Abstract
Reverse time migration (RTM) is theoretically more accurate than traditional migration methods because it computes numerical solutions to the complete wave equation. But RTM is computationally expensive especially for 3D data. To overcome this expense, Luo amd Schuster (2004) suggested a bottom-up reverse time datuming (RTD) method that promised to significantly decrease the computational time for obtaining RTM images. Here we implement this idea for imaging of 3D synthetic data. The preliminary results indicate that the target-oriented RTD can reveal deep structures below the datum with less calculation effort than the full volume RTM.
