Abstract
Summary
Three focusing imaging approaches are presented which are based on Kirchhoff prestack depth migration. All approaches can be formulated as a weighted diffraction stack with different weighting functions. In any case the smearing along the two-wave-traveltime isochrone is limited to the physically relevant part at the specular reflection or diffraction point. The focusing characteristics of these approaches can be very valuable for increasing the image quality, both for hydrocarbon exploration data sets as well as for imaging in complex crystalline crust.
