NOISE MITIGATION IN SEISMIC MULTIMEASUREMENT DATA

摘要

Computing systems, methods, and computer-readable media for noise mitigation in seismic multimeasurement data are disclosed. In some embodiments, a computer-implemented method for noise mitigation of seismic wavefield data measured by a seismic streamer is provided, where the method utilizes correlation between multiple components of the seismic wavefield data, and where the method includes adjusting a magnitude of measured inline particle motion of the seismic wavefield to not exceed a computed upper bound power spectral density of an inline component of the seismic wavefield, adjusting a magnitude of measured crossline particle motion of the seismic wavefield to not exceed a computed upper bound power spectral density of a crossline component of the seismic wavefield, adjusting a magnitude of measured vertical particle motion of the seismic wavefield to not exceed a computed upper bound power spectral density of a vertical component of the seismic wavefield, and outputting data representing the seismic wavefield.
