Linearized AVO Inversion with Modified Aki-Richards’ Approximation

NettetThe Aki-Richards’ linearized approximation of the Zoeppritz equations is one of the most commonly used approximation for AVO forward modeling and inversion. However, the linearized approximation is often not accurate enough for large incidence angles and strong impedance contrasts. NettetLinearized AVO and poroelasticity.
