Abstract

In a blended acquisition, source encoding is needed for the separation of the blended source responses. The source ghost introduced by the strong sea surface reflection can be considered as a virtual source located at the mirror position of the actual source. In this abstract, we propose an acquisition concept that includes the source ghost as a natural source encoding such that it can be used for deblending, where the end result is deblended as well as deghosted. This acquisition method is easy to combine with man-made source encoding and also the concept of using the source ghost provides an interesting alternative to deal with the current depth distributed source for the broadband seismic data.
