Shale gas is one of unconventional gas resources and stores in organic rich shales and mudstones as free gas and absorbed gas in pores developed in organic matter and mineral matrix. Shale gas accumulation is considered as a cumulative gas charging within organic rich shales, and the organic rich shales serve as gas source, reservoir and seals. The gas origin in shale gas reservoirs could be thermogenic, biogenic or the mixing of both. The feature of low porosity (<10%) and low permeability (μD~nD) in shales requires hydraulic fracturing to enhance pore connectivity for achieving commercial gas production. A success of shale gas development in the United States is a typical model of comprehensive integrating between shale gas geological characterization and petroleum engineering technologies. Shale gas exploration in China is in its early stage but shows a great resource potential. The low-level shale gas survey, immature technologies for shale gas development, unclear understanding of main controlling factors of shale gas reservoirs, the lack of the theory and model of shale gas accumulation are challenging issues for shale gas success in China.
