title = "3D common-shot depth imaging with an optimized Fourier finite-difference scheme",
abstract = "We extend the globally optimized Fourier finite-difference migration method to three dimensions and investigate its capability for imaging complex 3D subsalt structures. The method operates on common-shot data in the frequency domain and uses a combination of the split-step Fourier propagator implemented in the wavenumber and space domains and a second-order finite-difference propagator applied in the space domain. The coefficients in the finite-difference propagator are optimized for the entire extrapolation depth interval. It can accurately and efficiently handle large lateral velocity variations and steep interfaces. We conduct impulse response studies, and using the method to migrate a common-shot dataset for the SEG/EAGE 3D salt model and a common-shot deepwater Gulf of Mexico dataset from Unocal. The results demonstrate that the method has great potential to accurately image complex 3D subsalt structures.",
