Abstract

Морские геофизические съемки с распределенными сейсмическими источниками. По меньшей мере, некоторые из примеров вариантов осуществления представляют собой способы, включающие в себя выполнение морской геофизической съемки посредством буксирования множества высокочастотных источников, разнесенных по ширине группы датчиков, при этом высокочастотные источники имеют первую плотность источников по отношению к ширине; буксирования множества среднечастотных источников, разнесенных по ширине группы датчиков, при этом среднечастотные источники имеют вторую плотность источников по отношению к ширине, причем вторая плотность источников ниже, чем первая плотность; буксирования низкочастотного источника по ширине; активации высокочастотных, среднечастотных и низкочастотных источников.
