I have just gotten my first filtered seismic image using prediction error filters (PEFs), so I thought I should share this experience with our Acceleware blog readers. Coming from electromagnetic field modeling, I have quite a bit of experience with wave propagation through different types of materials. However, image filtering is a whole new (and interesting) world to me.

As most of the people doing seismic imaging know, reverse time migration (RTM) images obtained using a simple cross-correlation condition contain low frequency artifacts created by the unwanted cross-correlation of head waves and backscattered waves. These artifacts are clearly visible as the dark areas near the top of the BP model example shown in figure below.
