摘要： A technique includes decomposing a signal that is derived from a seismic acquisition into a plurality of signals such that each signal is associated with a different frequency band. For each signal of the plurality of signals, the technique includes performing the following: decomposing the signal into subbands in successive stages, where the subbands are associated with at least different frequency ranges of the signal; selectively applying adaptive noise attenuation in between the successive stages such that the stages decompose noise-attenuated subbands; and reconstructing the signal from the subbands resulting from the decomposition. The technique includes combining the reconstructed signals.

摘要： A technique includes spatially filtering a signal that is derived from a seismic acquisition. The filtering is associated with a filter length, and the filtering includes varying the filter length with frequency. The filtering may be used in connection with adaptive noise attenuation, which is applied to decomposed subbands. Furthermore, the filtering may be applied during the reconstruction of the signal from the subbands.

摘要： A method for processing seismic data. The method may include (1) receiving seismic data acquired by an ith seismic sensor of a plurality of seismic sensors and (2) determining an ith value to represent an ith power spectral density curve that corresponds to the seismic data. The method may then repeat steps (1)-(2) for each seismic sensor. The method may then include generating an expected value curve based on the ith value for each power spectral density curve. The method may then compare each ith value to the expected value curve and identify invalid seismic sensors based on the comparison. After identifying the invalid seismic sensors, the method may process the seismic data without seismic data acquired by the invalid seismic sensors to determine one or more locations of hydrocarbon deposits in subterranean geological formations.
