Title: Application of Spectral Decomposition Methods to the Definition of Stratigraphic Features Associated with Channel Reservoirs in the Southeast Petroleum Province, México
Author ID: info:eu-repo/dai/mx/cvu/175661
Abstract: Spectral decomposition transforms seismic data into the frequency domain via mathematical methods such as the discrete Fourier transform, S-transform, time–frequency continuous wavelet transform and continuous wavelet transform. The transformed results include tuning cubes and a variety of discrete common frequency cubes, which reveal structural and stratigraphic features, such as channels, thin bed reflections, and subtle faults. When a spectral decomposition algorithm is applied to seismic reflection data, it breaks down the seismic signal into its frequency components and this allows visualization of the data at specific frequencies, and identification of stratigraphic and structural features that would otherwise be overlooked in full bandwidth displays. The stratigraphic features delineated through the different algorithms, such as channels and their sedimentary facies, could be related to the presence of reservoir rock, i.e., underground rock units where the oil migrates and accumulates. An example from the Southeast Petroleum Province in México is presented.
