What is all the buzz about?

摘要

BE is a novel technique for extending the usable bandwidth of seismic data. I don't have enough bandwidth in my seismic! We had to filter out the low frequencies during acquisition to attenuate the ground roll, and the high frequencies were absorbed during transmission down to my target and back up to the surface. So I am left with data that has only about 15-50 Hz of usable frequency. That might be okay if I were looking for thick sands, but I'm not - my targets are thin, which means I need frequencies up in the 90 or 100 Hz range to have any chance of really seeing them."
