Seismic Attributes and Time-Frequency analysis by using Wigner-Ville distribution combined with the Maximum Entropy Method
Leonardo Batista, Milton José Porsani · 2017
The growing need for more defined images of seismic attributes for analysis and description of reservoirs encourages the development of new methods that are capable of displaying high resolution images of seismic attributes. Therewith, we propose the use of the method called Maximum Entropy of Wigner-Ville (MEM-WV), that combines the distribution of Wigner-Ville with the Burg's Maximum Entropy method, in order to get the high resolution power spectrum of the seismic signal. In this method, the power spectrum is obtained by doing Fourier Transform (FT) of each Kernel term of Wigner-Ville, and then by estimating and extending each Kernel sequence. In order to better describe hydrocarbon reservoirs, this work will favor the achievement of structural, stratigraphic and geomorphological attributes with higher resolution.
