Abstract

"MéTODO DE MIGRAçãO DE PRé-EMPILHAMENTO EM TEMPO DE KIRCHHOFF PARA ONDAS PS". A presente invenção refere-se a um método é mostrado para a migração de dados sísmicos, o qual inclui a determinação do tempo de percurso de uma onda compressional de um local de fonte até um ponto de dispersão, levando-se em consideração uma curvatura de raio. O tempo de percurso de onda cisalhante do ponto de dispersão até um local de recepção é determinado, levando-se em consideração a curvatura de raio nas interfaces entre estratos de subsuperfície. Os tempos de percurso determinados então são usados para a migração dos dados sísmicos. Em uma modalidade, os tempos de percurso levam em consideração meios isotrópicos transversalmente de modo vertical com um eixo de simetria vertical.
