Multicomponent Joint Processing Technologies - Elastic Migration Velocity Analysis and Elastic Reverse Time Migration

The conventional migration velocity analysis and reverse time migration are not specially designed for multicomponent seismic data. We introduce the procedure of implementing multicomponent joint elastic migration velocity analysis. Based on the outputs of the elastic MVA, we analyse the implementation of multicomponent joint elastic reverse time migration. Taken together, these yield powerful and special designed processing technologies for multicomponent seismic data. Multicomponent joint technologies directly use multicomponent seismic data rather than use the P- and S-wave separated scalar or single component seismic data. The whole process can correctly handle elastic vector waves and the energy conversion. Most importantly, the outputs have clear physical meaning which can be directly used in elastic inversion and interpretation.
