Abstract
The present disclosure 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.

-31. (canceled)
A system to detect hydrocarbon deposits, comprising:
- at least one memory that stores seismic signal traces obtained from a seismic survey of a land surface or a seabed;
- one or more processors in communication with the at least one memory, the one or more processors to:
- receive, from the at least one memory, the seismic signal traces;
- transform, via a wavelet transformation, the seismic signal traces to transformed signals at each of a plurality of scales;
- determine scale dependent coherence information for each of the plurality of scales of the transformed signals;
- generate combined information from the scale dependent coherence information for each of the plurality of scales of the transformed signals;
- identify seismic attribute information based on at least one of an amplitude or a phase of the combined information;
- generate one or more images from the seismic attribution information that indicate stratigraphic information corresponding to the land surface or the seabed;
- and
- provide, for display on a display unit in communication with the one or more processors, the one or more images to cause the display unit to display the one or more images.
