China's state-owned giant oil company Petro China found a major oil field in the Junggar Basin in the Xinjiang Uygur autonomous region late Monday, according to China International Radio news.
The oil reserve is one of the biggest oil fields in the world, according to the report.
The discovery has the potential of having another one-billion tons of reserves, Xinhua reported Tang Yong, a geologist with PetroChina as saying.
Petro China produced 1.38 million tons of oil in this region in the last two years and plans to produce 6 million tons oil between 2016 and 2020.
