Abstract

Se describen técnicas relacionadas con la configuración de un estudio sísmico marino; en algunas modalidades, un buque (210) puede estar acoplado a una o más fuentes sísmicas (220) y uno o más los cables marinos sísmicos (250), y un segundo buque (230) puede estar acoplado a una o más fuentes sísmicas de desplazamiento lejano (240); las fuentes de desplazamiento cercano (220) pueden configurarse para actuar de acuerdo con un intervalo de punto de disparo; las fuentes de desplazamiento lejano (240) pueden configurarse para actuar de acuerdo con un intervalo de punto de disparo más largo; en algunas modalidades, el intervalo de punto de disparo más largo puede ser un múltiplo del intervalo de punto de disparo de la fuente de desplazamiento cercano; la determinación del primer y segundo intervalos de punto de disparo se puede basar en parte, por ejemplo, en las frecuencias de onda de las fuentes de desplazamiento lejano, los requisitos de un procedimiento de inversión de onda completa o varios parámetros de configuración de estudios sísmicos.
