AVO modelling of linearized Zoeppritz approximations

Ali Fathalian and Kris Innanen

ABSTRACT

The reflection coefficients are investigated for the various approximation on Zoeppritz equation and the results compared with the exact solution. There some deviations near critical angles that for larger layer contrasts and larger angle of incidence these deviation are significant. Also, the effect of γ parameter on forward modelling is investigated. When the contrasts between the layers of model is larger, the γ parameter has more influence on forward modelling.
