Seismic Inversion by Multispectral Recursive Wavelet Summation. The Multispectral RWS inversion is a novel poststack hybrid sparse spike inversion. The inversion is capable of retrieving all the information contained within the frequency range of the seismic trace. It is a very effective mean of seismic bandwidth extension with gains of over 20dB at the high end.]]>
