Industry Article: Exorcising the Ghosts - Over/Under Technology

An over/under, towed-streamer configuration is a method of acquiring seismic data where cables are towed in pairs at two different depths, with one cable positioned above the other. The depths of these paired cables typically are significantly deeper than for a conventional towed streamer. It is possible to acquire data with paired sources at two differing depths in conjunction with the paired cables. The paired sources are also deeper than those used in a conventional towed-streamer configuration.
