WIGNER DISTRIBUTION ANALYSIS OF ACOUSTIC WELL LOGS.
Date of Original Version
The Wigner distribution (WD) mixed time-frequency representation is used to design two heuristic algorithms that can be used to analyze and separate the compressional, shear, pseudo-Rayleigh, and Stoneley wave components of the multicomponent time-varying borehole seismic signals recorded in well logging velocity surveys. The first algorithm uses auto-WD analysis, modification, and synthesis techniques to successively isolate each of the four components. The second algorithm uses a cross-WD synthesis technique which is developed by the authors.
