Abstract

AGRUPAMENTOS DE DESLOCAMENTO DE MIGRAÇÃO DE EQUAÇÃO DE ONDA. Um método inclui receber, por meio de um processador, dados de entrada com base em dados sísmicos recebidos, migrar, por meio do processador, os dados de entrada por meio de uma técnica de migração de profundidade de préempilhamento para gerar dados de entrada migrados, codificar, por meio do processador, os dados de entrada por meio de uma função de codificação como um atributo de migração para gerar dados de entrada codificados tendo uma função de migração que é não monotônica versus um atributo relacionado aos dados de entrada, migrar, por meio do processador, os dados de entrada codificados por meio da técnica de migração de profundidade de pré-empilhamento para gerar dados de entrada codificados migrados, e gerar um agrupamento de imagem comum estimado com base nos dados de entrada migrados e nos dados de entrada codificados migrados. O método também inclui gerar uma imagem sísmica utilizando o agrupamento de imagem comum estimado, em que a imagem sísmica representa hidrocarbonetos em uma região de subsolo da Terra ou perigos de perfuração de subsolo.
