МОРСКАЯ СЕЙСМИЧЕСКАЯ РАЗВЕДКА

摘要

A seismic data acquired using a seismic source array that emits a seismic wavefield having a frequency spectrum within the seismic bandwidth that does not contain a source ghost at a non-zero frequency is processed to attenuate the effect of ghost reflections in the seismic data. Independent claims are also included for: (a) a seismic surveying arrangement comprising a seismic source array that emits a seismic wavefield having a frequency spectrum that does not contain a notch at a non-zero frequency, seismic receiver(s) for acquiring seismic data, and an apparatus for processing seismic data acquired at the receiver(s); (b) a storage medium containing a program for controlling a data processor.
