Abstract

Patente de Invenção:<B>"MéTODO DE REDUçãO DE RUìDO DE TRAçOS DE DADOS SìSMICOS"<D>. Um método de supressão de ruído coerente de rajada em dados sísmicos é provido, compreendendo: a) a comparação de um valor de aceitação de característica de amplitude limite para uma janela de tempo de um traço de referência com uma característica de amplitude de um traço de teste de um conjunto de traços na janela, e b) a aplicação de um escalar não-nulo ao traço de teste na janela de tempo se a amplitude do traço de teste na janela de tempo não estiver no valor de aceitação de característica de amplitude limite.
