Abstract

Se describe un método generador de imágenes del subsuelo comenzando por la obtención de señales iniciales a partir de un levantamiento geofísico que ha sido obtenido con múltiples fuentes de energía geofísica accionadas en una pluralidad de secuencias de disparos, cada secuencia con un tiempo conocido de retraso entre los tiempos de disparo de cada fuente; las señales iniciales están agrupadas en agrupación de señales adquiridas a partir de múltiples secuencias de disparo; para cada agrupación, estimados iniciales de campos ondulatorios de la primera y segunda fuente son determinados; señales sensibles para la primera fuente son entonces generadas para representar las señales iniciales menos una corriente estimada del campo ondulatorio de la segunda fuente; una operación de separación coherente de energía es aplicada a las señales sensibles para obtener un estimado perfeccionado para el campo ondulatorio de la primera fuente.
