Applying the phase congruency algorithm to seismic data slices
Speakers
Details
A common problem in seismic interpretation is the search for discontinuities such as faults. The usual approach to identifying these features is the coherency method (Bahorich and Farmer, 1995). The phase congruency algorithm detects corners and edges on two-dimensional images (Kovesi, 2003). We have implemented this algorithm to search for discontinuities on seismic data slices. The theory of phase congruency, comparisons with the coherency method and illustrations of phase congruency with several carbonate examples will be discussed.
