The trend of energy development and consumption gradually turns from conventional hydrocarbon to unconventional hydrocarbon. Among the unconventional hydrocarbon resources, gas hydrates bring promise for the greatest amount of hydrocarbon resources that can meet the increasing world energy demand. Natural gas hydrates are solid ice-like structures composed of gas (dominantly methane) and water molecules. Based on the seismic surveys done worldwide, gas hydrates can exist in deep-water, at relatively shallow depths below the sea floor, or at terrestrial locations within and beneath deep permafrost. Hydrates were known more than a century ago. They have been considered as hazards to offshore operation because they may plug the subsea BOP, wellhead, riser, pipeline, etc. Through its huge amount of accumulation, gas hydrates provide the possibility to secure the future energy necessity to replace the present conventional hydrocarbon role worldwide. This paper presents one of research topics conducted in Department of Petroleum Engineering ITB to describe the evolving paradigm of gas hydrates both as problems and future energy resources. The aims of this study are to provide the knowledge of gas hydrates system and the possible methodologies to explore and exploit them. The specific engineering aspects such as GGR (geologic, geophysics and reservoir), drilling and completion, and feasible production techniques are carried on in this research to better estimate the dynamic characteristics of gas hydrates. The fact that gas hydrates often bring forth problems in petroleum industry operation, both in offshore and cold land onshore, has broadened the researchers’ insight of gas hydrate behaviors. The progress researches which vigorously carried on worldwide will be incorporated into this study, coupled with the research and development in Indonesia. It is expected that the result of the study presented herein, can be used as reference in future research and engineering application in Indonesia in terms of gas hydrate development, and henceforward it can support Indonesian energy market.
