“…Combined with a selection indicator evaluation system for potential storage sites, the standardization of the CCS in China has a good foundation [20,21,113,114]. A preliminary evaluation of the CO 2 storage potential in the saline formations at a depth of 1-3 km showed a capacity of 1.435 × 10 Table 1. the studies on CO 2 sequestration in saline formations [117][118][119][120][121][122][123][124], the first full chain CCS project in China was successfully launched in the Ordos Basin with a storage target of 0.1 million tons of CO 2 injected in 2010 [125][126][127][128][129][130]. about 70% of the oil production comes from nine oilfields, that is, Changqing, Tarim, Daqing, Shengli, Yanchang, Bohai, Liaohe, Zhongyuan, and Jilin.…”
