Abstract

Los datos sísmicos son adquiridos activando una primera fuente en un primer momento y una o más fuentes sísmicas adicionales, cada una con sus propios tiempos características con respecto a un momento de registro de señal, las fuentes substancialmente colocadas y en profundidades diferentes; se determinó un primer campo de onda que podría ocurrir si la primera fuente fuera activada en un momento seleccionado con respecto a un momento de inicio de los registros y siendo ajustado por tiempo a la profundidad del agua; se determinaron uno o más campos de onda adicionales que podrían ocurrir si una o más fuentes adicionales fuera cada una activada en dicho momento seleccionado con respecto a dicho tiempo de inicio, y siendo ajustado por tiempo para las profundidades del agua de la una o más fuentes adicionales; el primer campo de onda y el uno o más campos de onda adicionales se combinan para determinar un campo de onda fuente sin imágenes borrosas que corresponde a la activación de una fuente de energía sísmica única.
