Abstract

In this paper offset continuation is defined as a procedure which transforms seismic data from one common offset to different offset (in contrast to more particular case - offset continuation to zero offset (Deregowski,Rocca,1981)). The effect of sparse or irregular spatial sampling on processed data is often of crucial importance in every day seismic data processing. Offset continuation transformation based on the Kirchhoff approach preserves both flat and dipping events and is computationally efficient. Using this transformation the detrimental effects of irregular spatial sampling on the CDP time sections can be overcome. The aim of this paper is to present a new approach to offset continuation operator derivation on the base of MZO (migration to zero offset) transformation (Popavici, 1995) and to compare one with similar operator based on DMO (dip moveout) transformation.
