Automatic Horizon Matching across Faults

A method for automatic horizon tracking in reflection seismic data images across discontinuities is described. Horizon tracking is an important task of the structural interpretation of seismic images, however the automatic tracking across discontinuities has still not been solved satisfactorily. The reason for this is the difficulty involved in locating non-ambiguous local correlation features as a result of the small amount of local information contained in seismic reflection images. The method described here provides an enhancement over a solely local feature based analysis by including a high-level deterministic analysis based upon geological and geometrical constraints. Application of the method to typical seismic data images resulted in the successful matching of all major horizons across several normal faults.
