Abstract
In the past years, numerous efforts have been made to increase the bandwidth of seismic data, both for the low and the high frequencies. Seismic data has gained two octaves in the low frequencies (from 10 Hz down to 2.5 Hz) and more than one octave in the high frequencies (from 80 Hz to 160 Hz and up to 200 Hz). This has the potential to fill the information gap described by Claerbout (1985). The aim of this paper is to discuss this gap and present two real data examples of variable-depth streamer acquisition where this goal has been achieved.
