Abstract

We have applied Common Reflection Surface (CRS) stack to two different seismic data sets i.e. multifold seismic data of Mahanadi Basin to image the sedimentary environment and multi coverage deep seismic reflection data of Nagauar Jhalawar Geotransect in Delhi Aravalli Fold Belt to image the crust and sub crust region. Same data have been also processed using conventional data processing chain (CMP processing). In comparison with CMP stack, it has been observed that image has been greatly enhanced in CRS stack. Moreover as it makes use of seismic data from CMP direction as well as off CMP direction, better continuity of the reflectors and enhanced signal to noise(S/N) are achieved. These results show that CRS stack provides better image not only in sedimentary environment but also for the crust and sub crust region.
