Abstract
Abstract
Broadband towed-streamer data has extended the usable seismic bandwidth at both ends of the frequency spectrum. As well as enriching the overall seismic image, improved low frequencies have delivered more reliable full-waveform inversion results and more quantitative elastic inversion, while improved high frequencies enable better interpretation of thin-layered structures. Various strategies have been developed to acquire broadband data, ranging from processing-only approaches using horizontal-tow hydrophone-only streamers, to combined acquisition and processing schemes using multi-level streamers (Posthumus, 1993), variable-depth streamers (Soubaras, 2010) or multi-sensor streamers (Carlson et al., 2007).
