A high-yield oil and gas flow was discovered in the Daye 1H exploration well in the Liangping District of southwest China's Chongqing. The exploration well obtained a daily output of 320,600 cubic meters of shale gas during testing.

The explorable area is more than 2,885 square kilometers at a depth of up to 5,000 meters, and the total reserve volume is estimated to be 1 trillion cubic meters. Shale gas is a kind of natural gas stored in shale rocks, which has a long mining life and high industrial economic value.
