Abstract

"MéTODO PARA PROCESSAMENTO DE DADOS SìSMICOS DE SENSOR DUPLO PARA ATENUAR RUìDO". A presente invenção refere-se a um método é descrito para o processamento dos dados sísmicos provenientes de sensores de pressão e geofones colocados juntos simultaneamente gravados. Os dados sísmicos são processados primeiro determinando um campo de onda ascendente e um campo de onda descendente nos dados sísmicos. A subtração adaptável é então aplicada a pelo menos um entre o campo de onda ascendente e o campo de onda descendente para remover o ruído do sinal. Em modalidades alternativas, o campo de onda ascendente pode ser usado como um modelo de ruído para o campo de onda descendente ou o campo de onda descendente pode ser usado como um modelo de ruído para o campo de onda ascendente.
