Reuters: Tight Gas: China's unsung unconventional energy revolution

At the heart of the vast desert region of Inner Mongolia, half a dozen young engineers from PetroChina watch huge, flat screens in a brightly lit central control office that oversees 5,000 wells at China's largest gas field.

Just a few years ago, two workers travelling in a truck would need three days to check conditions at 50 wells at the Sulige field, which spans 20,000 sq km (7,700 sq miles) in the middle of Maowusu, China's third-largest desert: now, the task can be done in just five minutes.

Remote Sulige, which means "uncooked meat" in Mongolian, is testament to China's success in developing its giant reserves of so-called "tight gas", part of a drive to dramatically boost consumption of cleaner burning natural gas to help replace dirty coal and costly oil imports. MORE
