In the last few years new imaging methods have been introduced. One of the most important and powerful procedure for seismic time imaging is Common Reflection Surface stack (CRS stack) method. In contrast to the conventional methods like NMO/DMO stack and pre-stack time migration which are based on velocity information, the CRS stack method is independent of a velocity model. In this study we perform a stacked section without any velocity analysis using CRS move out formula. In contrast to the conventional stacking process, signal-to-noise ratio and continuity of signal along the events are improved significantly using CRS stack method. In this study we use this method for 2D land data by inhomogeneous layers.
