Sažetak
Natural methane hydrates have been discovered 40 years ago and since then there have been intensive investments in research and development of techniques and technologies for their exploration and production. Today, with the high prices of oil, resulted from depletion of conventional hydrocarbon reserves and constant increase of global energy demand, unconventional energy resources, such as methane hydrates, are becoming even more researched and invested in. Due to specific thermodynamic conditions of their stability, the methane hydrate deposits are limited to permafrost and deep ocean areas. Total amount of methane in methane hydrates is high. Seafloor stability is often disturbed by the existence of methane hydrates in seafloor sediments. Because of that, drilling through methane hydrate geological formations poses high risk to drilling operations and hence should be taken into consideration through planning of offshore petroleum activities. Till today there have been large investments into research of methane hydrates not only for natural phenomena of their existence, but due to possibility of their exploitation. In this paper the present discoveries about their forming, natural deposits, methods of exploration and their impact on the environment and global climate change are presented. The special emphasis has been put on challenges and problems of their possible commercial production.
