Abstract
"MéTODO DE LEVANTAMENTO SìSMICO DO SUBSOLO MARìTIMO". A presente invenção diz respeito a um método de levantamento sísmico do subsolo marítimo, a intervalos de tempo, utilizando uma fonte sísmica e um receptor sísmico (11, 12) numa posição pré-determinada, compreendendo o referido método as seguintes etapas: posicionar a fonte sísmica (13) na posição (15); registrar para essa posição (15) e para cada receptor sísmico (11, 12) um conjunto de pelo menos dois sinais de repetição em estados do mar diferentes, mas com um intervalo de tempo tão curto um em relação ao outro que podem se ignoradas as diferenças nos sinais de repetição devidas a alterações no subsolo marítimo, e medir os tempo do trajeto bidirecional na água quando se registra os sinais de repetição; posicionar, após um período de tempo pré-determinado, a fonte sísmica (13) na mesma posição (15), registrar para cada receptor sísmico (11, 12) um sinal de monitorização, e medir o tempo do trajeto bidirecional na água quando se registra o sinal de monitorização; assumir para o sinal um modelo que inclui o sinal de subsolo marítimo, as diferenças nos sinais de subsolo marítimo devidas a alterações no subsolo marítimo, e as contribuições dos reflexos múltiplos de superfície; determinar um conjunto de funções de filtro dos tempos medidos do trajeto bidirecional na água na posição (15) que permitem eliminar os reflexos múltiplos de superfície; calcular para cada receptor (11, 12) as diferenças estimadas entre os sinais de subsolo marítimo e os sinais de repetição, o sinal de monitorização e a(s) função/funções de filtro, sendo essa diferença estimada uma medida das alterações sinal de subsolo marítimo provocadas pelas alterações na camada-alvo no intervalo de tempo decorrido entre o registro dos sinais de repetição e o registro do sinal de monitorização; e emitir a diferença estimada.
