A key development of the Sichuan and Chongqing Natural Gas Base-Deep Earth Project, Phase I of the Bazhong gas field adds 30.55 billion cubic meters of proven geological reserves.

CHONGQING, China, August 23, 2023/PRNewswire/ -- China Petroleum

The Bazhong gas field is the third Xujiahe Formation tight sandstone gas field discovered by Sinopec in the region. So far, Sinopec has presented a total of 154.747 million cubic meters of proven geological reserves of tight gas in the region.

The sandstone gas reserve with a burial depth of more than 4,500 meters is defined as an ultra-deep and compact sandstone gas reservoir, and the burial depth of the Bazhong gas field ranges from 4,550 to 5,225 meters, which is a challenge for exploration and development. Sinopec has innovated three kinds of high-quality reservoir and permeability development models to clarify natural gas enrichment and high-yield production models, established sequences of reservoir prediction techniques, and implemented high-yield enrichment zones.

Next, Sinopec will continue to undertake the process of engineering and geological evaluation of the shale gas reserves in the Sichuan Basin to expand the scale of the reserves in the Bazhong region.
