Abstract

Se describen métodos y sistemas de cómputo para eliminar el fantasma de los datos de cable marino sísmico marino; en particular, una embarcación de exploración sismológica arrastra una cantidad de cables marinos que forman una superficie de adquisición de datos localizada debajo de una superficie libre; los métodos eliminan el fantasma computacionalmente o remueven sustancialmente señales fantasma de los dados sísmicos grabados por receptores del cable marino; los métodos de eliminación de fantasma incluyen compensación de baja frecuencia para recuperar información del campo de onda de velocidad vertical que se pierde normalmente debido a una baja proporción de señal a ruido sobre un rango de baja frecuencia independiente de las condiciones de superficie libre o de la forma de la superficie de adquisición de datos.
