Discussion on the natural gas development that includes unconventional gas in China

At present, the main energy resources in the world are oil, natural gas, coal, uranium, etc., which are commonly referred to as conventional energy resources. Otherwise, resources called unconventional energy resources are predicted to have enormous potential exists. Among the unconventional energy resources, as corresponding to the natural gas, these include shale gas, coal bed methane, tight gas, methane hydrate, water-soluble gas, and others. In recent years, owing to the advances in technological development, research and development of unconventional natural gas have been activated. In particular developed, such as shale gas in North America, will have a great influence on the gas supply in the world in the future.
