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.
