Applying the Phase Congruency Algorithm to Seismic Data Slices – A Carbonate Case Study

Introduction Traditionally, the analysis of seismic data involved looking for continuous events on seismic data, from which structural and stratigraphic features could be mapped. However, we are also interested in mapping discontinuous features such as faults and fractures. A method for identifying these discontinuities was first introduced by Bahorich and Farmer (1995) and called the coherency algorithm (although it is important to note that the algorithm looks for lack of coherency in the seismic data). This method, based on cross-correlation between adjacent traces, has remained the industry standard since its introduction and has undergone several major enhancements.
