Abstract

o método processa entrada (ds,g[t]) incluindo, para cada um de uma pluralidade de pulsos nas respectivas localizações de fonte, traços sísmicos registrados em uma pluralidade de localizações de receptores. dados modulados de ponto médio comum (d's,g[t]) são também computados ao multiplicar os dados sísmicos em cada traço sísmico através de um ponto médio horizontal. um processo de migração de profundidade é aplicado (i) aos dados sísmicos para obter um primeiro conjunto de dados migrados (ms[x,y,z]), e (ii) para dados modulados de ponto médio para obter um segundo conjunto de dados migrados (m's[x,y,z]). para cada pulso, valores de abertura (âs[x,y,z]) são estimados e associados com posições de subsuperfície respectivas, através de um processo de divisão aplicado ao primeiro e ao segundo conjuntos de dados migrados. um valor migrado (rx,y[z,a]) para uma profundidade "z" e uma abertura "a" em uma coleta de imagens comuns de abertura de superfície (cig) em uma posição horizontal x, y é um valor migrado do primeiro conjunto de dados migrados associados com uma posição de subsuperfície x, y, z para um pulso tal que o valor de abertura estimado associado com tal posição de subsuperfície é a abertura "a".
