Inversion methods for the separation of blended data

The recording and storage capacity of modern seismic acquisition systems is continuously growing, enabling denser sampling and the acquisition of better-quality data. One big hurdle is survey time, since the duration of a survey is directly proportional to the number of sources fired. The proposed way forward is to deploy nearly simultaneous...

Iterative separation of blended marine data: Discussion on the coherence-pass filter

n conventional marine acquisition surveys the time intervals between the firing of successive sources are large enough to avoid interference in time. To obtain an efficient survey, the spatial source sampling is therefore often (too) large. How- ever, much attention has been drawn recently to blended ac- quisition designs, where sources are shot...
