China's deepest gas field in marine strata,Yuanba gas field in Sichuan Province, is to be put into operation by year end, energy giant Sinopec announced.
It will produce 3.4 billion cubic meters of natural gas every year, supporting many regions along the middle and lower reaches of the Yangtze River, including Shanghai, Zhejiang, Jiangsu and Anhui, according to Sinopec.
The field's deposits are as deep as 6,700 meters, and it has a total explored reserves of 219.4 billion cubic meters. It is one of the most difficult gas fields to construct due to the high risk.
Sichuan is also home to China's second largest gas field Puguang.
Sinopec started exploring the Yuanba area in 2007 and formally began development and construction of the gas field in 2011. Sinopec Group said in April that the Yuanba field will play a significant role in energy security.
