Mechanisms of helium differential enrichment and helium‐nitrogen coupling: A case study from the Weiyuan and Anyue gas fields, Sichuan Basin, China

Geological Journal, Volume 59, Issue 1, Page 272-287, January 2024.
The uplift of the basement granite was crucial for the exsolution and enrichment of dissolved helium, and it was also the main reason for He–N2 coupling. The differential uplift that occurred in the Leshan–Longnvsi palaeo‐uplift during the Himalayan period further promoted the differential enrichment of He resources, thus also impacting the N2/He ratio

Comparative Analysis of Shale Gas Enrichment and High Yield Geological Conditions of Wufeng–Longmaxi Formation and Qiongzhusi Formation in Southern Sichuan Basin

Geofluids, Volume 2024, Issue 1, 2024.
Wufeng–Longmaxi Formation and Qiongzhusi Formation are the significant shale gas exploration strata in China. The former has made a major breakthrough, and the exploration of the latter is restricted. At present, it shows good exploration potential in the Qiongzhusi Formation.
