Abstract

Un método, que incluye: obtener un modelo geofísico inicial; modelar un campo de ondas hacia adelante con ecuaciones de onda viscoacústica o viscoelástica; modelar un campo de ondas adjunto con las ecuaciones de onda viscoacústica adjunta o viscoelástica adjunta, en la donde las ecuaciones de onda viscoacústica adjuntas se basan en una variable auxiliar que es una función de tanto la presión como una variable de memoria o las ecuaciones de onda viscoelástica adjuntas se basan en una combinación de esfuerzo y una variable de memoria, respectivamente; obtener un gradiente de una función de costo en base a una combinación de un modelo del campo de ondas hacia adelante y un modelo del campo de ondas adjunto; y utilizar el gradiente de la función de costo para actualizar el modelo geofísico inicial y obtener un modelo geofísico actualizado.
