Marine Data Processing Results Reliability Increasing

In conventional marine seismic surveys, the air-guns and streamer(s) are placed at certain predefined depths below the sea surface. The decision of source/receiver depths for any given survey is based on several conditions, including weather conditions, desired frequencies, equipment type etc. In addition to those, the location of the notch in the frequency spectrum created by the surface ghost reflections is something that must be considered. Ghosting is a direct result of placing the source and receivers near a sharp discontinuity, which is the water/air contact in marine acquisition. The result of deghosting procedure are images quality environment, increases the reliability of geological tasks. There is no need to focus on the positive effects of this procedure during the expansion of the spectrum to higher frequencies. In recent times, a growing interest is the low frequencies that increase the stability of seismic inversion and tying processing results to well data.
