Abstract
Disclosed is a method for characterizing the evolution of a reservoir by determining a seismic wavelet which links observed seismic data to a sequence of reflectivities. The method comprises obtaining seismic data (200) representing seismic changes which have occurred between a first time and a second time, said seismic data comprising a plurality of seismic traces; and performing an optimization operation simultaneously (230) on the seismic traces so as to optimize for said seismic wavelet. The optimization operation may be performed without using known reflectivity data as an input.
