Abstract

Patente de Invenção: <B>"MéTODO E SISTEMA PARA AUMENTAR A RAZãO ENTRE O DESDOBRAMENTO REFLEXIVO E A EXTENSãO DE UM FILETE DE RECEPTORES"<D>. Trata-se de um método e sistema para utilização em levantamentos marítimos de dados sísmicos para acréscimo de desdobramento de reflexão ("fold") e de desvio sem acréscimo da extensão dos filetes de receptores ou das forças de arrasto na embarcação que reboca os filetes de receptores. Na generalidade o método compreende a utilização de uma segunda embarcação de fonte posicionada na via de percurso de filetes de receptores e o disparo da segunda fonte (S2) em um momento anterior ao término do registro das informações da primeira fonte (S1). Mediante o posicionamento da segunda fonte (S2) cerca de um comprimento de filete de receptores adiante do hidrofone mais próximo (R1), o desdobramento de reflexão é acrescido para o dobro para a mesma extensão de filete de receptores.
