A New MZO Algorithm and Its Application

A new MZO(migration to Zero offset) algorithm, similar to DMO, is introduced in the paper. It is implemented on the common offset gathers with wave field extrapolation and wave equation migration by finite-difference method. It needs common offset gathers with the same azimuth for 3D seismic survey. The new algorithm runs two times faster than the conventional DMO, leading to the equivalent processing results.
