Thin-bed prestack spectral inversion
Web17 Sep 2012 · where the acoustic impedance I t = v t × ρ t, v t is the velocity and ρ t is the density at a two-way time t.The inversion for the reflection coefficients is a linear problem, but for acoustic impedance is nonlinear. The stochastic methods can directly use the nonlinear equivalence equation for the forward modelling; but deterministic methods have … WebRubino, J.G.; Velis, D., 2009: Thin-bed prestack spectral inversion

WebDip-steered mean filters work well on prestack data in which discontinuities appear as smooth diffractions, but smear faults and stratigraphic edges on migrated data. Dip-steered median and alpha-trimmed mean filters work somewhat better but will still smear faults. Hoecker and Fehmers (2002) address this problem WebIn summary, thin-bed tuning affects poststack and prestack seismic amplitudes. Simple synthetic-modeling tools such as those presented in this tutorial allow you to gauge the …
