Parameterization, stacking, and inversion of locally coherent events with the Common-Reflection-Surface Stack method

The Common-Reflection-Surface Stack method relies on the presence of locally coherent reflection events in the seismic prestack data. Using a secondorder traveltime approximation in an automated coherence analysis, such events are locally characterized by means of so-called kinematic wavefield attributes. The most important purpose of these attributes is velocity model building within as well as beyond the second-order assumptions inherent to the CRS approach.
