Marine seismic data contains a receiver ghost and a separate source ghost. Full ghost-free imaging for the widest possible signal bandwidth applies technology that removes both these unwanted reflections. PGS GeoSource® is a time and depth distributed source that uses sub-sources at varied depths and fired with specific time delays. The ghost functions of the sub-sources are complementary and when combined restore the full signal bandwidth.
