Abstract

METHODS AND SYSTEMS FOR QUANTIFYING COHERENCY AND CONSTRAINING COHERENCY-BASED SEPARATION IN SIMULTANEOUS SHOOTING ACQUISITION This disclosure presents methods and systems for deb lending blended seismic data obtained during simultaneous shooting acquisition into deblended seismic data gathers. Methods and systems iteratively separate the blended seismic data into the deblended seismic 10 data gathers based on semblance analysis of a residual difference between the blended seismic data and the deblended seismic data gathers. Each deblended seismic data gather is associated with one of the sources and appears to have been obtained without substantial interference from seismic energy produced by other sources. 15 FIG. 11 31
