Full-waveform inversion with multisource frequency selection of marine streamer data

Abstract

The theory and practice of multisource full-waveform inversion of marine supergathers are described with a frequency-selection strategy. The key enabling property of frequency selection is that it eliminates the crosstalk among sources, thus overcoming the aperture mismatch of marine multisource inversion. Tests on multisource full-waveform inversion of synthetic marine data and also the Gulf of Mexico data show speedups of 4 × and 8 ×, respectively, compared with conventional full-waveform inversion.
