Abstract

Accurate imaging of the deeper sub-surface remains a challenge when the subsurface is complex. Conventional processing based on NMO, DMO and post stack migration is inadequate to bring out the subsurface images. Pre -stack migration on the other hand, involves velocity analysis and stack in the common image point (CIP or CRP) domain and thereby accounting the dips and diffraction energies. The present study deals with the 3D pre stack time imaging using Kirchoff
