Widely exploited in the industry, amplitude-variation-with offset (AVO) inversion techniques are based on weak-contrast approximations of the plane-wave reflection coefficients. We suggest an approach to long-offset AVO inversion for curved interfaces within a seismic frequency range using the modified version of effective reflection coefficients (ERCs). The effective reflection coefficients generalize the plane-wave and spherical-wave reflection coefficients for waves generated by point sources and reflected at curved interfaces. They account for the wavefront curvature and are adequate at any incidence angle
