Characteristics of shale gas

Characteristics of shale gas
Shale gas development with mining long life and long production cycle advantages - most gas shales wide distribution
Thickness, and generally gas, making shale gas wells to long-term stability of gas production. But  shale gas  reservoir permeability is low, mining difficult. With the world's energy consumption continues to rise, including shale gas, including  Unconventional gas  more and more attention. United States and Canada and other countries have achieved shale gas commercial exploitation. Shale gas reservoirs with generally showed low porosity and low permeability material characteristics, resistance to airflow than conventional natural gas large, all of the wells need to implement reservoir fracturing to be mined on the other hand, shale gas mining yield than conventional natural gas is low, conventional gas recovery above 60%, while the shale gas is only 5% to 60%. Low-yielding influence people to its enthusiasm, and now the United States have some of the advanced technology can improve  shale gas  production. China shale gas reservoirs compared with the U.S. is different, such as the Sichuan Basin shale gas depth than the U.S. large, U.S. shale gas depths of 800 to 2600 m, and the Sichuan Basin page rock gas buried in 2000 to 3500 meters. Shale gas reservoir depth increases undoubtedly in our present immature technology has added a degree of difficulty.
