Abstract
Methods and apparatus for noise removal from seismic data. In one embodiment, a seismic data set comprising a plurality of traces is received, and noise metrics for the seismic data set are computed using a set of time and depth windows. The seismic data set is scanned to determine a first set of groups. Each group in the first set comprises at least a first minimum number of neighboring traces for which at least one of the noise metrics is outside a predefined specification. Noise attenuation is applied to the traces in the first set of groups. Other embodiments, aspects, and features are also disclosed.
