Summary:
P168 WAVEFIELD EXTRAPOLATION BASED ON THE LOCAL SLANT STACKING MICHAEL DENISOV and DMITRI FINIKOV 1 Geotechsystems Ordzhonikidze 13/2 117071 Moscow Russia Introduction A procedure for transforming data from the original source/receiver depth level to a different one is usually called wavefield extrapolation. The most important applications of this technique are simulation of multiples and peg-legs for their subsequent subtraction and pre- or post-stack datuming. A typical approach to the design of the wavefield extrapolator is the use of the wave equation that results in a Kirchhoff summation operator that maps the surface data into a multiple model or in other
