Abstract

Un método, que incluye: obtener un modelo de velocidad generado por un proceso de inversión completa de campo de ondas acústico; generar, con una computadora, un modelo Q variable al aplicar pseudo migración Q en los datos sísmicos procesados de una región de la subsuperficie, en donde el modelo de velocidad se utiliza como una restricción guiada en la pseudo migración Q; y generar, con una computadora, un modelo de velocidad de la subsuperficie final que recupera atenuación de amplitud causada por anomalías de gas en la región de la superficie al realizar un proceso de inversión completa de campo de ondas visco-acústico, en donde el modelo Q variable se fija en el proceso de inversión completa de campo de ondas visco-acústico.
