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

A Case Study on Preservation Conditions and Influencing Factors of Shale Gas in the Lower Paleozoic Niutitang Formation, Western Hubei and Hunan, Middle Yangtze Region, China

Geofluids, Volume 2024, Issue 1, 2024.
The Niutitang Formation of the lower Cambrian (Є1n) is a target reservoir of shale gas widely developed in China’s Middle‐Upper Yangtze region, with the characteristics of being widely distributed, having a big thickness and highly organic carbon abundance. However, the exploration and research degree are relatively low. Based on extensive core sample,
