Sinopec strikes sizeable gas flows from deep coalseam well in Chongqing
China’s Sinopec Corp 0386.HK said on Wednesday it has achieved an average daily gas flow of 12,000 cubic metres from a coalseam methane well in southwestern Chongqing municipality, marking a breakthrough in exploring deep coalseam gas reservoirs.
The Yang-2 well, with a depth of over 1,900 metres, has produced 1.2 million cubic metres of coalbed methane in the past 100 days, Sinopec said in a statement.
The coalseam gas reservoir is trapped between 500 metres and 3,000 metres below surface.
China’s national energy giants have in recent years been investing more to tap deeper and harder-to-extract hydrocarbon resources such as shale oil and shale gas to boost domestic supply.
