(Yicai Global) Oct. 8 -- China's total shale gas output has reached 20 billion cubic meters since production began in 2015 at the Fuling field in the western municipality of Chongqing.

Output at Fuling, the world's biggest shale field outside of North America, will reach 10 billion cubic meters this year, state broadcaster CCTV reported, adding that the site boasts some 600.8 billion cubic meters in proven reserves.

The field provides clean energy to six provinces and two municipalities along the Yangtze River via the Sichuan-to-East gas transmission pipelines with daily output enough to satisfy up to 32 million households.

China aims to achieve 30 billion cubic meters in accumulated shale gas output by 2020 and between 80 billion and 100 billion cubic meters by 2030, the National Energy Administration stated in September 2016.
