Enrichment and Exploration Potential of Shale Gas in the Permian Wujiaping Formation, Northeastern Sichuan Basin
Year: 2025
Type: article
Abstract: The high-yield industrial gas from Sichuan Basin’s Wujiaping (P3w) shale reveals a new unconventional exploration play. Due to the strong heterogeneity of shale gas, its enrichment and exploration potential remain unclear. Geochemical and other experiments conducted on this layer have shown that: (1) The third member of the P3w (P3w3) shale has optimal quality, with large thickness and wide distribution. The average TOC value is 6.09%, and the organic matter type is II1~II2. (2) Shale gas in the P3w is supplied by organic-rich shale; enrichment is promoted by siliceous/clay shale interbedding, with storage in organic matter pores and fractures. (3) Comparative analyses with the Wufeng–Longmaxi shales (O3w-S1l) show that P3w3 is the layer with the greatest potential for shale gas exploration.
