Description

During the acquisition of a source-over-cable survey in the Barents Sea, part of one sail line was repeated without triggering the airgun arrays. The acoustic wavefield generated by the source vessel sailing over the streamers has been characterized from the measured direct arrivals. The image obtained after deconvolving this wavefield from the received wavefield will be presented and compared to the image obtained from an airgun source.


Participants' Profile

Geophysicists interested in acquisition as well as imaging.
