Short Note Speeding up wave equation migration
نویسنده
چکیده
In this paper I discuss three different methods to speed up midpoint-offset domain downward continuation based migration. I compare the migration results with the more standard downward continuation method. I show that a factor of two speed up is achievable with little discernible loss in image quality. In addition I show that for velocity analysis purposes a factor of three to four speed up is achievable.

FDTD Based Seismic Modeling and Reverse Time Migration on a GPU Cluster
We have designed a fast parallel simulator that solves the acoustic wave equation on a GPU cluster. Solving the acoustic wave equation in an oil exploration industrial context aims at speeding up seismic modeling and Reverse Time Migration. We use a finite difference approach on a regular mesh, in both 2D and 3D cases. The acoustic wave equation is solved in either a constant density or a varia...
متن کاملShort Note Comparing Kirchhoff with wave equation migration in a hydrate region
Prestack migration is necessary before AVO analysis. Most of the present migration algorithms not only try to focus the reflections on the subsurface but also strive to preserve the amplitude for subsequent amplitude studies. A migration/inversion method developed by Lumley (1993) estimates the angle dependent reflectivity at each subsurface point by using least-squares Kirchhoff migration foll...
متن کاملShort Note Common-azimuth migration and Kirchhoff migration for 3-D prestack imaging: A comparison on North Sea data
Common-azimuth migration (CAM) is a 3-D prestack depth migration technique based on the wave equation (Biondi and Palacharla, 1996). It exploits the intrinsic narrow-azimuth nature of marine data to reduce its dimensionality and thus manages to cut the computational cost of 3-D imaging significantly enough to compete with Kirchhoff methods. Based on a recursive extrapolation of the recorded wav...
متن کاملWave Equations in Transversely Isotropic Media in Terms of Potential Functions (RESEARCH NOTE)
A complete series of potential functions for solving the wave equations in an almost transversely isotropic media is presented. The potential functions are reduced to only one potential function particularly for axisymmetric wave propagation problems. The potential functions presented in this paper can be reduced to Lekhnitskii-Hu-Nowacki solution for elastostatics problems.
