Improved AVO fluid detection and lithology discrimination using Lamé petrophysical parameters: "λp", "µp", and "λ/µ fluid stack": from P and S inversions

B. Goodway, T. Chen and J. Downton

…Introduction Traditional AVO and petrophysical analysis extract and exploit anomalous variations between seismic compressional wave velocity (Vp) and shear wave velocity (Vs) to indicate changes primarily in pore fluid, as well as lithologic properties (Gassmann 1951, Pickett 1963, Tatham 1982, Castagna 1993a). Other analysis methods using seismic measurements derive Poisson's…
