Abstract
La técnica de adquisición sísmica divulgado en la presente emplea una matriz de receptores y una metodología de procesamiento que están diseñados para atenuar el ruido de fondo sísmico que ocurre naturalmente junto con los datos sísmicos durante la adquisición. El enfoque apalanca el conocimiento de que el ruido de fondo sísmico que ocurre naturalmente se mueve con una velocidad de fase más lenta que las señales sísmicas usadas para la formación de imágenes y la inversión y, en algunas realizaciones, puede llegar desde direcciones preferidas particulares. La técnica divulgada comprende dos pasos: 1) determinar a partir del ruido de fondo sísmico que ocurre naturalmente en los datos sísmicos preliminares, un rango de velocidades de fase y amplitudes que contienen principalmente ruido y el nivel al cual el ruido necesita ser atenuado y 2) diseñar un método de adquisición y procesamiento para atenuar ese ruido en relación con la señal deseada.
