Abstract
B007 Do We Reduce Noise by Towing Deeper? E. Muyzert* (Schlumberger Cambridge Research) SUMMARY Common seismic industry wisdom is that a streamer towed close to the surface is noisier than a deeper streamer. Deep tow techniques such as over/under marine seismic acquisition therefore deliver quiet seismic data. An analysis of over/under marine seismic noise records acquired in moderate good weather showed that the reality is more complicated. It was found that the RMS energy of the full bandwidth of a noise record did not decrease with tow depth contradicting conventional wisdom. It was shown the noise records at frequencies above
