Abstract

Gradient structure tensor (GST) is used in attributes extraction commonly, such as dip, azimuth, and discontinuity detection. Usually the GST is constructed on migrated seismic data directly. One important procedure in GST is spatial derivative. The spatial derivative on migrated data contains not only structure information (such as dip and azimuth) but also the spatial change of wave impedance. We construct GST on instantaneous phase to estimate the dip and azimuth, which reflects the geometric structure of layer and eliminates the influence of the lateral change of wave impedance. The results of synthetic example and field-data example show the correctness and validity of our method.
