ABSTRACT:
A method for enhancing zero-phase seismic data traces so that subtle geologic features are easier to identify and interpret. In a first embodiment, the method comprises enhancing the amplitudes of at least the peaks and troughs in the zero-phase seismic data traces. This enhancement can be accomplished in a variety of ways. In a second embodiment, the negative second difference is calculated at each sample point along the zero-phase seismic data trace to enhance bends or kinks in the data, as well as peaks and troughs.
