Abstract

1/1 resumo “emissão de baixa frequência e registro para aquisição de dados sísmicos” são apresentados métodos e sistemas para coleta de dados sísmicos marítimos. os dados sísmicos coletados podem ser de baixa frequência (por exemplo, menores que 10hz) ou podem ser uma largura de banda sísmica total (1-200 hz) dependendo se as fontes sintonizadas de baixa frequência e receptores sintonizados são combinados com receptores e fontes convencionais. as fontes de baixa frequência podem ser rebocadas ou podem ser autônomas e posicionadas na área de levantamento por atar, derivação ou de autopropulsão. os receptores de baixa frequência sintonizados são rebocados em uma profundidade maior que receptores convencionais e as fontes podem ser disparadas independentemente ou simultaneamente.
