Geological difference and its significance of marine shale gases in South China

Petroleum Exploration and Development, 2016
Organic-rich marine shales are developed in both the Cambrian Qiongzhusi Formation and the Ordovician Wufeng Formation–Silurian Longmaxi Formation in South China, but are different in the drilling results of shale gas exploration.

Organic Matter of the Wufeng–Longmaxi Formation Shales Using Scanning Electron Microscopy

Sustainability, 2023
Fine-grained organic matter (OM) particles are commonly widely dispersed in shale deposits. However, carrying out investigations of pores hosted by OM particles and the nature of grain interactions in OM particles and associated detrital grains using optical microscopy is difficult at best.

Reservoir heterogeneity of the Longmaxi Formation and its significance for shale gas enrichment [PDF]

Energy Science & Engineering, 2020
AbstractTo better determine the sweet spot in the vertical profile of the Longmaxi Formation, the shale heterogeneity was systematically investigated. A series of experiments were conducted on 40 shale samples collected from the Lower Silurian Longmaxi Formation in the Weiyuan shale gas field.

Pore Characterization of Pyrite in the Longmaxi Formation Shale in the Upper Yangtze Area of China [PDF]

Frontiers in Earth Science, 2022
Pyrite is widely distributed in the Longmaxi marine shale in the Upper Yangtze area of China. Pyrite, one of the important components of shale, has an important influence on the enrichment of shale gas. However, there are currently only a few studies on this topic.
