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 ...
