Qaidam Basin
China's onshore oil resources are mostly located in the Northeast and in Xinjiang, Gansu, Qinghai, Sichuan, Shandong, and Henan provinces. Oil shale is found in a number of places, especially at Fushun in Liaoning, where the deposits overlie the coal reserves, as well as in Guangdong. High quality light oil has been found in the Pearl River estuary of the South China Sea, the Qaidam Basin in Qinghai, and the Tarim Basin in Xinjiang. The country consumes most of its oil output but does export some crude oil and oil products. China has explored and developed oil deposits in the South China Sea and East China Sea, the Yellow Sea, the Gulf of Tonkin, and the Bohai Sea.
