Abstract

The purpose of redatuming is to transform seismic data acquired at a certain measurement surface to simulated data as if acquired at a different measurement surface. Based on the chaining of diffraction-stack migration and isochron-stack demigration, we derive a 2.5D true-amplitude diffraction-stack-type redatuming operator and present its specific form for zero-offset data. The operator consists of performing a single weighted stack along adequately chosen stacking lines. For simple types of media, we derive analytic expressions for the stacking lines and weight functions and demonstrate its functionality with numerical examples.
