Abstract

"ANáLISE DE VELOCIDADE DE MIGRAçãO DE PROFUNDIDADE RESIDUAL BASEADA EM HORIZONTE". A presente invenção refere-se a um método para processamento de dados sísmicos. O método inclui a migração de profundidade pré-pilha dos dados sísmicos para a geração de acumulações de imagem comum usando-se um modelo de velocidade - profundidade inicial. Os horizontes nos dados sísmicos migrados são selecionados. Análise de velocidade de migração residual no domínio de profundidade - desvio é realizada com relação a cada horizonte selecionado, e o modelo de velocidade - profundidade é atualizado com base na análise de velocidade de migração residual.
