History
In 2015, the CNPC announced the discovery of 100 million metric tons of tight oil geological reserves in the Changqing field (733 million barrels of oil). It was the largest discovery of tight oil in the history of China.[5]
In 2020, it passed the 60 million ton mark in annual production (24.52 million tons of crude oil output). 50 cities in China rely on this oil field. By 2020, Changqing had also produced a total of 468.6 billion cubic meters of natural gas.[4][6] In 2013, Changqing had passed the 50 million mark in annual production (23.58 million tons of crude oil).[7]
