Abstract

There are numerous laboratory and field examples in which low-frequency components of reflected seismic waves show surprising imaging capabilities. Ironically, such components are often filtered out as useless in conventional data processing. However, as we demonstrate below, this part of the signal contains the most important information about the reservoir.
