This P/Z summation was very efficient for attenuating the ghost and water layer peg-leg multiples. The vast majority of marine seismic data are acquired with conventional towed streamer cables which are equipped only with hydrophones and are all towed essentially at the same constant depth for any single survey. Learn how early understanding of subsurface challenges can save time and costs. Most initial seismic processing attempts to remove noise so the data can be migrated with optimum quality after the velocity model is derived.
