Abstract

Seismic coherency is an important method to measure lateral changes in seismic response. Different methods and various filters were proposed to calculate coherency with higher resolution and less noise. The supertrace technique improves the coherence algorithms’ robustness by concatenating multiple seismic traces to form a supertrace. Supertrace-based first-generation coherence algorithm has been proven to be efficient while being less sensitive to noise as multitrace semblance based algorithm. We propose a supertrace-based coherence algorithm with robust and fast slope estimation. First we demonstrate the necessity of filtering the estimated slopes. Then we show the efficiency and high resolution of the new method with field examples.
