Abstract

Abstract: A brand new kind of approach is presented for seismic migration processing-Common Focus Point (CFP) imaging techniques in this paper. CFP imaging techniques will separate prestack migration from velocity analysis recurring to two consecutive and independent focusing steps, and substitute operator up-
dating for the direct updating of velocity filed in a traditional way, in the end calculate subsurface velocity filed using correctly updated focusing operator. The effectiveness of CFP imaging techniques was verified on a model.

Key words: common focus point, focusing operator, imaging, bifocal migration
