Wave velocity in shale in the Wufeng-Longmaxi formation in Sichuan Basin

Journal of Geophysics and Engineering, 2022
Abstract Analyzing the pattern of wave velocity is important for velocity prediction and amplitude-versus-offset analysis during unconventional seismic exploration. Several parameters, including the maturity and microstructure of organic matter (OM), the wave velocity, the mineral composition and the density of shale from Upper ...

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.

Water Distribution in the Ultra-Deep Shale of the Wufeng–Longmaxi Formations from the Sichuan Basin

Energies, 2022
Recently, deep and ultra-deep shales (depth >3500 m) of the Lower Paleozoic Wufeng–Longmaxi formations (WF–LMX) have become attractive targets for shale gas exploration and development in China, and their gas contents may be influenced by the occurrence of water to some extent.
