Abstract
With the introduction of relatively fast globally aptimized post-stack seismic inversion it is now possible to apply post stack seismic inversion of large seismic data volumes. Large seismic data volumes challenge the normal assurnption that a constant wavelet can be used to describe the relationship between acoustic impedance reflectivity and the seismic data for the whole tube. For this reason the determination and use of a spatially varying wavelet has been developed. It is presented below.
