In this paper a new technique in seismic imaging is studied. According to the limitations in conventional marine seismic surveys such as imaging of complicated geology in deep water, a quest for new and alternative technologies such as OBNs (ocean-bottom nodes) motivated.

“High-quality data from the sea floor can be acquired with ocean-bottom node acquisition techniques which can provide wide-azimuth data set with sparse receiver interval and dense source interval. OBS systems inherently have the potential for broad bandwidth and lower frequencies than towed streamer systems. “
