Title:
TWO COMPONENT SOURCE SEISMIC ACQUISITION AND SOURCE DE-GHOSTING
Document Type and Number:
WIPO Patent Application WO/2012/154294
Kind Code:
A4
Abstract:
Method for marine seismic acquisition using both monopole (91) and dipole (92) source types. Through a combination of source design and operation and/or combination or summing of the data in a processing step, the source ghost is either attenuated or, if desired, enhanced (93). The properties of the two different source types allow them to be adjusted so that the first down going wave from each has either opposite polarity or the same polarity, whereas the source-ghost wave will have, respectively same polarity or opposite polarity. This allows cancellation or enhancement of the source ghost. If the survey also employs two- component sensor acquisition, then the combined data sets may be both sensor de-ghosted and source de-ghosted.
