... 3-D DMO processing has become a routine procedure in the seismic processing industry. Depending on the shoot- ing geometry, it can be compute- or I/O- intensive, so issues of parallelism need to be addressed for throughput improve- ment. Parallel 3-D DMO is difficult to implement because the output...

..., Kirchhoff-type algorithms are more popular in processing 3-D seis- mic data than those faster Fourier approaches, since the integral DMO can handle the irregularly sampled data (Deregowski, 1987).

... conventional 3-D DMO with more complex algorithms. Spatial sampling should be considered. DMO is a wave- equation process that requires adequate 3-D sampling to avoid spatial aliasing (Beasley and Klotz, 1992). We have seen that the DMC operator has a saddle shape for the case of a linear-interval velocity...
