On the basis of coherence algorithms, a new method, i.e., coherence algorithms of eigenstructure-based seismic multi-vector attributes, is studied in this paper. With this method, we can overcome the defect of insufficient information obtained from the singular attribute technique. The multi-vector attributes can be fully used without any contradiction between them. In addition, the geological boundary can be well distinguished. An analysis of the practical data shows that the result is very satisfactory.
