<p>A seismic streamer system 311 for acquiring seismic data includes a plurality of first cable sections 312a, 312b each employing a first sensor configuration therein, and at least one second cable section 314a, 314b 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 318 may, e.g., include a conventional hydrophone distribution, and the second sensor configuration 319 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.</p> |
