Abstract

MÉTODO PARA DEDUZIR PARÂMETROS DE PROPRIEDADES FÍSICAS DE SUBSUPERFÍCIE PARA EXPLORAÇÃO SÍSMICA. Um método para modelar e migrar dados sísmicos, que inclui usar uma equação de onda acústica e uma distribuição espacial de um ou mais parâmetros de modelo terrestre. A equação de onda acústica é modificada incluindo pelo menos um termo de fonte secundária e, com base em uma configuração de aquisição sísmica, calculando os sinais sísmicos que seriam detectados a partir do campo de ondas modelado ou migrando sinais sísmicos observados ou migrando sinais residuais como parte de uma inversão.
