米国シェールガス探鉱・開発

―地質からのアプローチ―

抄録

Shale gas production in USA has grown rapidly in recent years. The detail production mechanism from shale rock is still not clearly investigated since it has a relatively short production history. This paper shows summary of shale gas exploration and development, project evaluation method and geological approach to understand shale evaluation based on public information. Various geological feature of unconventional play should be considered for the geological evaluation. Furthermore unexpected problems for shale gas development are shown, which came up with the growth of development and production activities in USA.
