Nettet26. mar. 2012 · Compared to linearized inversion, this method is computationally intensive; therefore, Buland and Omre ( 2003) developed a new linearized AVO inversion technique to estimate posterior distributions for P-wave and S-wave velocity, and density. Nettet24. apr. 2024 · Simultaneous prestack inversion is based on the modified Fatti equation and uses the ratio of the P- and S-wave velocity as constraints. We use the relation of P-wave impedance and density (PID) and S-wave impedance and density (SID) to replace the constant Vp/Vs constraint, and we propose the improved constrained Fatti equation …

NettetAnd then, Russell et al proposed the linearized AVO approximate equation characterized by the Gassmann fluid term f. Han and Batzle ( 2004 ) discussed the simplification of the Gassmann equation considering fluid-saturation effects and gave the linearized expressions between f and the fluid modulus K f for sand reservoirs with high porosities.
