Abstract
The present invention relates to a method of processing seismic signals comprising: receiving a set of seismic signals, applying a wavelet transformation to the set of signals and generating transformed signals across a plurality of scales. Then for each scale determining coherence information indicative of the transformed signals and generating a comparison matrix comparing the transformed signals, then outputting seismic attribute information based on combined coherence information.
Claims31
A computer implemented method of evaluating seismic data, comprising:
- receiving, by an input interface of a computer from a second computer via a computer network, a set of seismic signal traces corresponding to seismic volume;
- applying, by a processor of the computer a wavelet transformation to the set of signal traces to generate transformed signals at each of a plurality of scales;
- for each of the scales, determining, by the processor, scale dependent coherence information indicative of a coherence of the transformed signals at the respective scale;
- combining,rocessor, the scale dependent coherence information to generate combined information;
- and
- outputting, by the processor to a display unit of the computer, seismic attribute information based on the combined information for display by the display unit of the computer.
