Improving Time Estimation by Blind Deconvolution: with Applications to TOFD and Backscatter Sizing
Roberto H. Herrera, Zhaorui Liu, Natasha Raffa +2
In this paper we present a blind deconvolution scheme based on statistical wavelet estimation. We assume no prior knowledge of the wavelet, and do not select a reflector from the s…
Time-Frequency Representation of Microseismic Signals using the Synchrosqueezing Transform
Roberto H. Herrera, Jean-Baptiste Tary, Mirko van der Baan
Resonance frequencies can provide useful information on the deformation occurring during fracturing experiments or management, complementary to the microseismic event distri…
Automated seismic-to-well ties?
Roberto Henry Herrera, Mirko van der Baan
The quality of seismic-to-well tie is commonly quantified using the classical Pearson's correlation coefficient. However the seismic wavelet is time-variant, well logging and upsca…
Short-time homomorphic wavelet estimation
Roberto H. Herrera, Mirko Van der Baan
Successful wavelet estimation is an essential step for seismic methods like impedance inversion, analysis of amplitude variations with offset and full waveform inversion. Homomorph…
Application of Fractional Fourier Transform in Cepstrum Analysis
K. H. Miah, R. H. Herrera, M. van der Baan +1
Source wavelet estimation is the key in seismic signal processing for resolving subsurface structural properties. Homomorphic deconvolution using cepstrum analysis has been an effe…
Blind Deconvolution of Ultrasonic Signals Using High-Order Spectral Analysis and Wavelets
Roberto H. Herrera, Eduardo Moreno, Héctor Calas +1
Defect detection by ultrasonic method is limited by the pulse width. Resolution can be improved through a deconvolution process with a priori information of the pulse or by its est…
