Abstract

With the increased industry interest in low frequencies, there has been a significant effort in developing techniques that can source these low frequencies. The importance of recording the full range of frequencies (low as well as high) is widely accepted for high resolution imaging. High fidelity, low frequency data provides deeper penetration for the clear imaging of deep targets, as well as providing greater stability in inversion. During Previous HitprocessingNext Hit of broadband data, it is crucial to make sure that the Previous HitsignalNext Hit contained in each of the octaves composing the total seismic response is preserved. In this paper we will discuss how the broadband Previous HitsignalNext Hit can be effectively controlled at each stage of the Previous HitprocessingNext Hit sequence through a wavelet splitting technique, opening the way for the recovery of the full broadband Previous HitsignalTop in the image domain. This method can be applied on any seismic data set, whatever its octave content, pre-stack or post-stack.
