China Petroleum & Chemical Corp. (Sinopec) received official certification for the 30.55 billion cu m proven natural gas reserves discovered in Phase I of its Bazhong gas field in northeast Sichuan, China.
Bazhong is the third Xujiahe formation tight sandstone gas field discovered by Sinopec in Sichuan basin. As of now, Sinopec has submitted a total of 154,747 million cu m of proven geological reserves of tight sandstone gas in the region.
Burial depth of Bazhong field ranges from 4,550 to 5,225 m and is defined as an ultra-deep, tight sandstone gas reservoir. Sinopec has innovated three types of reservoir and permeability development models to clarify natural gas enrichment and high-yield production models, the company said.
Sinopec will continue to tackle the geological evaluation and engineering process of the tight sandstone shale gas reserves in Sichuan basin to expand the scale of reserves in the Bazhong region.
