into methane hydrates properties and prevention of gas hydrate deposits formation in pipes during production and transportation of natural gas.Findings. The study of gross figures associated with the present state of gas production in Australia testified that enough gas is extracted to meet the current needs. Increase in natural gas consumption in future creates good chances for developing gas production from unconventional deposits, specifically getting methane from gas hydrates deposits. While predicting main trends in the efficient exploration and use of methane hydrates resources it is necessary to consider their possible impact on the environment.Originality. On the basis of the conducted analysis, the current state of methane hydrates research in Australia is examined. For its gas industry, it is critical to estimate their reserves and assess methane extraction from gas hydrates deposits in the near future. Practical implications.The obtained results can be used to evaluate the investment attractiveness of future exploration of methane hydrates resources in Australia.

Conceptual principles of project management for development of hydrate and other unconventional gas fields as a component of energy security of Ukraine

“…The shift in the focus of offshore oil and gas development from coastal to mediumdepth and deep-water areas, with the use of new technologies such as horizontal offshore drilling and floating platforms, allows for the development of gas hydrate deposits [9]. Among the technological achievements of recent years, technologies of multi-stage fracturing come to the fore, which allow to effectively develop gas deposits in shale and tight rocks.…”

“…The phased implementation of the tasks of the New Energy Strategy of Ukraine "Security, Energy Efficiency, Competitiveness" in the context of the implementation of the Sustainable Development Strategy until 2030 [7], will require the implementation of appropriate large-scale investment projects and programs. Taking into account the main features of the project activity in the development of gas hydrate fields, the modern methodology of project management allowed to identify several main features of project identification of the project concept development phase, in particular [8,9] -in terms of implementation -long-term, more than 3 years (the second and third stages of reforming the energy sector -"Optimization and innovative development of energy infrastructure" (until 2025) and "Ensuring sustainable development" (until 2035)); -in scale -large; in terms of complexity -complex and very complex megaprojects as complex infrastructure projects for the development of the gas sector of the economy, consisting of mono-and multi-projects and today require professional multi-project management based on modern methodology of project-oriented management.…”

Mining of methane from deposits subaquatic gas hydrates using OTEС

“…Therefore, if such a complex will be built in the conditions of possible use of OTEC, for example in the water near Black Sea [18] or in the Australia [26], it is advisable to generate electricity for energy production in a separate plant using OTEC gas hydrate cycle technology (GHET), in which working fluid is methane, which is extracted. Such a plant can be placed on the same platform 4 with a plant for extracting methane from subaquatic deposits of gas hydrates.…”

Effect of mechanoactivated chemical additives on the process of gas hydrate formation

“…The study of properties of clathrate hydrates is necessary for improvement of modern technologies for gas production and gas transportation from gas hydrate deposits, creation of energy-saving technologies, development of hydrocarbon energy and technologies for separation of gas mixtures [29,30]. A subsequent study of gas hydrate technologies and their application in practice is impossible without a detailed study of the kinetics of hydrate formation.…”
