Abstract: A technique includes processing seismic data indicative of samples of at least one measured seismic signal in a processor-based machine to determine basis functions that represent a constructed seismic signal based at least in part on a matching pursuit-based technique. The technique further includes basing the determination of the basis functions at least in part on a predicted energy distribution of the constructed seismic signal.

Abstract: 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.

Abstract: A technique includes receiving sensor data; sorting the data into a gather representation that corresponds to a plurality of shots of an energy source; and determining a signal cone based at least in part on at least one characteristic of the gather representation. The technique includes processing the sensor data in a processor-based machine to attenuate noise to generate data representing a signal based at least in part on the determined signal cone and the gather representation.
