Abstract: A method is provided for processing seismic data for interpretation. The method includes recording an original seismic data trace, decomposing the original seismic data trace into a set of predefined wavelets, and reconstructing a seismic data trace from, at least a subset of, the set of wavelets.

Abstract: Seismic data traces contain noises that may exist in the form of wavelets and be represented by wavelets. A method is established for removing or attenuating the noises in the seismic data traces by removing the wavelets or representing wavelets of noises in the seismic data traces. The method involves three steps. (1) Decomposition of each seismic data trace into a set of time dependent wavelets of different shapes. The obtained wavelets can be named with their dominant frequency or other characteristics of the wavelets. (2) Proper selection of the wavelets to form a new set of wavelets that contains mostly signal wavelets and rejects the wavelets of noises and representing wavelets of noises as mush as possible. This step can also be described as to remove the wavelets of noises and representing wavelets of noises from the obtained set of wavelets from step one and form a new set of wavelets. (3) Composition or reconstruction of a new seismic data trace with the new selected set of wavelets.
