The main assumptions are that the wavelet is an exponential form that allows for analytic integration over frequency, and the direction of propagation and arrival time are as dictated by ray theory. These assumptions result in calculations sufficiently rapid to be carried out interactively on the computer. Results for an AVO Class I model show that this method quantitatively reproduces exact spherical‐wave reflection coefficients obtained using a Ricker wavelet.Permalink: https://doi.org/10.1190/1.2144299FiguresReferencesRelatedDetailsCited BySingle-Sided Ultrasound Imaging of the Bone Cortex: Anatomy, Tissue Characterization and Blood Flow25 November 2021Influence of upscaling on identification of reservoir fluid properties using seismic-scale elastic constants10 September 2019 | Scientific Reports, Vol. 9, No. 1Target-oriented linear least squares and nonlinear, trust-region Newton inversions of plane waves using AVA and PVA data for elastic model parametersTing Gong and George A.
