Comparison of Generalized Multilayer Stolt Migration with Reverse-Time Migration

The generalized multilayer Stolt migration (GMSM) algorithm is compared with the reverse-time migration (RTM) regarding computational complexity and focused image quality. The GMSM is a recently developed algorithm that can image subsurface objects buried in an obliquely layered geometry based on the frequency-wavenumber domain migration. The newly developed algorithm produces images of subsurface geometry in a short time. Actual computation times and qualities are compared to the RTM for an obliquely layered geometry. The GMSM was shown to be efficient algorithm in terms of the computation time. The quality of the images produced by the two algorithms are shown to be essentially the same.
