Abstract: Common Reflection Surface (CRS) stack, a new stacking technique compared with conventional common midpoint (CMP) stack, is a zero-offset profile imaging method independent of macro-model. CRS stack depends on determination of three wave-field attributes, makes a summation using reflections along the stack surface, and increases the stacking numbers from Fresnel zone, in order to boost up signal energy and improve the stack imaging quality. The real seismic data processing indicates that this method can increase both the ratio of signal to noise in profile and the continuity of reflective events.

Key words: seismic profile, imaging, common reflection surface, bin, common midpoint stack
