Abstract

Se describen sistemas y métodos computacionales que combinan filtros de dominio de frecuencia-número de onda ("dominio f-k") globales con selección de evento basada en autoimagen localizada, para generar un campo de onda resultante con impresiones de filtro reducidas sobre bordes de recopilación, ruido reducido y tratamiento correcto de energía no distinguible; los métodos son ejecutados aplicando filtros a la serie completa de datos sísmicos recopilados en el dominio f-k, para obtener un campo de onda resultante de datos registrados de presión y/o velocidad de partícula; la salida del filtro es descompuesta iterativamente de acuerdo con valores de inclinación locales usando procesamiento de autoimagen basado en descomposición de valor singular ("SVD"); las mismas localizaciones de muestra son extraídas usando SVD de la entrada, además de generar entrada para una iteración subsiguiente con datos retirados ya procesados; los métodos de procesamiento de autoimagen permiten el tratamiento correcto de la energía aliada espacialmente en la filtración del dominio f-k.
