Abstract
A method is described for seismic amplitude analysis that uses a set of artificial and individually separable reflectors consistent with dip fields in the subsurface volume of interest to define an AVA basis functions; the AVA basis functions are used in true-3D AVA modeling and true-3D AVA inversion. The inversion result and well logs representative of the subsurface volume of interest are used to train a model to create a rock property prediction model. The method may apply the rock property prediction model to a second seismic image to generate a rock property volume. The method is executed by a computer system.
