Title:
METHOD AND DEVICE FOR DE-BLENDING SEISMIC DATA USING SOURCE SIGNATURE
Document Type and Number:
WIPO Patent Application WO/2015/001058
Kind Code:
A3
Abstract:
Methods and devices for seismic data processing de-blend seismic data using the different source signatures as discriminating factors. The methods may be used when sources were fired with dithering times.
