Abstract

Un método para modelar y migrar datos sísmicos, que incluye usar una ecuación de onda acústica y una distribución espacial de uno o más parámetros de modelo de la tierra; la ecuación de onda acústica es modificada incluyendo al menos un término de fuente secundaria y basado en una configuración de adquisición sísmica, ya sea calculando las señales sísmicas que podrían ser detectadas a partir del campo de onda modificado o migrando las señales sísmicas observadas o migrando señales residuales como parte de una inversión.
