SUMMARY Wavelet estimation plays an important role in many seismic processes like impedance inversion, amplitude versus offset (AVO) and full waveform inversion (FWI). Statistical methods of wavelet estimation away from well control are a desirable tool to support seismic signal processing. One of these methods based on Homomorphic analysis has long intrigued as a potentially elegant solution t...

The presence of coal in complex structures featuring sandstone reservoirs seriously hinders reservoir characterization and the identification fluids subsurface formations. Coal can strongly obscure reflections from sandstone, easily leading to false bright spots during exploration; thus, their boundaries cannot be accurately described. Furthermore, layers intercalated with thin seams form compo...
