State-controlled Sinopec on Thursday said it added 83 billion cubic metres (2.93 trillion cubic feet) of proven reserves at Chuanxi. The new reserves, which have been certified by China’s Ministry of Natural Resources, increases the field’s total proven reserves to 114 Bcm of gas.

The field’s key reservoirs that extend over 138 square kilometres in the western part of the Sichuan basin, are located at a subsurface depth of 6000 metres and are high in acidic content, Reuters reported Sinopec as saying.

Sinopec last week announced it had achieved China’s highest ever daily production of shale gas — 20.62 million cubic metres — at its Fuling field in Chongqing, China.

The Fuling shale gas field currently maintains stable output of 20 MMcmd and will produce an estimated 6.7 Bcm of shale gas per annum.
