Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3569993
..., a horizontal multiple-layered formation hosting mud-filled borehole model is constructed, and two types of data sets are obtained from the model with fixed conductivity or relative permittivity. The classical short time Fourier transform (STFT) is adopted to analyze the original BHR responses to different...

...-domain are limited. We compare three frequency-domain angle measurement methods: the local slant stacking method, the local windowed Fourier transform method, and the frequency-domain directionalvector-based method. With numerical examples, their accuracies, flexibilities and efficiencies are analyzed...

..., spectral inversion inherits its stability and can resolve thin beds. However, most seismic post-stack data are nonstationary, there are amplitude attenuation, frequency attenuation, and phase distortion. Based on the short-time Fourier transform, we derive a spectral inversion method (with quality factor...

... of the Fourier transform. We demonstrate that the tensor nuclear norm (TNN) of a sampling operator is correlated with the TNN of the corresponding observation, thus producing a useful tool for determining if low rank optimization is appropriate for a given observation. Of the possible six orientations for order...
