Abstract: A technique includes generating vibroseis sweeps for a vibroseis survey to produce seismic data acquired in response to seismic signals produced by the sweeps. The generation of the vibroseis sweeps including temporally arranging the sweeps into time-overlapping groups. The technique includes regulating a timing of the groups relative to each other based on a slip time. The technique also includes regulating a timing of the sweeps of each group such that consecutive sweep firings of each group are spaced apart by a time substantially less than the slip time.

Abstract: A seismic streamer system for acquiring seismic data includes a plurality of first cable sections each employing a first sensor configuration therein, and at least one second cable section operatively connected to one or more of the first cable sections and employing a second sensor configuration therein. In various embodiments of the streamer system, one or more of the second cable sections are sparsely integrated into a streamer, a streamer array and/or a seismic spread. The first sensor configuration may, e.g., include a conventional hydrophone distribution, and the second sensor configuration may, e.g., include multicomponent sensors such as at least one of a particle velocity sensor, a pressure gradient sensor, an accelerometer and a combination thereof. The present invention is useful for attenuating noise in the measured seismic data as well as deghosting the data. A particular deghosting process includes decomposing the up- and down-going parts of the vertical component of particle velocity associated with the acoustic wave reflections from the strata.

Abstract: Methods and computing systems for processing collected data are disclosed. In one embodiment, a method is provided for predicting a plurality of surface multiples for a plurality of target traces in a record of multi-component seismic data acquired in a survey area. The method may select a target trace. The method may select an aperture of potential downward reflection points for the target trace. The method may calculate dip propagation attributes from the multi-component seismic data. The method may map the dip propagation attributes into a multiple contribution attribute gather based on the aperture. The method may modify the aperture based on the multiple contribution attribute gather. The method may then predict multiples for the selected target trace using the modified aperture.
