HUBRAL Geophysical Institute University of Karlsruhe Hertzstr. 16 76187 Karlsruhe Germany Summary. The Common-Reflection-Surface (CRS) stack was originally introduced as a data-driven method to simulate zero-offset sections from 2-D seismic reflection pre-stack data acquired along a straight line. This approach is based on a second-order traveltime approximation parameterized with three kinematic wavefield attributes. An explicit knowledge of the subsurface model is not required but only the nearsurface velocity. Meanwhile the attractive features of the CRS approach have been transferred to more general imaging problems: the simulation
