Characteristics of Pyrite in Shale and Its Application in Shale Gas Enrichment Evaluation─a Case Study of Longmaxi Shales in the Xiang’exi Depression, China

Abstract: Exploration and development of shale gas in China have made significant breakthroughs in recent years. Longmaxi shales in the Xiang'exi depression are the key targets for shale gas exploration in the middle Yangtze region. However, systematic studies on the authigenic minerals and their application in shale gas enrichment evaluation are insufficient. Therefore, in this study, pyrite was selected to characterize its morphology, grain size, and distribution characteristics, with the hope to identify the favorabl… Show more

“…As a widely distributed, efficient and clean gas energy, shale gas has been the key study direction of China’s energy development strategy in recent years. Block H in western Hubei-eastern Chongqing is a crucial area for shale gas development in Hubei province, and its Wujiaping Formation shale is the shale gas reservoir with the most exploration potential after the large-scale commercial development of Wufeng-Longmaxi Formation in Sichuan Basin. The Wujiaping Formation in this area is characterized by high organic abundance, moderate maturation, and favorable preservation conditions, and has attracted considerable attention from numerous domestic oil companies . Sinopec and PetroChina have carried out exploration and development plans targeting this strata.…”

“…China has made notable progress in the exploration and development of shale gas, with shale gas production has surpassing 220 × 10 8 m 3 by 2021, establishing it as the second-largest shale gas producer globally [1][2][3][4]. China possesses enormous potential in shale gas resources, particularly in deep-sea shale reservoirs, marine-continental transition zones, and continental shale systems, showing significant exploration and development opportunities [5][6][7][8].…”
