Development of shale gas in North America has come into commercialized production. China with rich shale gas resourcesstarted lately in developing. Several factors, such as the complicated geological structure and incomplete technology, do influencethe progress of shale gas development. This paper introduce the mature technologies in North America, including the choice offracture fluid, the horizontal well fracturing technology, the monitoring technology in the later period. Bidding exploration rightin earlier stage, infrastructure, environment, are all main points in shale gas developing in China.
