Abstract: A shot interval between activations of at least one frequency-controllable survey source is determined, where the shot interval is determined based on an expected frequency of an output of the at least one frequency-controllable survey source. The at least one frequency-controllable survey source is activated using the determined first shot interval.

Abstract: Described herein are implementations of various technologies for a method for seismic data processing. The method may receive seismic data for a region of interest. The seismic data may be acquired in a seismic survey. The method may receive a summation that is based on a particle motion velocity component of a seismic wavefield in the vertical direction and the pressure component of the seismic wavefield. The method may predict an upgoing pressure component of the seismic wavefield for the region of interest. The method may compare the predicted upgoing pressure component to the received seismic data that corresponds to the received summation. The method may update the predicted upgoing pressure component based on the comparison. The method may use the updated upgoing pressure component in hydrocarbon exploration or production for the region of interest.

Abstract: Computing systems, methods, and computer-readable media for improving data quality are disclosed. In some embodiments, a method of quality checking seismic interpolation data is provided, where the method includes obtaining first measured seismic data acquired by a first plurality of seismic sensors; obtaining second measured seismic data acquired by a second plurality of seismic sensors; interpolating, from the first measured seismic data, respective seismic data values at locations corresponding to respective sensors in the second plurality of seismic sensors; calculating a plurality of interpolation differences, where respective interpolation differences are calculated as numerical differences between respective interpolated seismic data values corresponding to respective sensor locations in the second plurality of sensors and respective measured seismic data values corresponding to respective sensors in the first plurality of sensors; and calculating an average interpolation difference using at least the plurality of interpolation differences.
